Short chain fatty acids increase fat oxidation and promote browning ...
However, whether SCFAs reduce lipid accumulation by promoting β- oxidation and browning in 3T3-L1 adipocytes remains unclear. In this study, the expression levels of mitochondrial biogenesis related genes, brown and beige adipocyte-specific factors were measured to determine whether SCFAs promote thermogenesis to reduce lipid accumulation .
Excessive ROS promotes fat synthesis and decreases fatty acid β- oxidation , leading to the accumulation of triacylglycerols in hepatocytes [103]. Recent research has focused on the intricate relationships between oxidative stress, lipid metabolism, and mitochondrial morphology and bioenergetics [104, 105].
Progression to Obesity
Progression to obesity is ultimately linked to the overall net energy balance and activity of different metabolic fluxes. This is particularly evident from variations in fatty acids oxidation , metabolic fluxes through the pyruvate-phosphoenolpyruvate-oxaloacetate node, and extracellular accumulation of Krebs cycle metabolites, such as citrate.
Hepatic fat accumulation results from an imbalance between lipid acquisition and lipid disposal, which are regulated through four major pathways: uptake of circulating lipids, de novo lipogenesis (DNL), fatty acid oxidation (FAO), and export of lipids in very low-density lipoproteins (VLDL) (Fig. 2).
For example, if increased fat oxidation in the mitochondria takes place and acetyl-CoA accumulates in excess, L-carnitine is able to buffer the accumulation of acetyl-CoA by generating acetyl-carnitine, which is now able to cross the mitochondrial membranes and be excreted out of the cell into the blood or urine (6).
New work shows that the microbe-derived metabolite δ-valerobetaine contributes to obesity and hepatic steatosis by modulating mitochondrial fatty acid oxidation and increasing lipid storage in ...
Synergistic Effects of Bioactive Compounds on Human Adiposity ...
Moving forward, it's essential to keep these visual contexts in mind when discussing Oxidation And Promoting Fat Accumulation.
Bioactive compounds derived from food like polyphenols, alkaloids, terpenoids, peptides, and fibers have been recognized as significant influencers of fat metabolism. They operate through various molecular and systemic pathways, facilitating either adiposity reduction or fat accumulation based on the physiological context.
Genetic predisposition, combined with excessive caloric intake, leads to visceral fat accumulation and adipose tissue hypertrophy. This expansion induces mitochondrial dysfunction and the overproduction of reactive oxygen species (ROS), causing oxidative damage and the suppression of adiponectin secretion.
Key Details About Oxidation And Promoting Fat Accumulation
Mitochondria empower the liver to regulate lipid homeostasis by enabling fatty acid oxidation during starvation and lipogenesis during nutrient-rich conditions.
