2. Vitamin C - Wikipedia

   en.wikipedia.org/wiki/Vitamin_C

   Vitamin C is an essential nutrient involved in the repair of tissue, the formation of collagen, and the enzymatic production of certain neurotransmitters. It is required for the functioning of several enzymes and is important for immune system function. [6] It also functions as an antioxidant.

3. Liposome - Wikipedia

   en.wikipedia.org/wiki/Liposome

   Liposome. Scheme of a liposome formed by phospholipids in an aqueous solution. Liposomes are composite structures made of phospholipids and may contain small amounts of other molecules. Though liposomes can vary in size from low micrometer range to tens of micrometers, unilamellar liposomes, as pictured here, are typically in the lower size ...

4. Quercetin - Wikipedia

   en.wikipedia.org/wiki/Quercetin

   Quercetin is the aglycone form of a number of other flavonoid glycosides, such as rutin (also known as quercetin-3-O-rutinoside) and quercitrin, found in citrus fruit, buckwheat, and onions. [2] Quercetin forms the glycosides quercitrin and rutin together with rhamnose and rutinose, respectively.

5. Dehydroascorbic acid - Wikipedia

   en.wikipedia.org/wiki/Dehydroascorbic_acid

   Dehydroascorbic acid (DHA) is an oxidized form of ascorbic acid (vitamin C). It is actively imported into the endoplasmic reticulum of cells via glucose transporters. [1] It is trapped therein by reduction back to ascorbic acid by glutathione and other thiols. [2] The (free) chemical radical semidehydroascorbic acid (SDA) also belongs to the ...

6. Phospholipid - Wikipedia

   en.wikipedia.org/wiki/Phospholipid

   Phospholipids are a key component of all cell membranes. They can form lipid bilayers because of their amphiphilic characteristic. In eukaryotes, cell membranes also contain another class of lipid, sterol, interspersed among the phospholipids. The combination provides fluidity in two dimensions combined with mechanical strength against rupture.

7. Chemistry of ascorbic acid - Wikipedia

   en.wikipedia.org/wiki/Chemistry_of_ascorbic_acid

   Acidity. [] Ascorbic acid is a furan -based lactone of 2-ketogluconic acid. It contains an adjacent enediol adjacent to the carbonyl. This −C (OH)=C (OH)−C (=O)− structural pattern is characteristic of reductones, and increases the acidity of one of the enol hydroxyl groups.
