Introduction：Dextrose (C6H12O6), a simple sugar (monosaccharide), is an important carbohydrate in biology. Cells use it as a source of energy and a metabolic intermediate. Dextrose is one of the main products of photosynthesis and starts cellular respiration. Starch and cellulose are polymers derived from the dehydration of Dextrose.
Dextrose can adopt several different structures, but all of these structures can be divided into two families of mirror-images (stereoisomers). Only one set of these isomers exists in nature, those derived from the "right-handed form" of Dextrose, denoted D- Dextrose .
Chemical Properties: White crystalline powder, Watery odorless colorless liquid. Denser than water and soluble in water. Hence sinks in and mixes with water.
Molecular formula: C6H12O6
Molecular weight: 180.16
CAS Number:50-99-7
Stability: Stable. Substances to be avoided include strong oxidizing agents. Combustible.
Function:
As an energy source:
Dextrose is a ubiquitous fuel in biology. It is used as an energy source in most organisms, from bacteria to humans. Use of glucose may be by either aerobic respiration, anaerobic respiration, or fermentation. Carbohydrates are the human body's key source of energy, through aerobic respiration, providing approximately 3.75 kilocalories (16 kilojoules) of food energy per gram.
Dextrose is a primary source of energy for the brain, and hence its availability influences psychological processes. When Dextrose is low, psychological processes requiring mental effort (e.g., self-control, effortful decision-making) are impaired.
Dextrose in glycolysis:
Use of Dextrose as an energy source in cells is via aerobic or anaerobic respiration.
The major reason for the immediate phosphorylation of Dextrose by a hexokinase is to prevent diffusion out of the cell.
As a precursor:
Dextrose is critical in the production of proteins and in lipid metabolism. In plants and most animals, it is also a precursor for vitamin C (ascorbic acid) production. It is modified for use in these processes by the glycolysis pathway.
Dextrose is used as a precursor for the synthesis of several important substances.
Industrial use: In industry, glucose is used as a precursor to make vitamin C in the Reichstein process, to make citric acid, gluconic acid, bio-ethanol, polylactic acid, sorbitol.
