gluco-, gluc-, gluk-

(Greek: sweet, sweetness)

An intracellular deficiency of glucose.
An isomer of glucose that is found in honey and sweet fruits; dextrose (dextrorotatory form of glucose found naturally in animal and plant tissue and derived synthetically from starch).
1. Giving rise to or producing glucose.
2. Tending to produce a pyruvate residue in metabolism which undergoes conversion to a carbohydrate (as glucose) and is eventually stored as a complex carbohydrate (as glycogen).
A medical term meaning that blood contains the sugar glucose; glycaemia.
1. Having the ability to activate glucose, especially by breaking down stored glycogen so as to increase glucose concentrations in the blood.
2. Activating sugar so as to maintain the sugar level of the blood.
3. Tending to mobilize glucose; usually evidenced by a reduction of the glycogen stores in the tissues to produce an increase in the concentration of glucose circulating in the blood.
glucolysis, glucolytic
1. The conversion of a monosaccharide (generally glucose) to pyruvate via the glycolytic pathway.
2. The anaerobic enzymatic conversion of glucose to the simpler compounds lactate or pyruvate, resulting in energy stored in the form of adenosine triphosphate (ATP), as occurs in muscle; it differs from respiration in that organic substances, rather than molecular oxygen, are used as electron acceptors.
An abnormally small concentration of glucose (sugar) in circulating blood, i.e., less than the minimum of the normal range; hypoglycemia.
1. A simple sugar produced in plants by photosynthesis and in animals by the conversion of carbohydrates, proteins, and fats. The commonest form, dextrose, is used by all living organisms.
2. A syrup containing dextrose, maltose, dexrin, and water that is obtained from starch and used in food manufacture and in alcoholic fermentation.
The d-isomer (also referred to as fruit sugar, levoglucose, levulose, and d-arabino-2-hexulose) is a 2-ketohexose that is physiologically the most important of the ketohexoses and one of the two products of sucrose hydrolysis; it is metabolized or converted to glycogen in the absence of insulin; fructose.
1. A sweet white crystalline substance, metameric with pyrogallol, and obtained by the decomposition of phloretin, and from certain gums, as catechu, kino, etc. It belongs to the class of phenols.
2. Also called, phloroglucinol: 1,3,5-benzenetriol. A trinitrobenzene derivative with antispasmodic properties that is used primarily as a laboratory reagent.
