What is the Difference Between N-Acetyl-D-Glucosamine and N-Acetyl Glucosamine?

🆚 Go to Comparative Table 🆚

N-Acetyl-D-Glucosamine and N-Acetyl Glucosamine are both amide compounds derived from the monosaccharide glucose, but they have distinct differences.

N-Acetyl-D-Glucosamine:

  • It is an isomer of N-Acetyl Glucosamine.
  • It is highly abundant and plays a crucial role in building up the structure of the bacterial cell wall.

N-Acetyl Glucosamine:

  • It is the parent compound of N-Acetyl-D-Glucosamine.
  • It is derived from monosaccharide glucose and is an important amide compound.
  • It has two major isomers: the D isomer (N-Acetyl-D-Glucosamine) and the L isomer.
  • The D isomer is the most common and abundant form, while the L isomer is comparatively less abundant.

Both N-Acetyl-D-Glucosamine and N-Acetyl Glucosamine show stereoisomerism, meaning they have the same molecular formula but differ in their spatial arrangements. They are both amino sugars, with the hydroxyl group of glucose at position 2 substituted by an amino group and acetoamide, respectively. These compounds are believed to have a crucial role in the formation of glycosaminoglycans in cartilage.
