How many common amino aicds are in the structrue of proteins?
20
37
Describe the structure of the amino acids
most of the amino acids (expect proline)
are ***alpha amino acids***:
the **amino group** (NH2) is linked to the **same carbon atom** to which the **carboxyl group** (COOH) is attached.
38
Derived amnio acids ***found*** in proteins
after biosynthesis, some of the common amino acids are modified resulting these derived amino acids.
**Example:** hydroxyproline, hydroxylysine, N-formylmethionine (fMet)
39
Derived amino acids ***not found*** in proteins
these amino acids are present in the cells as free amino acids (are not components of proteins) and are produced during the metabolism of amino acids.
**Examples**: homocysteine, homoserine, ornithine, citrulline, dihydroxphenylalanine (DOPA),
gamma-aminobutyric acid (GABA), taurine, monodotyrosine (MIT), diiodtyrosine (DIT), triiodthyronine (T3), tetraiodthyronine or thyroxine (T4)
