Abstract

Crustaceans were fed on labeled fatty acid impregnated filter-paper for two days and on their natural food for further two days. In crustaceans fed on palmitic acid-1-¹⁴C 58 per cent of the radioactivity was incorporated into the triglycerides and 38 per cent into the phospholipids. In the stearic acid-l-14C fed group 64 per cent radioactivity was in the triglycerides and 34 per cent in the phospholipids. In Gammarus Roeselii 19 per cent of the palmitic acid-1-¹⁴C and 66 per cent of the stearic acid-1-¹⁴C was transformed to monoenoie fatty acids.The ratio of radioactivity of saturated to monoenoie acids was similar in triglycerides and phospholipids In the polyenoic fatty acids there was no measurable radioactivity.
