What role do vitamins play in the body?

Vitamins are complex ol organic compounds that are necessary in small quantities for the normal functioning of organisms. Unlike other organic substances, vitamins are not used as a source of energy or building material.
The biological effect of vitamins in the human body is the active participation of these substances in metabolic processes. Vitamins take part in the exchange of proteins, fats and carbohydrates, either directly or as part of complex enzyme systems. Vitamins are involved in oxidative processes, as a result of which numerous substances are used from carbohydrates and fats, which are used by the body as energy and plastic materials. Vitamins contribute to the normal growth of cells and the development of the whole organism. An important role is played by vitamins in maintaining the body’s immune responses, ensuring its resistance to adverse environmental factors.
