a simple sugar; a carbohydrate that cannot be broken down to simpler substances by hydrolysis. Subgroups include the aldoses
and the ketoses
A carbohydrate that cannot form any simpler sugar by simple hydrolysis, for example, pentoses, hexoses.
monosaccharide (mŏn′ə-săk′ə-rīd′, -rĭd)
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.
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.
