The sterols and fatty acids from purified flagella of<i>Chlamydomonas reinhardi</i>

Abstract

Abstract Purified flagella of the eukaryotic alga Chlamydomonas reinhardi have a sterol composition (55% ergosterol [24β‐methylcholesta‐5,7,22‐ trans ‐trien‐3β‐ol] and 45% 7‐dehydroporiferasterol [24β‐ethylcholesta‐5,7,22‐ trans ‐trien‐3β‐ol]) identical of that of the whole algal cell. Fatty acids isolated from C. reinhardi flagella were identified as 16∶0, 18∶0, 18∶1, 18∶2 and 18∶3. Whole cell fatty acids included 14∶0, 16∶2 and 16∶3 in addition to those found in the flagella. Triunsaturates comprised 22.9% of the flagellar fatty acids and 76.4% of those from the whole cell.
