WebMay 31, 2024 · Fads2 encodes an enzyme crucial for fatty acid synthesis, so increasing the number of Fads2 genes in a fish genome compensates for the dietary dearth of fatty acids such as docosahexaenoic acid (DHA) in freshwater.
WebFatty acid desaturase 2 is a member of the fatty acid desaturase (FADS) gene family. Desaturase enzymes cause desaturation of fatty acids through the introduction of double bonds between defined carbons of the fatty acyl chain. FADS family members are considered fusion products composed of an N-terminal cytochrome b5 -like domain and … WebThe expression of fads2 was 2-fold higher in S than in F rabbits, whereas enzyme activity was higher in F and more oriented toward the desaturation of linoleic acid (90%). In contrast, S showed a higher preference for linolenic acid (38.9 vs 10%). This study identified a single difference in the fads2 amino acid sequence between these two strains.
