Assimilation of dietary eicosenoic and erucic acid esters

  • Published:
Journal of the American Oil Chemists Society

Summary

  1. 1.

    Eicosenoic acid, fed to rats as methyl ester to the extent of 5% by weight of the diet, was deposited in substantial amount in the body fat.

  2. 2.

    Erucic acid, fed in the same way, was deposited in considerably lesser amount.

  3. 3.

    Neither of these acids appeared to be as readily deposited in body fat as the linoleic acid of corn oil.

  4. 4.

    The three monounsaturated acids, oleic, eicosenoic, and erucic, were apparently deposited without alteration in chain length or degree of saturation. There was no evidence of conversion of eicosenoate to arachidic or stearic acids, or of erucate to behenic, arachidic, or stearic acids in any appreciable amount. Similarly there appeared to be little or no conversion of eicosenoate to oleic acid or of erucate to eicosenoic acid.

  5. 5.

    The eicosenoate in the diet was not converted to arachidonic acid by the animal.

  6. 6.

    The amount of total fat deposited and the proportion in carcass, skin, and viscera were approximately the same on diets of oleate, eicosenoate, and erucate.
