Water-soluble B Vitamins are important cofactors in cell metabolism. Two water-soluble vitamins with clinical relevance are Vitamins B1 and B6. Thiamine Diphosphate (TDP) is the biologically active form of Vitamin B1 and is required for various metabolic functions. Prolonged deficiency can cause Beriberi, a debilitating neurological disease. Pyridoxal 5- phosphate (PLP) is the biologically active form of Vitamin B6 and is a coenzyme for a number of transamination reactions. It plays critical roles in chronic disease and pro-inflammatory response. Additionally, both Vitamin B6 and B1 have also been linked to increased survival rates in the elderly.
