Identification of the novel 7-methyl-6-octadecenoic acid in Holothuria mexicana.
The phospholipid fatty acid composition of Holothuria mexicana was investigated, and the novel 7-methyl-6-octadecenoic acid was identified. Structural characterization was accomplished by means of pyrrolidide derivatization and total synthesis. Other interesting phospholipid fatty acids in H. mexicana were 7-eicosenoic acid, 13-tricosenoic acid, 7-methyl-6-hexadecenoic acid, and 2-hydroxy-15-tetradecenoic acid.
