→Monosaccharides are further classified on the basis of number of carbon atoms and the functional group present in them.
→If a monosaccharide contains an aldehyde group it is known as an aldose and if it contains a keto group it is known as ketose.
→Number of carbon atoms constituting the monosaccharide is also introduced in the name. e.g. 3 carbon containing monosaccharide is known as triose and 4 carbon containing monosaccharide is known as tetrose.
→Different types of monosaccharide compounds are given below in table:

Carbon atoms	General term	Aldehyde	Ketone
3	Triose	Aldotriose	Ketotriose
4	Tetrose	Aldotetrose	Ketotetrose
5	Pentose	Aldopentose	Ketopentose
6	Hexose	Aldohexose	Ketohexose
7	Heptose	Aldoheptose	Ketoheptose
