Abstract
    A large quantity of triglyceride was detected histochemically in nutrient-deposit cells of the trophosome in the beard worm (Oligobrachia mashikoi). The lipid extracted from the trophosome was composed of triglyceride, several kinds of phospholipid, free fatty acid, cholesterol, and cholesterol ester. The fatty acid of the triglyceride was comprised mainly of a monoenoic type, such as palmitoleic acid (16:1) and oleic acid (18:1), which accounted for 31% and 37% of the total fatty acids, respectively. In addition, in blood triglyceride, the fatty acid composition was almost the same.
