<jats:title>Abstract</jats:title><jats:p>10,12‐Heneicosadiynoic acid (I), 5,7‐hexadecadiynoic acid (IV), and 10,12‐docosadiynedioic acid (VI) were fed to rats. As metabolites 4,6‐undecadiynedioic acid (II), 5,7‐dodecadiynedioic acid (V), and 4,6‐decadiynedioic acid (VII) respectively were isolated from the urine. 10,12‐Heptadecadiynoic acid (III) also yielded metabolite II. Furthermore 9,11‐eicosadiyne (X) and for comparison purposes eicosane (XI), hexadecanedioic acid (VIII), and docosanedioic acid (IX) were fed. X and XI were incorporated into depot fat and liver lipids to a cetain degree. The diynes I, II, IV, and X are new compounds.</jats:p>
