✦ Synopsis

Preparations of Euchaeta norvegica eatalyse the incorporation of (1-14C) hexadecanol, (9,10-~H~) oleie acid, (U-I~C) glucose, (U-I~C) alanine and (U-I~C) aspartie acid into wax esters. Both the fatty alcohol and fatty acid moieties of the wax esters are labelled, indicating de novo biosynthesis. A limited interconversion of fatty acid and fatty alcohol has been demonstrated. Incorporation of glucose into wax esters is diminished by prior starving of E. norvegica; it is also reduced in the presence of ecdysterone. ~ormation of wax esters fl-om glucose is inhibited by increased oxygen tensions, rotenone and dinitrophenol, and is relatively insensitive to decreased oxygen tensions and cyanide. The data are discussed with particular reference to the reasons why wax esters are biosyathesised by calanoids.
