butyricadj.
/bjuːˈtɪrɪk/, U.S. /bjuˈtɪrɪk/ 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.

1826 W. Henry Elem. Chem. II. 446 This oil [butter], according to Chevreul, is resolvable into two; the one..he calls butirine, because it contains butyric acid or its elements.
1839–47 Todd's Cycl. Anat. & Physiol. III. 359/1 Chevreul..has named them the butyric, caproic, and capric acids.
1845 G. E. Day tr. J. F. Simon Animal Chem. I. 78 By..fermentation butyric acid may be obtained from sugar..the fermentation, at first viscous, subsequently lactic, gradually becomes butyric.
1871 J. Tyndall Fragm. Sci. (ed. 6) II. xii. 275 Air..is according to Pasteur, absolutely deadly to the vibrios which provoke the butyric acid fermentation.
2. butyric series: the series of compound bodies related to butyric acid, or containing the radical butyryl n. at butyr- comb. form , C4H7O; as butyric aldehyde, C4H8O; butyric ether or ethyl butyrate, C2H5·C4H7O2, a colourless oily liquid, having a pleasant fruity odour; butyric anhydride or oxide(C4H7O)2O.
