Vitamin C Loss In Teleost Fishes
It was originally believed that all fish species lacked the ability to synthesize ascorbic acid and that vitamin C synthesis had first appeared in amphibians . There have also been studies which claimed that some teleost fish species could synthesize vitamin C and a study that claimed that some non-teleost fishes could not synthesize vitamin C . However, it has now been established that all cartilaginous and non-teleost bony fish species are able to synthesize vitamin C and that no teleost fish species can do so . The ability to synthesize vitamin C has been observed in hagfish, lampreys, sharks, rays, lungfish, coelacanths, sturgeons and bowfins, among others, but never in any of the numerous teleost fish species which have been studied . This demonstrates that vitamin C synthesis is an ancestral trait of vertebrates and that it was lost in the common ancestor of teleost fish . Since several ancestral actinopterygian fish species synthesize vitamin C, this mutation must have occurred some 200 to 210 MYA .

Greeting to all you beautiful girls out there! This is my first contribution to IMBB and I truly hope that all of you enjoy reading it. Each one of us is beautiful inside and beautiful skin is achievable. A disciplined lifestyle, regular workout and drinking plenty of water is the secret to life long healthy and glowing skin. You only need the patience and determination to make it work for you.
I have been blessed with clean and healthy skin even though I was the darkest of my two very pretty sisters. But, on the whole I had no real complaint, which is until now. In the last six months, I got a taste of almost all kinds of skin issues like skin rashes, acne, blemishes, large pores, dark patches and uneven skin tone. My face turned into a battleground where the only one getting beaten was me!
What did I do? Well I guess the right question would be What didnt I do? Everything under the sun. From Olay to Garnier to LOreal to The Body Shop. And makeup to hide their after effects! And I thought, well it was good while it lasted. But my search for that perfect magic potion continued. While going for a month long break, I packed all my so called magic bottles and decided to rely on the home made ubtans for a while. Thats when I read somewhere that I could make my own Vitamin C serum for practically no cost.

Vitamin C Loss In Birds
The first extensive study of the capacity to synthesize vitamin C in birds showed that whereas most bird species studied were able to synthesize vitamin C, the organ where it was synthesized varied . It was synthesized in the kidneys of 7 species, the kidneys and liver of 2 species, the liver of 5 species and by neither organ in one species. Because the species where vitamin C synthesis was either absent or only found in the liver were all Passeriformes birds, an evolutionarily more recent taxon, the authors interpreted their data as reflecting an evolutionary ascent where vitamin C synthesis went from the kidney to the liver and then disappeared altogether .
Phylogenetic distribution of the ability to synthesize vitamin C in birds. Lineages able to synthesize vitamin C are in black, those incapable are in gray and empty branches represent ancestral lineages where the status of vitamin C production is not known. The phylogenetic relationships are based on those in reference and the start next to the Terpsiphone genus indicates that it is now known to belong to the Corvidea family. The complete species list, species names and references are given in Supplemental Table 4.

Ascorbic Acid And Atherosclerosis
Lipid peroxidation and oxidative modification of low density lipoproteins are implicated in development of atherosclerosis . Vitamin C protects against oxidation of isolated LDL by different types of oxidative stress, including metal ion dependent and independent processes . Addition of iron to plasma devoid of ascorbic acid resulted in lipid peroxidation, whereas endogenous and exogenous ascorbic acid was found to inhibit the lipid oxidation in iron-over loaded human plasma . Similarly, when ascorbic acid was added to human serum supplemented with Cu2+, antioxidant activity rather than pro-oxidant effects were observed .
Ascorbic acid is known to prevent the oxidation of LDL primarily by scavenging the free radicals and other reactive oxygen species in the aqueous milieu . In addition, in vitro studies have shown that physiological concentrations of ascorbic acid strongly inhibit LDL oxidation by vascular endothelial cells . Adhesion of leukocytes to the endothelium is an important step in initiating atherosclerosis. In vivo studies have demonstrated that ascorbic acid inhibits leukocyte-endothelial cell interactions induced by cigarette smoke or oxidized LDL . Further, lipophilic derivatives of ascorbic acid showed protective effect on lipid-peroxide induced endothelial injury .
Choose The Right Concentration
Identifying the right concentration for your skin type is essential to how effective your topical vitamin C will be, says New York City dermatologist Dr. Patricia Wexler. “Begin with a low concentration of 10% and increase to 15% or 20% as tolerated,” she instructs. For oily or normal skin, L-ascorbic acid is the most potent form of vitamin C and can be the most beneficial, while for dry and sensitive skin, magnesium ascorbyl phosphate, a water-soluble vitamin C, is less irritating.

Stability Of Your Vitamin C Product
L-ascorbic acid is a highly unstable molecule. It requires a water-based environment, a low pH, and antioxidants to increase its ability to deeply penetrate the skin.
Those conditions are important for creating a stable and active vitamin C product. It is essential to understand why L-ascorbic acid requires these conditions when choosing a vitamin C product in order to find one that is effective and long-lasting.
L-ascorbic acid has a reduced ability to penetrate the skin at its natural pH which is a result of its molecule structure. L-ascorbic acid is a charged molecule and is hydrophilic. These two characteristics mean that L-ascorbic acid will readily bind to water molecules, making it hard for the molecule to pass through the skins hydrophobic layers.
Reducing the pH of a product to less than 3.5 or less makes it more acidic, allowing for L-ascorbic acid to penetrate deeper and be stable for longer. However, reducing the pH of the product may lead to sensitization of the skin, as the natural pH of the skin is around. It is important to know the concentration of the product .
To create a more stable product that lasts longer, some formulations use different forms of vitamin C. This includes magnesium ascorbyl phosphate or ascorbyl-6-palmitate, which are more stable at a neutral pH. However, a study conducted by Duke University Medical Center found that these two substitutes did not increase the natural vitamin C levels in the skin.
Do You Really Have To Use Organic Oranges For This Recipe
Organic fruit is a MUST for this recipe, since insecticide and pesticide residues are typically applied multiple applications throughout the growing season, and in one study, 95% of samples had pesticides on them. I have read that these chemicals can penetrate into the peel of citrus fruits , and while that does make sense, I don’t know if that’s true or not.

What To Consider Before Doing It Yourself
Before you make your own Vitamin C serum, you have to consider several things including the availability and cost of ingredients, the equipment you need as well as the fact that you might go through several failed attempts.
Lets take a closer look.
First, it is important to use the right carrier in your formula, especially for DIY 20 vitamin serum. Most DIY recipes recommend using water, which will allow the vitamin C to recrystallize when its spread on the skin.
This means it will not be able to penetrate and result in any of its amazing benefits. Some do it yourself recipes on how to make vitamin C serum at home use alcohol as a carrier, but this can cause irritation to the skin.
Glycerin can work better as a carrier than water or alcohol, but the fact that it is water-soluble means it will be unable to penetrate the skins lipid-based barrier. Basically, it will penetrate your skin, but not as effectively as a professionally formulated mixture would, and you would be missing out on a lot of the benefits you could be reaping.
Next, you need to consider the fact that the skins natural pH is between 5.5 and 6.5. To maintain this pH balance and avoid irritating or drying out your skin with the acidic 2.2-2.5 pH of your primary ingredient, commercially available products are formulated between 2.8 and 3.4 pH.
As mentioned above, learning how to make a stable vitamin C serum at home is very difficult.
How To Make Liposomal Vitamin C At Home
This page contains affiliate links.
Liposomal Vitamin C is the most absorbable form of vitamin C however it can be very costly if you use it in therapeutic amounts frequently. On the other hand, liposomal vitamin C is not hard to make and can be very cost-effective if made at home. However, this method does not guarantee 100% encapsulation of vitamin C.
Why Liposomal Vitamin C?
Liposomal Vitamin C provides much higher absorption of the vitamin by our cells compared to other forms of the vitamin. Liposomal formulation enhances the ability of vitamin C to absorb directly into cells increasing the effectiveness. Some experts such as Thomas Levy, MD, JD, say that 6 grams of liposomal vitamin C can provide equal benefits of 50 grams of intravenous vitamin C. Intravenous vitamin C treatments are expensive and time-consuming while making liposomal vitamin C is much cheaper and saves the time. So why not make our own liposomal vitamin C?
Homemade liposomal vitamin C makes about 50-85% encapsulation according to a crude test, which is still an excellent uptake of vitamin C. Even at 50% encapsulation the person gets at least as much sodium ascorbate as if a person were to receive it in an IV.
Which one to use: Sodium ascorbate or Ascorbic acid?
Sodium ascorbate is the buffered form of ascorbic acid. Ascorbic acid is too acidic and sodium ascorbate is less acidic . Since the body is slightly alkaline , it is best to use the less acidic form of vitamin C to encapsulate.

Uptake Kinetics Into Rbcs
Isolated RBCs were incubated in PBS containing 3, 5 or 25 mM glucose and 100 µM ascorbate with or without ascorbate oxidase at room temperature. Ascorbate does not oxidize to DHA in PBS at room temperature , so we did not work on ice to prevent RBCs from apoptosis by coldness. Every 15 or 30 min, a sample was taken, washed once with ice cold PBS and osmotically broken by addition of ultrapure water. Vitamin C was stabilized by the addition of 5% PCA and ascorbate concentration was determined by HPLC as described below.

How Vitamin C Works For Youthful Skin
Vitamin C is one of natures amazing and naturally occurring antioxidants in nature. While plants can synthesize the vitamin C into useful form, our bodies cannot because we are missing the enzyme L-glucono-gamma lactone oxidase that is required for the synthesis of vitamin C.
That is why we have to obtain our vitamin C from citrus fruits, strawberries, raspberries, papaya and vegetables, like leafy greens and broccoli. Sailors knew this having carried vitamin C-rich foods during their travels to help them avoid scurvy and other diseases. Eating forms of vitamin C is definitely crucial in good health, but absorption of it is limited.
Therefore, applying a DIY vitamin C serum topically can be of great benefit to the skin and can become a part of your natural skin care routine.
