Lipoic acid ((R)-(+)-α-Lipoic acid) is an antioxidant and an essential cofactor of mitochondrial enzyme complexes. It is the form biosynthesized in humans which is essential for aerobic metabolism and is the nutritionally and therapeutically preferred form due to its "vitamin-like" role in metabolism. It is the only form that exists in nature and acts as an essential cofactor of four mitochondrial enzyme complexes. The (R)-(+)-α-Lipoic acid form is more effective than racemic Lipoic acid.
- Antioxidant
- Essential cofactor of mitochondrial enzyme complexes
- (R)-(+)-α-Lipoic acid is more effective than racemic Lipoic acid
