应用
Diacetylchitobiose/Chitobiose, a dimer of β(1,4) linked N-acetyl-D glucosamine, is used as an alternative source of N-acetylglucosamine by some bacteria. It is used in fermentation research to study, differentiate and characterize chitobiose transporter systems and enzymes such as β-N-acetylglucosaminidase(s) and chitobiose phosphorylase(s).

生化/生理作用
In chitinolytic bacteria, such as Vibrio, Streptomyces and Serratia, N,N′-Diacetylchitobiose (GlcNAc2) is not only a major breakdown product of chitinase, but it is also the smallest substance that induces chitinase production. It can also be utilized as a carbon source by E. coli, which does not express chitinases, but is exposed to GlcNAc2 produced by intestinal chitinolytic bacteria. In most organisms, the uptake of GlcNAc2 occurs via the phosphoenolpyruvate:glycose phosphotransferase system (PTS). GlcNAc2 has also been used as a substrate or inhibitor to study the activity of glycolytic enzymes.
