pyridoxal phosphate
Active B6 form
Pyridoxal phosphate is the active form of vitamin B6, serving as a coenzyme in numerous metabolic reactions—particularly those involving amino acids.
It participates in transamination, decarboxylation, and other transformations essential to protein metabolism and neurotransmitter synthesis.
Often abbreviated PLP.
Pyridoxal phosphate deficiency can cause neurological symptoms.
