This means that when you’re stressed, there is less B6 available to perform its other important functions. For instance, vitamin B6 is essential to the formation of the feel-good neurotransmittersGABA,serotonin, anddopamine. GABA GABA (gamma-aminobutyric acid) is the brain chemical associated wit...
63、sfer of carboxy groups by transcarboxylases and with decarboxylations. The biotin is bound to the protein by an amide linkage through its carboxyl group to that of the of the amino group of lysine. Activation of carbon dioxide proceeds by the following reaction with formation of a biotin...
Homeostasis can be defined, then, as the ability of a living organism to maintain its structure and function intact, separate from and invulnerable to the forces of its environment. The maintenance of homeostasis is highly complex, requiring many series of chemical reactions, distinct and yet inter...
