  1. glucosenoun

    a monosaccharide sugar that has several forms; an important source of physiological energy


  1. glucosenoun

    A simple monosaccharide (sugar) with a molecular formula of CHO; it is a principle source of energy for cellular metabolism.

  2. Etymology: from related to ; note: -ose comes from glucose, not the other way round


  1. Glucose

    Glucose is a simple sugar with the molecular formula C6H12O6. Glucose is overall the most abundant monosaccharide, a subcategory of carbohydrates. Glucose is mainly made by plants and most algae during photosynthesis from water and carbon dioxide, using energy from sunlight, where it is used to make cellulose in cell walls, the most abundant carbohydrate in the world.In energy metabolism, glucose is the most important source of energy in all organisms. Glucose for metabolism is stored as a polymer, in plants mainly as starch and amylopectin, and in animals as glycogen. Glucose circulates in the blood of animals as blood sugar. The naturally occurring form of glucose is d-glucose, while its stereoisomer l-glucose is produced synthetically in comparatively small amounts and is less biologically active. Glucose is a monosaccharide containing six carbon atoms and an aldehyde group, and is therefore an aldohexose. The glucose molecule can exist in an open-chain (acyclic) as well as ring (cyclic) form. Glucose is naturally occurring and is found in its free state in fruits and other parts of plants. In animals, glucose is released from the breakdown of glycogen in a process known as glycogenolysis. Glucose, as intravenous sugar solution, is on the World Health Organization's List of Essential Medicines. It is also on the list in combination with sodium chloride.The name glucose is derived from Ancient Greek γλεῦκος (gleûkos, "wine, must"), from γλυκύς (glykýs, "sweet"). The suffix "-ose" is a chemical classifier, denoting a sugar.


  1. glucose

    Glucose is a simple sugar (monosaccharide) with the chemical formula C6H12O6. It is the primary source of energy for most living organisms, being utilized by cells to produce ATP (adenosine triphosphate) through metabolic processes like glycolysis and cellular respiration. Glucose is naturally occurring and can be found in foods containing carbohydrates such as fruits, vegetables, grains, and honey. Moreover, it is also produced during photosynthesis in plants. In the field of medicine, blood glucose levels are essential indicators of certain conditions like diabetes.

Webster Dictionary

  1. Glucosenoun

    a variety of sugar occurring in nature very abundantly, as in ripe grapes, and in honey, and produced in great quantities from starch, etc., by the action of heat and acids. It is only about half as sweet as cane sugar. Called also dextrose, grape sugar, diabetic sugar, and starch sugar. See Dextrose

  2. Glucosenoun

    any one of a large class of sugars, isometric with glucose proper, and including levulose, galactose, etc

  3. Glucosenoun

    the trade name of a sirup, obtained as an uncrystallizable reside in the manufacture of glucose proper, and containing, in addition to some dextrose or glucose, also maltose, dextrin, etc. It is used as a cheap adulterant of sirups, beers, etc

  4. Etymology: [Gr. sweet. Cf. Glycerin.]


  1. Glucose

    Glucose is a simple monosaccharide found in plants. It is one of the three dietary monosaccharides, along with fructose and galactose, that are absorbed directly into the bloodstream during digestion. An important carbohydrate in biology, cells use it as the primary source of energy and a metabolic intermediate. Glucose is one of the main products of photosynthesis and fuels for cellular respiration. Glucose exists in several different molecular structures, but all of these structures can be divided into two families of mirror-images. Only one set of these isomers exists in nature, those derived from the "right-handed form" of glucose, denoted D-glucose. D-glucose is sometimes referred to as dextrose, although the use of this name is strongly discouraged. The term dextrose is derived from dextrorotatory glucose. This name is therefore confusing when applied to the enantiomer, which rotates light in the opposite direction. Starch and cellulose are polymers derived from the dehydration of D-glucose. The other stereoisomer, called L-glucose, is hardly ever found in nature. The name "glucose" comes from the Greek word glukus, meaning "sweet". The suffix "-ose" denotes a sugar.
