In cells D-glucose 6-phosphate (G6P) is generated when glucose is phosphorylated by hexokinase or glucokinase or by the conversion of glucose-1-phosphate by phosphoglucomutase during glycogenolysis. G6P lies at the beginning of both glycolysis and the pentose phosphate pathways. It also can be stored as glycogen when blood glucose levels are high.

Geoside is a natural compound isolated from stevia rebaudiana.

Protocatechuic acid 3-O-β-D-glucopyranoside is produced from the hairy root culture of Lobelia sessilifolia supplemented with Protocatechuic acid. Protocatechuic acid 3-O-β-D-glucopyranoside is potent for the production of new phenol glycosides which could be applied in natural chemistry, biochemistry and pharmacognosy
