Pantethine is a dietary supplement, which is a derivative of pantothenic acid, sourced from vitamin B5. As a biologically active compound, it undergoes conversion to pantetheine, which then forms coenzyme A (CoA) and acyl-carrier proteins. This conversion is critical, as CoA is an essential cofactor involved in numerous biochemical reactions that are integral to fatty acid metabolism, among other processes. The primary mode of action of Pantethine involves the modulation of lipid metabolism. It plays a role in reducing the synthesis of low-density lipoprotein (LDL) cholesterol and triglycerides while potentially enhancing high-density lipoprotein (HDL) cholesterol. Pantethine achieves this by influencing enzymes like acetyl-CoA carboxylase and HMG-CoA reductase, which are key in the lipid biosynthesis pathway. Applications of Pantethine are mainly in the field of cardiovascular health, where it is utilized to maintain healthy lipid levels in individuals at risk for hyperlipidemia. Research has demonstrated its potential benefits in reducing cardiovascular disease risk factors and supporting overall metabolic health, making it a subject of interest in clinical and biochemical studies.
