Pyridoxal phosphate (PLP, pyridoxal 5'-phosphate, P5P) is a coenzyme, the active form of vitamin B6. Pyridoxal 5′-phosphate (PLP) is used as a cofactor for a wide range of enzymes including mitochondrial cysteine desulfurase, cystathionine γ-synthase (CGS), ornithine 4,5-aminomutase (OAM), and d-serine dehydratase. The versatility of PLP arises from its ability to covalently bind the substrate, and then to act as an electrophilic catalyst, thereby stabilizing different types of carbanionic reaction intermediates. PLP acts as a coenzyme in all transamination reactions, in various beta-elimination reactions, in the condensation reaction in heme synthesis.

Creatinolfosfate (or creatinol-O-phosphate, or COP) possesses anti-ischemic and anti-arrhythmic activities associated with improved ionic balance and heart performance. This compound exerts its cardioprotective effect by action on anaerobic glycolysis. The results of the toxicological studies showed that creatinolfosfate didn’t have side effects.

Sodium glycerol 2-phosphate (Disodium beta-glycerophosphate) is used for the preparation of thermo-sensitive chitosan hydrogen as a scaffold to construct tissue engineered injectable nucleus pulposus (NP). Since Sodium glycerol 2-phosphate (6 g/day) reduced the lithogenic index of bile in human subjects with cholesterol gallstones in a short-term study and facilitated dissolution of cholesterol gallstones in mice, Sodium glycerol 2-phosphate may have potential to help dissolve cholesterol gallstones in man. Sodium glycerol 2-phosphate is an alkaline phosphate inhibitor. Sodium β-glycerophosphate pentahydrate is used as a phosphatase inhibitor. It promotes bone matrix mineralization while delivering to osteoblasts by providing a source of phosphate ions. It is used in the development of hydrogels and scaffolds, which finds applications in tissue engineering and cell growth. It is used as an additive in isolation mediums by providing phosphate ions to isolate. It is utilized to promote mineralization in vitro by modulating bone cell metabolic activity.

Phosphoric acid, also known as orthophosphoric acid, is used in dentistry and orthodontics to clean and roughen the surfaces of teeth where dental appliances or fillings will be placed. In addition, this acid is a part of product ProcalAmine, which is indicated for peripheral administration in adults to preserve body protein and improve nitrogen balance in well-nourished, mildly catabolic patients who require short-term parenteral nutrition. In combination with dextrose (glucose) and levulose (fructose), phosphoric acid relieves nausea due to upset stomach from intestinal flu, stomach flu, and food or drink indiscretions. In addition, homeopathic product, Brain power contains also phosphoric acid and this product is used to temporarily relieve symptoms of general physical weakness and listlessness, including: fatigue; sore muscles & joints; dry skin; absence of sexual desire; occasional sleeplessness.
