Detailed explanation-1: -Ribose is an aldopentose (a monosaccharide containing five carbon atoms that, in its open chain form, has an aldehyde functional group at one end). In the conventional numbering scheme for monosaccharides, the carbon atoms are numbered from C1’ (in the aldehyde group) to C5’.

Detailed explanation-2: -Examples of monosaccharides include glucose (dextrose), fructose (levulose), and galactose. Monosaccharides are the building blocks of disaccharides (such as sucrose and lactose) and polysaccharides (such as cellulose and starch).

Detailed explanation-3: -Ribose is an important biological molecule present in all living organisms in one or another form. It is a monosaccharide with 5 carbons having an aldehydic group. L-ribose and D-ribose are two optical isomers that can either form a pentagonal or hexagonal ring in aqueous solution.
