N-Acetyl Glucosamine
Glucosamine is found in three major forms: glucosamine sulfate, glucosamine hydrochloride and n-acetyl glucosamine. These act differently in the body. Glucosamine (as a supplement) has been studied for treating wear-and-tear of joints because glucosamine is a major component of cartilage. Certain levels of glucosamine are needed in the blood to produce hyaluronic acid (one substance essential to heal skin injuries). Because of this property, glucosamine plays a major role in the healing of surgeries.[1] It is one of five glyconutrients found in breast milk. It can also be found in shiitake mushrooms. Glucosamine can be biosynthesized from glucose.[2]
N-Acetyl Galactosamine
N-acetyl galactosamine is derived from glucosamine.[2] It is the terminal glyconutrient on the antigen of blood group A and is responsible for full serological activity.[3] N-acetyl galactosamine is essential for intercellular communication and can be found in sensory nerve structures of animals.[4]
