butalaninen.

Brit.

/ˌbjuːˈtaləniːn/,

/ˌbjuːˈtalənʌɪn/, U.S.

/ˌbjuˈtæləˌnin/

Forms: 1900s butalanin, 1800s– butalanine.

Origin: Formed within English, by compounding; perhaps modelled on a French lexical item, or perhaps modelled on a German lexical item. Etymons: butyric adj., alanine n.

Etymology: < but- (in butyric adj.) + alanine n., probably after either French butalanine (1865 or earlier) or German Butalanin (1860 or earlier).

Chemistry. Now historical and rare.

A carboxylic acid later identified as the amino acid valine.
