Energy carbohydrate

Potatoes have been valued around the world for centuries because they are an easily cultivated, easily prepared and readily assimilated source of carbohydrate energy. The ease with which potatoes are digested has, however, become a double-edged sword, as the interrelated epidemics of metabolic syndrome and type 2 diabetes become global crises linked to rising obesity. At the same time as carbohydrates have been blamed for obesity, glucose intolerance has become recognized as a core feature of the metabolic syndrome and type 2 diabetes (Seidell, 2000). 

Relevance to potatoes Potatoes have thin cell walls so are not rich in NSPs. They are a valuable source of carbohydrate energy, but would not on their own provide enough dietary fiber to meet daily requirements. Increasing RS levels partially compensates for the low dietary fiber content of potatoes.

In mammalian cells, glucose is the most abundant carbohydrate energy source. It is metabolized in all cells as a glycolytic fuel and is stored in liver and muscle as the polymer glycogen. But certain cells have the enzymes to catalyze the synthesis of glucose under certain conditions. The requirements are (1) the availability of specific carbon skeletons (carbon backbone structures of various types), (2) energy, in the form of ATP, necessary to accomplish the sequence of reactions, and (3) the enzymes to catalyze reactions of the sequence.

PGA represents 3-phosphoglyceric acid. Six moles of NADPH + are required to provide the 12 electrons required to reduce three moles of carbon initially in the form of CO2 to the level of carbohydrate. Energy provided by the hydrolysis of ATP (not shown) is required to drive the overall process. 

Starch is a plant polysaccharide that we encounter in our food, but we in fact manufacture a very similar substance ourselves in our liver and in our muscles we have our own carbohydrate energy store, glycogen. This is closely similar to plant amylopectin, with a branched, tree-like molecule, the only difference being that glycogen is more highly branched.
