This review article gives a survey of the generally accepted biosynthetic pathways that lead to water-soluble vitamins in microorganisms, plants and some animals. The biosynthetic pathways leading to the B-group vitamins (thiamin, riboflavin, nicotinic acid and nicotinamide, pantothenic acid, vitamin B6) are described in detail using the reaction schemes, sequences, and mechanisms with the enzymes involved and detailed explanations based on chemical principles and mechanisms.
