Amino acids nomenclature pdf

The amine group is located by the position number. Groups that are attached to the nitrogen atom are located using “N” as the position number. More complex primary amines are named with —NH2 as the amino substituent. • Aromatic amines: named as derivatives of the parent compound aniline. 21 rows · Uncommon amino acids. In addition to the 20 common amino acids, there are several uncommon ones found: Hydroxylysine and hydroxyproline. These are found in the protein collagen. Collagen is a fibrous protein made up of three polypeptides that form a stable assembly, but only if the proline and lysine residues are hydroxylated. Higher Unbranched Amino Acids Thefunctional prefix 'amino' is included in the symbol as the letter 'A' and 'diamino' as 'A2'. Thetrivial nameoftheparent acid is abbreviated to twoletters, based, whenpossible, onthesymbolsforlipid nomenclature [19].

If the amino group of the N-terminal residue is free, the residue may be named as an acyl group under 3AA ; indeed any internal residue is an N-substituted amino-acyl group. Residues are named from the trivial name of the amino acid, omitting the word ‘acid’ from aspartic acid and glutamic acid. The amine group is located by the position number. Groups that are attached to the nitrogen atom are located using “N” as the position number. More complex primary amines are named with —NH2 as the amino substituent. • Aromatic amines: named as derivatives of the parent compound aniline.

These recommendations were prepared by the IUPAC-IUB Joint Commission on Biochemical Nomenclature (JCBN), whose members were H. B. F. Dixon (chairman), A. Cornish-Bowden (secretary), C.
