/ˈproʊˌlin/,

/ˈproʊlən/

Forms: 1900s– prolin, 1900s– proline.

Origin: A borrowing from German. Etymon: German Prolin.

Etymology: < German Prolin (E. Fischer & Suzuki 1904, in Berichte der Deutsch. Chem. Ges. 37 2843), < prol- (representing Pyrrolidin pyrrolidine n.) + -in -ine suffix⁵.

Biochemistry.

A heterocyclic imino acid which occurs in proteins and is a major constituent of collagen.Chemical name: 2-pyrrolidinecarboxylic acid; C₅H₉NO₂.

1904 Jrnl. Chem. Soc. 86 i. 917 (heading) Derivatives of prolin.

1904 Jrnl. Chem. Soc. 86 i. 917 The proline used was derived from gelatin.

1946 Nature 5 Oct. 474/2 All the proline residues appear to be situated at points roughly one third and two thirds along the length of the molecule.

1973 Biggs & Woodson Clin. Biochem. iii. 38 All amino acids—with the exception of proline, which has an imino group—have an amino group on the α carbon.

1992 C. A. Smith & E. J. Wood Biosynthesis i. 9 (caption) The prolamines are a group of proteins from cereals containing up to 15% of proline and 30–45% glutamic acid, but only low concentrations of essential amino acids.
