Identification and Quantification of Fatty Acids in T. viridissima, C. biguttulus, and C. brunneus by GC-MS

Table 2

The average concentration and standard deviation, of each fatty acid across the three lipid fractions: neutral lipids, free fatty acids, and polar lipids. The results are based on three sample preparations, each including three parallels of each fraction, for T. viridissima. All values are presented as µg/g of dry matter.
