The B vitamin complex (also called B vitamins) are a group 8 vitamins. They have an important job in the metabolism of cells. Originally, people thought they were just different forms of one vitamin (like with Vitamin D, for example). Later it turned out that they are separate vitamins that often can be found together.
The name vitamin B12, known as vitamin B12 (commonly B12 or B12 for short) or also cyanocobalamin generally refers to all forms of the vitamin.Vitamin B12 is a water soluble vitamin with a key role in the normal functioning of the brain and nervous system, and for the formation of blood. It is one of the eight B vitamins.
Pantothenic acid, also called vitamin B5 (a B vitamin), is a water-soluble vitamin required to sustain life (essential nutrient). Pantothenic acid is needed to form coenzyme-A (CoA), and is critical in the metabolism and synthesis of carbohydrates, proteins, and fats. In chemical structure, it is the amide between D-pantoate and beta-alanine.
Biotin, also known as vitamin H or B7, is a water-soluble B-complex vitamin which is composed of an ureido (tetrahydroimidizalone) ring fused with a tetrahydrothiophene ring. A valeric acid substituent is attached to one of the carbon atoms of the tetrahydrothiophene ring.
