Overview

A six carbon compound related to glucose. It is found naturally in citrus fruits and many vegetables. Ascorbic acid is an essential nutrient in human diets, and necessary to maintain connective tissue and bone. Its biologically active form, vitamin C, functions as a reducing agent and coenzyme in several metabolic pathways. Vitamin C is considered an antioxidant.

Indication

Used to treat vitamin C deficiency, scurvy, delayed wound and bone healing, urine acidification, and in general as an antioxidant. It has also been suggested to be an effective antiviral agent.

A Comprehensive Monograph on L-Ascorbic Acid (Vitamin C): From Chemical Structure to Clinical Application

Introduction and Historical Context: The Conquest of Scurvy and the Identification of a Vital Molecule

Overview of L-Ascorbic Acid

L-ascorbic acid, universally known as Vitamin C, is an essential water-soluble vitamin and a small molecule drug cataloged under DrugBank ID DB00126.[1] It is a six-carbon compound structurally analogous to glucose, which is indispensable for human health.[1] Unlike most vertebrates, humans lack the enzyme L-gulonolactone oxidase, which catalyzes the final step in ascorbic acid biosynthesis, making it an essential nutrient that must be obtained exogenously through diet.[3] Its fundamental physiological roles are vast and critical, encompassing the maintenance of connective tissue and bone, functioning as a primary reducing agent and coenzyme in numerous metabolic pathways, and serving as one of the body's most potent and vital antioxidants.[1]
