How Is Glucose Produced?
Your body thrives on glucose, which is the sugar it uses to synthesize energy. Carbohydrates supply glucose and other sugars that are converted into glucose. But it's such a vital source of energy that the body has a back-up system called gluconeogenesis. This metabolic pathway produces new glucose from noncarbohydrate sources. Video of the Day Carbohydrates are made from molecules of sugar connected together. Simple sugars consist of one to three sugar molecules, while starches contain hundreds to thousands of molecules, reports Colorado State University. The small intestine only absorbs single sugar molecules, which is why digestive enzymes break carbs down into the three monosaccharides: glucose, galactose and fructose. The monosaccharides travel to the liver, where glucose is generated when the liver turns galactose and fructose into glucose. The liver may send glucose into the bloodstream, where it’s transported to cells that need it for energy. If blood levels of glucose are high enough to meet your energy needs, the liver stores glucose by turning it into glycogen or fat. New Glucose Synthesis When the body produces glucose from something other than carbohydrates, the proc Continue reading >>
