Sugars/carbohydrates metabolic processes

The discovery of enzyme systems by which D-glucose could be isomerized directly to D-fructose was a key factor in the development of commercial-scale isomerization-processes. These direct systems were developed from fundamental studies of carbohydrate metabolism, in which was identified for the first time an enzyme that catalyzes the isomerization of an unsubstituted sugar, namely, the isomerization of D-erythrose to D-g/ycero-tetrulose.31... 

Carbohydrates have several essential functions in living organisms. One of the most important is the role of carbohydrates in the metabolic process in which sugar molecules are... 

The relationship, if any, between the secondary metabolism of L-phenylalanine and carbohydrate degradation during brown-rot wood decay processes has not yet been determined. However, we suspect that the secondary metabolism of this aromatic amino-acid plays an important role in converting monomeric sugars to nitrogen-free metabolites (Shimada, M., and Takahashi, M., In Handbook of Wood and Cellulosic Materials Hon,...
