Vitamin C (English: Vitamin C / ascorbic acid, also known as L- ascorbic acid) is an essential nutrient for higher primates and other minority organisms. Ascorbic acid in the metabolism of many organisms can be produced, but humans are the most notable exceptions. The most widely known is the lack of vitamin C can cause scurvy.
Vitamin C is ascorbic acid pharmacophore ion. In vivo, vitamin C is an antioxidant because of its ability to protect the body against threats oxidant, vitamin C is also a coenzyme
However, because vitamin C is an essential nutrient, and its use is recommended daily amount is often discussed. It is used as a food additive, an antioxidant vitamin C becomes acidity adjusting agents and preservatives. A plurality of E prefix number (E number) included vitamin C, different numbers depending on its chemical structure, such as ascorbic acid E300, E301 ascorbic acid sodium salt, E302 ascorbic acid calcium salt, E303 ascorbic acid potassium salt, E304 ascorbic acid and ascorbic acid esters of palmitic acid, E315 for erythorbate pyrethrins. Each protein has its own unique amino acid sequence, which consists of information from the gene encoding the amino acid sequence of the protein corresponding to the nucleotide sequence of the decision. Genetic code is a set of three nucleotide codon, for each combination of three nucleotides may encode a particular amino acid, such as AUG mRNA on (as in DNA ATG) encoding a methionine .
Protein components, mainly the four elements of carbon, hydrogen, oxygen, nitrogen, etc. constituted, the presence of nitrogen which is different from the protein and carbohydrate fat. Other proteins are still a small number of elements sulfur, phosphorus, iron, and copper.
The molecular weight of the protein, by 13,000 to several million dollars, so a lot of protein molecules larger than carbohydrates and fats.
