| Outline of Final Research Achievements |
Chitin is the most abundant marine biomass, which is contained in crab and shrimp shells. Chitin is a polymer consisting of N-acetylglucosamine (NAG) units, thus characteristically containing nitrogen atoms. This compound is a potential renewable resource for the production of nitrogen-containing chemicals, but the recalcitrance of chitin has strongly limited use of the derivatives such as NAG in industry and daily life.
In this study, co-workers and I found that mechanical force and catalysts synergistically depolymerize chitin to produce NAG in a good yield. In addition, NAG was converted to useful chemicals such as N-acetyl-monoethanolamine and a derivative of standard amino acid, N-acetylglycine.
