| Variation in triacylglycerols(TGs) and fatty acids in Fucus serratus was analyzed for a period of one year. TGs were more concentrated during the summer(2.8mg/g dw)and autumn(2.6mg/g dw) than during the spring (0,7mg/g dw)and winter (0.5mg/g dw). The dominant fatty acides in total liqid were palmitic acid ($C_{16:0}$, 24.1%), oleic acid (($C_{18:1}$, 22.4%) and arachidonic acid (($C_{20:4}$, 14.4%) but the dominant ones in TG were $C_{16:0}$(22.8%), $C_{18:1}$(36.4%) and $C_{18:2}$(linoleic acid, 16.4%). The levels of $C_16$ fatty acids were high in winter while $C_18$ in summer and autumn. The polyunsaturated fatty acids (UFAs) were more abundant in the $C_20$ series, while the UFAs of the $C_16$ were low. Especially, the amount of arachidonic acid ($C_{20:4}$, 14.4% of total fatty acids (TFA) was more abundant than that of eicosapentaenoic acid ($C_{20:5}$, 10.4% of TFA). The amount of $C_{20:4}$ and $C_{20:5}$,in TG was 9.2% and 4.8%, respectively. These UFAs in total lipid were thus higher than TG. Therefore, the synthesis of TG and fatty acid was stimulated by the alternation of emersion and submersion of thalli from sea water and eco-physiological conditions during summer: high temperature and light, and low concentration of nitrogen. |
