Pathway Description
Starch and Sucrose Metabolism
Arabidopsis thaliana
Metabolic Pathway
Sucrose is common natural plant produced disaccharide composed of one glucose and one fructose, its molecular formula is C12H22O11. Starch is a Homo-polymeric carbohydrate composed of glucose units joined by glycosidic bonds. it is used as energy storage and converted for use when glucagon stimulates PKA for increase in gluconeogenesis activity, therefore increase the conversion of glycogen to glucose units. Glucose 1 phosphate is a intermediate of this pathway, it can be converted to Glucose 6 phosphate for glycolysis use when stimulated by Insulin. These sugars can also go enter nucleotide and amino acid synthesis pathways through transamination reactions
