monosaccharide

 [mon″o-sak´ah-rīd]
a simple sugar; a carbohydrate that cannot be broken down to simpler substances by hydrolysis. Subgroups include the aldoses and the ketoses.

mon·o·sac·cha·ride

(mon'ō-sak'ă-rīd),
A carbohydrate that cannot form any simpler sugar by simple hydrolysis, for example, pentoses, hexoses.
Synonym(s): monose

monosaccharide

(mŏn′ə-săk′ə-rīd′, -rĭd)
n.
Any of several carbohydrates, such as tetroses, pentoses, and hexoses, that cannot be broken down to simpler sugars by hydrolysis. Also called simple sugar.

monosaccharide

Simple sugar A monomer of a more complex carbohydrate Examples Glucose, fructose, galactose. Cf Disaccharide, Polysaccharide.

mon·o·sac·cha·ride

(mon'ō-sak'ă-rīd)
A carbohydrate that cannot form any simpler sugar by simple hydrolysis; e.g., pentoses, hexoses.

monosaccharide

The simplest form of sugar. Monosaccharides are classified by the number of carbon atoms in the molecule. They may thus be trioses, tetroses, pentoses, hexoses, etc. The commonest monosaccharide in the body is GLUCOSE, which is a hexose, with six carbons.

monosaccharide

a carbohydrate MONOMER, a simple sugar with the formula (CH2O)n, e.g. C6H12 O6 glucose and fructose. See Fig. 224 . Such carbohydrates are generally white, crystalline solids, with a sweet taste, and are usually soluble in water. The carbon chain forming the backbone of such sugars can be of varying lengths. Some monosaccharides contain only three carbons (‘triose’ types such as glyceraldehyde) others contain five carbons (‘pentose’ types such as the deoxyribose sugar of DNA), but those with six carbons (‘hexose’ types such as glucose) are the most important since they can be joined together by CONDENSATION REACTIONS (loss of water) to form DISACCHARIDES and POLYSACCHARIDES.

Carbohydrates are complex sugar molecules composed of two to 10 simple sugar molecules.
With her mother's blessing (and a $50,000 charge to her credit card), Lazzari took off her junior year of high school to study independently while focusing full time on Simple Sugars.

In contrast, a diet that includes complex carbohydrates - such as whole grains, fruits and vegetables - results in a more gradual increase in blood sugar, because the body requires time to break down these complex carbohydrates into simple sugars. The result: a steady supply of sugar to the bloodstream, so the body is more efficient.
