Abstract: Phosphatidic acid obtained from the heart of a rorqual was found to possess the following characteristies: P 3.96%; N 0.07%; and the iodine value 112.1. Glyceryltriglycero phosphoric acid was isolated as barium salt from its hydrophoslyzate, so the skeletal structure of the phosphatidic acid was supposed to be similar to cardiolipin. Sodium salt of the phospatidic acid showed a strong activity as haptene for the serodiagnosis of syphilis. The percentage composition of its component, fatty acids, estimated spectrophotometrically after they had been converted to conjugated acids by KOH-glycol reagent, was as follows: saturated 34.0; monoethylenic 13.8; dienoic 9.0; trienoic 23.6; tetraenoic 12.1; pentaenoic 6.2; and hexaenoic 1.3.
