Final answer:
Pyridoxal phosphate facilitates the conversion of one type of amino acid to another through the process of transamination, which is catalyzed by transaminases that require pyridoxal phosphate as a coenzyme.
Step-by-step explanation:
Pyridoxal phosphate has the main function of converting one type of amino acid to another amino acid via transamination. Transamination is a biochemical process where an amino group from one amino acid is transferred to a keto acid to form a new amino acid. This reaction is catalyzed by enzymes known as transaminases or aminotransferases, which require pyridoxal phosphate as a coenzyme. It is essential for the synthesis of non-essential amino acids and plays a crucial role in nitrogen metabolism.
The correct answer to the question is c) Transamination.
