WebSIRT1 inhibits hepatic FFA and TG synthesis by inhibiting a key lipogenic activator, SREBP-1c, and stimulates β-oxidation by targeting PPARα and its coactivator, PGC-1α . SIRT1 deacetylates SREBP-1c at Lys-289 and Lys-309, and downregulates its transcriptional activity on its lipogenic target genes, such as FASN and ACC . WebFatty acid metabolism. 13 languages. Fatty acid metabolism consists of various metabolic processes involving or closely related to fatty acids, a family of molecules classified within the lipid macronutrient category. These processes can mainly be divided into (1) catabolic processes that generate energy and (2) anabolic processes where they ...
In biochemistry, fatty acid synthesis is the creation of fatty acids from acetyl-CoA and NADPH through the action of enzymes called fatty acid synthases. This process takes place in the cytoplasm of the cell. Most of the acetyl-CoA which is converted into fatty acids is derived from carbohydrates via the … See more Straight-chain fatty acids occur in two types: saturated and unsaturated. Saturated straight-chain fatty acids Much like β-oxidation, straight-chain fatty acid synthesis occurs via the six recurring reactions shown … See more Branched chain fatty acids are usually saturated and are found in two distinct families: the iso-series and anteiso-series.

WebFeb 1, 2008 · FFA synthesis rate (per gram of tissue) increased by 3-fold in BAT. This level was maintained during the first 24 h of reacclimation and decreased by 48 h. In WAT, the opposite was found (i.e., synthesis declined 3-fold and then started slowly to recover during reacclimation) ( Fig. 3A ). WebApr 1, 2016 · As a source of energy, ethanol (EtOH) favours fat accumulation, then stimulates FFA synthesis through activation [Kalaany and Mangelsdorf, 2006] and/or expression [Yin et al., 2007] of sterol regulatory element-binding protein 1c (SREBP-1c), a transcription factor for lipogenic enzymes such as fatty acid synthase (FAS).
WebPhysiologic increases in plasma FFA levels cause insulin resistance in both diabetic and nondiabetic subjects by producing several metabolic defects: (1) FFA inhibit insulin-stimulated glucose uptake at the level of glucose transport or phosphorylation (or both); (2) FFA inhibit insulin-stimulated glycogen synthesis; and (3) FFA inhibit insulin ...
