| Abstract: | The phospholipid composition and fatty acid composition of the individual phospholipids were determined in erythrocyte membrane of wild Japanese serow, Capricornis crispus, and compared with those of Japanese cattle. Sphingomyelin (SM) contributed more than 50% to the total phospholipids, with only 3% phosphatidylcholine, 30% phosphatidylethanolamine and 11% phosphatidylserine. This phospholipid composition and ratio of phospholipid to protein in erythrocyte membrane of wild serow were quite similar to those of Japanese cattle. However, marked differences in fatty acid composition were found, especially in lignoceric acid 24:0 and nervonic acid 24:1 of sphingomyelin which were major constituents (approximately 60%) of that phospholipid. |
