Vitamin b6 is a watersoluble vitamin and is part of the vitamin B complex group.  Several forms  of the vitamin are known, but pyridoxal phosphate (PLP) is the active  form  and is a  cofactor  in many reactions of amino acid metabolism, including transamination, deamination, and decarboxylation. PLP also is necessary for the enzymatic reaction governing the release of glucose from glycogen

List of Vitamin B Complex Powder
Vitamin B1 thiamine A coenzyme in the catabolism of sugars and amino acids.

Vitamin B2 riboflavin A precursor of cofactors called FAD and FMN, which are needed for flavoprotein enzyme reactions, including activation of other vitamins

Vitamin B3 niacin (nicotinic acid), nicotinamide riboside A precursor of coenzymes called NAD and NADP, which are needed in many metabolic processes.

Vitamin B5 pantothenic acid A precursor of coenzyme A and therefore needed to metabolize many molecules.

Vitamin B6 pyridoxine, pyridoxal, pyridoxamine A coenzyme in many enzymatic reactions in metabolism.

Vitamin B7 biotin A coenzyme for carboxylase enzymes, needed for synthesis of fatty acids and in gluconeogenesis.

Vitamin B9 folate A precursor needed to make, repair, and methylate DNA; a cofactor in various reactions; especially important in aiding rapid cell division and growth, such as in infancy and pregnancy. Synthetic folate is known as folic acid.

Vitamin B12 various cobalamins; commonly cyanocobalamin or methylcobalamin in vitamin supplements A coenzyme involved in the metabolism of every cell of the human body, especially affecting DNA synthesis and regulation, but also fatty acid metabolism and amino acid metabolism.
