phrenosinn.

Brit.

/ˈfrɛnəsɪn/, U.S.

/ˈfrɛnəs(ə)n/

Forms: 1800s– phrenosin, 1800s– phrenosine.

Origin: Formed within English, by derivation. Etymons: phreno- comb. form, -ose suffix², -in suffix¹.

Etymology: < phreno- comb. form + -ose suffix² + -in suffix¹ (see quot. 1878). Compare German Phrenosin (1881 or earlier).

Biochemistry.

A cerebroside, C₄₈H₉₃NO₉, which on hydrolysis yields galactose, sphingosine, and a long-chain alpha-hydroxy fatty acid.
