Glucose is the most important carbohydrate fuel in the body. in the fed state, the majority of circulating glucose comes from the diet; in the fasting state, gluconeogenesis and glycogenolysis maintain glucose concentrations. very little glucose is found in the diet as glucose; most is found in more complex carbohydrates that are broken down to monosaccharides though the digestive process.
Glucose oxidase is widely used for the determination of free glucose in body fluids (medical testing), in vegetal raw material, and in the food industry.it also has many applications in biotechnologies, typically enzyme assays for biochemistry including biosensors in nanotechnologies. it was first isolated by detlev müller in 1928 from aspergillus niger..
Glucose-6-phosphate isomerase (gpi), alternatively known as phosphoglucose isomerase/phosphoglucoisomerase (pgi) or phosphohexose isomerase (phi), is an enzyme that in humans is encoded by the gpi gene on chromosome 19. this gene encodes a member of the glucose phosphate isomerase protein family. the encoded protein has been identified as a moonlighting protein based on its ability to perform.
