Which of the following is incorest regarding monosaccharides? b) smallest monosaccharides are composed of three carbons. d) must be either ether or ester a) aldoses and ketoses c) exist in many isomeric forms e) two monosaccharides can combine to form a disaccharide

Must be either ether or ester.

Explanation:

The incorrect statement is that the monosaccharides must ether or esters.

The main and compulsory functional group in a monosaccharide are aldehyde and ketones.

The other statements are true

1) smallest monosaccharides are composed of three carbons: the smallest monosaccharide is glyceraldehyde.

a) aldoses and ketoses : they have either aldehyde group or ketone group

example: glucose is aldose and fructose if keotse

c) exist in many isomeric forms: there can be many arrangement on chiral carbons thus many stereoisomers are possible

e) Two monosaccharides can combine to form a disaccharide: yes for example glucose combines with fructose to give sucrose.

lol idk man i guess u gotta ask bill nye the science guy
