Abstract:
Sucrose is a substrate for starch biosynthesis, unloaded symplastically into the developing potato tubers. Sucrose is converted to glucose-6-phosphate in the cytosol and exported into the amyloplasts. Starch may be degraded either hydrolytically or phosphorolytically. Glucose and maltose are products of hydrolytic starch breakdown in the sprouting tubers. Glucose phosphates are products of the phosphorolytic activity, metabolized to glucose and fructose in cold-stored tubers. Development of molecular tools for assaying potato gene function provide opportunities to receive genetic progress in the sugar-starch potato breeding.

Carbohydrate Metabolism
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in the...
Overview of Carbohydrate Metabolism
Glucose transport into cells is facilitated by a family of transport proteins called GLUT (Glucose Transporters). GLUT4 is the primary glucose transporter for insulin-stimulated glucose...
