维生素C在动物脂质代谢中的多维调控作用研究进展OA

Lipid metabolism plays an important role in animal health and production efficiency.As an essential water-soluble antioxidant vitamin,vitamin C exerts multiple regulatory effects on lipid metabolism in animals.Studies have shown that vitamin C can scavenge free radicals,reduce malondialdehyde content,alleviate lipid peroxidation damage,and enhance antioxidant enzyme activities,thereby maintaining redox homeostasis.Meanwhile,vitamin C can regulate key metabolic processes such as fatty acid oxidation and cholesterol conversion,and modulate the expression of lipid metabolism-related genes,as well as changes in the enzymatic activity of cAMP-associated signaling pathways.In livestock and poultry production,vitamin C can alleviate the adverse effects of weaning and heat stress on lipid metabolism,improve growth performance,and reduce hepatic lipid deposition.In aquatic animals,vitamin C contributes to the maintenance of lipid metabolic balance and promotes growth and immune function.However,the application effects of vitamin C are influenced by multiple factors,and further studies are still required to provide more precise guidance for animal production.
