Vitamin B6: Key Roles
The question asks about the functions and active form of Vitamin B6. Let's analyze the given statements:
Statement 1: Role in Amino Acid Metabolism
Statement 1 claims Vitamin B6 acts as a cofactor for the metabolism of many amino acids. This is correct. Vitamin B6, specifically in its active form, is essential for numerous enzymatic reactions involving amino acids, including transamination, decarboxylation, and racemization.
Statement 2: Active Form Identification
Statement 2 identifies the active form in humans as pyridoxal 5-phosphate. This is also correct. Pyridoxal 5'-phosphate (PLP) is the principal coenzyme form of Vitamin B6 involved in the biochemical processes mentioned above.
Conclusion on Statements
Since both statement 1 and statement 2 are accurate descriptions of Vitamin B6's functions and form, the correct option includes both.
- Statement 1 is correct.
- Statement 2 is correct.
Therefore, the correct answer is that both statements are correct.
