D-MANNOHEPTULOSE Usage And Synthesis

Description

D-Glucose is phosphorylated by glucokinase and three tissue-specific hexokinases to produce glucose-6-phosphate in humans. D-Mannoheptulose is a heptose that inhibits glucokinases and hexokinases from diverse organisms through competition with D-glucose (K_i = 0.25 mM). It blocks glucose oxidation and glucose-mediated insulin release from pancreatic islet cells. D-Mannoheptulose prevents the conversion of glucose to glucose-6-phosphate that can mediate the activation of the carbohydrate response element binding protein. By blocking glucose phosphorylation, D-mannoheptulose causes transient hyperglycemia in dogs when given at 1 g/kg but not at 8 mg/kg, although postprandial energy expenditure is increased at the lower dose.

White Solid

Uses

Mannoheptulose occurs naturally in avocado fruit. It is used for normalizing insulin levels and reducing weight.

Definition

ChEBI: D-keto-manno-heptulose is the open chain form of D-manno-heptulose.
