butyricadj.

Brit.

/bjuːˈtɪrɪk/, U.S.

/bjuˈtɪrɪk/

Etymology: Formed as butyr n. + -ic suffix.

Chemistry.

Of or pertaining to butter, esp. in reference to its chemical constitution and formation. Hence:

1. butyric acid n. the monatomic, monobasic, fatty acid of the butyl n. series, C₄H₈O₂, of which there are two modifications, normal butyric and isobutyric acid; the former occurring in butter, cod-liver oil, and other substances, is a colourless viscous liquid, with a smell suggestive of both vinegar and rancid butter. Its salts are butyrates.
