ResumoThe saturated and unsaturated fatty acids of the algae Chlorella and Scenedesmus were examined by paper chromatography, alkali isomerization and gas chromatography. Free fatty acid obtained by saponificaton was about one half in amount of the total lipid. The solid fatty acid amounting to about 13% of the total fatty acid was found to be palmitic acid. Linolenic acid was nearly 40%, while the sum of stearic acid and oleic acid was less than 4%. Tetraenoic acid was found to be present in all the samples used in this experiment. Tetraenoic acid of Chlorella was found to be C16-acid and amounted to 15_??_26%, though it was not found in C18-acid. Hexadecamonoenoic acid was about 10% and it was separated by column chromatography using a silica gel: Celite (2:1) column. Its double bond was found to be at the 3 position, because tridecanal was the product of its ozonide cleavage.
