GODINEZ ORTEGA, José Luis; ROBLEDO RAMIREZ, Daniel; FREILE PELEGRIN, Yolanda  e  RIOS CASTILLO, Tirso. Composición estacional de ácidos grasos de Halymenia Floresii (Rhodophyta) de Yucatán, México. Rev. latinoam. quím [online]. 2012, vol.40, n.2, pp.99-105. ISSN 0370-5943.

Seasonal variation of fatty acid composition of Halymenia floresii (Rhodophyta algae) was determined by conventional methods and gas chromatography-mass spectrometry (GC-MS). Three saturated fatty acids (SAFA) were identified (C14:0, C16:0, C18:0) and a monounsaturated (MUFA) C18:1 Δ9. Results indicated a constant SAFA/MUFA proportion throughout the year (dry and rainy season), except in the windy season where MUFA increased and particularly oleic acid. In general, H. floresii has a good supply of fatty acids compared with commercial algae such as nori (Porphyra sp.) and dulse (Palmaria palmata).
