introduction
Monosaccharides consist typically 3 to 7 carbon atoms and are either as aldoses or ketosis , it contains aldehyde group or a ketone group
The simplest monosaccharide , aldose is glyceraldehyde , ketose is dihydroxyacetone. These simple sugars are knows as trioses because they contain three carbon units.
Stereoisomerism is an important characteristics of monosaccharides. Stereoisomers are the compounds that have same structural formula but they differ in their molecular arrangement.
A carbon is said to be asymmetric if it has four different groups attached to it. The number of asymmetric group determines the number of its possible isomers.
The D and L isomers are the mirror images of each other . the position of -H and -OH group on the carbon atom adjacent to the terminal primary alchoholcarbon determines wheter the sugar is D isomer or L isomer. If the -OH group is on right side it is D isomer and if it is on left side it is L isomer . naturally occurring monosaccharide are of D configuration.
If D and L isomers are present in equal concentration it is known as racemic mixture or DL mixture . such mixture does not exhibit any optical activity.
If two monosaccharides differ from each other in their structure at a single specific carbon they are referred as epimers. E.g. glucose and galactose are epimers with reference to C-4. the interconversion of epimers is known as epimerization and is catalysed by group of enzymes known as epimerases. All the heroes are widely distributed in nature and sweet in taste . glucose is a key monosaccharides in nature
These are some googled questions for monosaccharides which can be helpful
what are the 3 monosaccharides ?
3 main monosaccharides are glucose , fructose , and galactose . These 3 can be found anywhere and they are the primary monosaccharides and they combine with each other and create various forms . they can not be broken in simple sugar units.
