In
enzymology
Enzymes () are proteins that act as biological catalysts by accelerating chemical reactions. The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products. A ...

β-D-glucose 1-phosphate, and one
product,
β-D-glucose 6-phosphate.
This enzyme belongs to the family of
isomerases, specifically the phosphotransferases (phosphomutases), which transfer phosphate groups within a molecule. The
systematic name of this enzyme class is beta-D-glucose 1,6-phosphomutase. This enzyme participates in
starch and sucrose metabolism
Starch or amylum is a polymeric carbohydrate consisting of numerous glucose units joined by glycosidic bonds. This polysaccharide is produced by most green plants for energy storage. Worldwide, it is the most common carbohydrate in human diets, ...
