For many monosaccharides (including glucose), the cyclic forms predominate, in the solid state and in solutions, and therefore the same name commonly is used for the open- and closed-chain isomers. Thus, for example, the term "glucose" may signify glucofuranose, glucopyranose, the open-chain form, or a mixture of the three.
Monosaccharides are carbohydrates in the form of simple sugars. Like disaccharides , they are sweet, water soluble and crystalline . The main article for this category is Monosaccharides .
The classic example of a dehydration reaction is the Fischer esterification, which involves treating a carboxylic acid with an alcohol to give an ester RCO 2 H + R′OH ⇌ RCO 2 R′ + H 2 O. Often such reactions require the presence of a dehydrating agent, i.e. a substance that reacts with water.
Disaccharides are formed when two monosaccharides, or two single simple sugars, form a bond with removal of water. They can be hydrolyzed to yield their saccharin building blocks by boiling with dilute acid or reacting them with appropriate enzymes. [6] Examples of disaccharides include sucrose, maltose, and lactose.
A diose is a monosaccharide containing two carbon atoms. Because the general chemical formula of an unmodified monosaccharide is (C·H 2 O) n, where n is three or greater, it does not meet the formal definition of a monosaccharide. [1] However, since it does fit the formula (C·H 2 O) n, it is sometimes thought of as the most basic sugar. [2]
Monosaccharide nomenclature is the naming system of the building blocks of carbohydrates, the monosaccharides, which may be monomers or part of a larger polymer. Monosaccharides are subunits that cannot be further hydrolysed in to simpler units.
With few exceptions, all monosaccharides are variations on the empirical formula (CH 2 O) n, where n typically ranges from 3 to 7 . [3] Common examples include glucose, ribose, and deoxyribose. monosomy The abnormal and frequently pathological presence of only one chromosome of a normal diploid pair. It is a type of aneuploidy.

An example of a mountain lake ecosystem. Hydrobiology is the science of life and life processes in water. Much of modern hydrobiology can be viewed as a sub-discipline of ecology but the sphere of hydrobiology includes taxonomy, economic and industrial biology, morphology, and physiology. The one distinguishing aspect is that all fields relate ...
