serine

serine
/ser"een, -in, sear"-/, n. Biochem.
a crystalline amino acid, HOCH2CH(NH2)COOH, found in many proteins and obtained by the hydrolysis of sericin, the protein constituting silk gum. Abbr.: Ser; Symbol: S
[1875-80; SER(UM) + -INE2]

* * *

One of the nonessential amino acids, found in substantial concentrations (sometimes 5–10%) in many common proteins.

It is also an important component of phospholipids. It is used in biochemical and microbiological research and as a dietary supplement and feed additive.

* * *

      an amino acid obtainable by hydrolysis of most common proteins, sometimes constituting 5 to 10 percent by weight of the total product. First isolated in 1865 from sericin, a silk protein, serine is one of several so-called nonessential amino acids for mammals; i.e., they can synthesize it from glucose and do not require dietary sources.

      Serine and some of its derivatives (e.g., ethanolamine) are also important components of a class of lipids (phospholipids (phospholipid)) found in biological membranes.
