Generally, polyunsaturated FAs and monounsaturated FAs were major components (50-77%). Total saturated FAs ranged from 22% to 50%, with 16: 0 as the most abundant saturate (32-38%). Two samples of Cystoseira barbata collected from a different station had some differences from each other in their contents of 18: 2n-6 and 18: 3n-3 and in the 18: 2n-6/20: 4n-6 ratios. Green algal species had a significantly higher proportion of unsaturated FAs and a significantly lower proportion of saturated FAs than the red and brown algae. The amount of n-3 FAs was significantly higher in Ulva rigita, Chaetomorpha linum, Enteromorpha linza and Gracilaria verrucosa (8.88, 6.44, 5.31 and 5.24, respectively). © 2007 Taylor & Francis.eninfo:eu-repo/semantics/closedAccessAlgae; Chlorophyta; Lipids; n-3 fatty acids; Phaeophyta; RhodophytaArticle89237137910.1080/027722406010123662-s2.0-34248206595Q3
