Ascorbic acid is a substance that supports the functionality of connective and bone tissue in the body. There is only one biologically active isomer—L-ascorbic acid, also known as vitamin C. Vitamin C plays a role in neuropeptides, steroid hormones of the adrenal cortex, tropocollagen formation, collagen modification, tyrosine metabolism, and folic acid metabolism.
