摘要
4-Hydroxy-2(or 5)-ethyl-5(or 2)-methyl-3(2H)-furanone (HEMF) is a character-impact compound of shoyu (Japanese soy sauce). This paper describes the biosyntheses of HEMF by yeasts. As precursors of the compound, intermediates of the pentose-phosphate cycle such as D-ribulose 5-phosphate barium salt, the combination of D-xylulose 5-phosphate sodium salt and D-ribose 5-phosphate, and D-sedoheptulose 7-phosphate barium salt are discussed. The pentose-phosphate cycle is necessary for yeasts to produce HEMF.
