Values are means ± s.e.m., N=4 for all preparations except the zebra finch where N=3. Fatty acids are expressed as mol% of total fatty acids. Unsaturation index is the average number of double bonds per 100 fatty acid chains. Chain length is the average chain length of each fatty acid. Fatty acids where all species contained<0.5% are not included.
