1,5-anhydro-D-fructose Anthracobia melaloma i.e. 1,5-anhydro-D-arabino-hex-2-ulose. This enzyme catalyses one of the steps in the anhydrofructose pathway, which leads to the degradation of glycogen and starch via 1,5-anhydro-D-fructose 1,5-anhydro-4-deoxy-D-glycero-hex-3-en-2-ulose + H2O i.e.ascopyrone M ir
