In blood Pl PLP Pyridoxine kinase

Alkaline phosphatase

Sensitive to high temperature

Transamination

Deamination

Decarboxylation

Desulfuration

Production of Niacin

Glycogenolysis

Healthy skin

Metabolism and formation RBCs

In nervous and immune system

Maintain blood glucose level

Convert blood carbohydrate to glycose

Reaction type Example

Deamination Serine → pyruvate + NH3 Threonine → propionic acid + NH3

Decarboxylation glutamic → ϒ amino butyric acid (GABA)

-amino ẞ-keto adipic → ϒ amino levulonic acid

desulfuration cysteine → pyruvic acid
