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.

Co2 from respiration-Sugars vs Fats

So more co2 is produced from glucose than from fat; correct? Say you had two 2000cal diet one being 60%carb and the other 30%carb, how much more co2 would you produce on 60% carb? Thank you

Lac operon and bioinformatics

I am trying to incorporate bioinformatics regarding the lac operon. Any ideas as to how? I'm looking at the e. coli cells changing from a glucose medium to a lactose medium?

Energy; respiration and photosynthesis

Hello Members, Living cells respire. Aerobic respiration is the chemical reaction used to release energy from glucose. It is called aerobic because oxygen from the air is also needed. Plant cells respire, just as animal cells do. If they stop respiring, they will die. Remember ...

Why ?

They are stored that way - only glucose is stored as glycogen. Whether amino acids get "stored" depends upon how your define the term, and lipids are definitely stored.
