pyridoxal phosphate has been researched along with Aging in 59 studies
Pyridoxal Phosphate: This is the active form of VITAMIN B 6 serving as a coenzyme for synthesis of amino acids, neurotransmitters (serotonin, norepinephrine), sphingolipids, aminolevulinic acid. During transamination of amino acids, pyridoxal phosphate is transiently converted into pyridoxamine phosphate (PYRIDOXAMINE).
pyridoxal 5'-phosphate : The monophosphate ester obtained by condensation of phosphoric acid with the primary hydroxy group of pyridoxal.
Aging: The gradual irreversible changes in structure and function of an organism that occur as a result of the passage of time.
