Metal Complexes of D-Glucosamine and its Derivatives. VII. Metal Complexes of D-Glucosaminic Acid

Chemical and Pharmaceutical Bulletin, 1966
Stability constants, log K1 and log K2, of complexes of D-glucosaminic acid with Cu2+, Ni2+, Pb2+, Zn2+, Co2+, Cd2+, and Mn2+were determined by pH titration method. Copper complexes were found to be the most stable and the contribution of OH groups of glucosaminic acid to the complex formation was observed.

Chitosanase may enhance anti-fungal defense responses in transgenic tobacco [PDF]

, 2003
Chitosanase is an enzyme, similar to chitinase, capable of hydrolyzing the β-1,4-linkages between N-acetyl-D-glucosamine and D-glucosamine residues in partially acetylated chitosan polymers found in fungal cell walls.

T Cell Glycoengineering to Modulate Immune‐Tumor Crosstalk: A Universal Non‐Genetic Strategy for Enhanced Tumor Immunotherapy

Advanced Science, EarlyView.
This study describes a T cell surface engineering strategy that integrates polymer materials with tumor immunology, aiming to achieve broad‐spectrum anti‐tumor applications of glycopolymer‐engineered T (G‐T) cells via non‐genetic modification. Glycopolymer engineering generally modulates immune‐tumor crosstalk through specific cell‐cell interactions ...

The hemostatic properties of chitosan in oral surgery

Biomedical and Biotechnology Research Journal, 2020
Chitosan (CS) belongs to the natural linear aminopolysaccharide family. It is formed by a repetition of D-glucosamine units (deacetylated units) and a smaller number of N-acetyl-D-glucosamine units. Their distribution is casual.

Long‐Term Active Rather than Passive Restoration Promotes Soil Organic Carbon Accumulation by Alleviating Microbial Nitrogen Limitation in an Extremely Degraded Alpine Grassland

Advanced Science, EarlyView.
Active restoration increases soil organic carbon stocks by reducing microbial nitrogen limitation. Nitrogen availability promotes particulate to mineral‐associated organic carbon conversion by reducing microbial carbon use efficiency. Passive restoration has no effect on soil organic carbon stocks.
