Product Introduction:

L-Phenylalanine is an aromatic amino acid with physiological activity. It is one of the amino acids that humans and animals cannot synthesize by themselves. It is one of the eight essential amino acids in the human body’s metabolism.

Most of the body is catalyzed by phenylalanine hydroxylase, where it is oxidized to tyrosine, and together with tyrosine, it synthesizes important neurotransmitters and hormones, and participates in the body’s sugar and fat metabolism.

L-Phenylalanine is an organic compound with a molecular formula of C9H11NO2 and a molecular weight of 165.19. It is a white crystalline powder. L-Phenylalanine powder is mainly used for biochemical research, culture medium preparation and nutritional research.
