Glucose

Definition

noun

A simple monosaccharide sugar that serves as the main source of energy and as an important metabolic substrate for most living things. Its chemical formula is: C6H12O6


Supplement

Glucose is a hexose sugar since it contains six carbon atoms, one of which is part of an aldehyde group, hence, is referred to as an aldohexose.

Glucose is one of the products of photosynthesis in plants and other photosynthetic organisms. In plants, glucose molecules are stored as repeating units of sugar (e.g. starch).

Glucose also serves as an important metabolic intermediate of cellular respiration. In animals, an excess of glucose is stored as glycogen.


Word origin: Greek gleukos = sweetness, glykys = sweet.

Related terms: Benedicts test for glucose, blood glucose, fasting glucose, glucose-6-phosphate.

Synonym: D-glucose, D-glucopyranose, grape sugar, corn sugar, dextrose, cerelose, starch syrup.
See also: monosaccharide.

does eating too much sweets cause diabetes?

... Some studies suggest that there might be some problem with beta cells also in type II diabetes, namely their in their ability to sense blood glucose levels. This might also contribute to the disease pathology. However, type II diabetes is still not related directly to the body's ability to ...

Re: Relationship between structure and function of glucoes

... to the ring. If there are any 1-6 bonds these cause branching -- these branches are common in starch. I wrote "Galactose is pure 1-4 α-bound glucose while starch is a polymer of the pure 1-4 β form" Oops. That should have been: Starch is pure 1-4 α-bound glucose while cellulose is a ...

Relationship between structure and function of glucoes

... What a confusion I caused! The difference in L-, D- properties would, in no way, originate from linking patterns (like in the case of α vs. β D-glucose). It would have to, as Jonmoulton speculated, originate from the fact that they are mirror images of each other. The reason for differences ...
