Vitamin B6: Pyridoxal Phosphate

The video discusses pyridoxal phosphate, a cofactor essential for vitamin B6 metabolism. It explains how pyridoxal phosphate is transformed from pyridoxine and its critical role in enzyme functions, particularly in transaminases. The video also covers the chemical properties of pyridoxal phosphate, its involvement in various biochemical reactions, and its importance in nitrogen metabolism. The video concludes with a preview of future content on the mechanism of pyridoxal phosphate-dependent transamination.
