Answer 2

Answer:      

Monosaccharides are sweet in nature but polysaccharides are not because the polysaccharides do not bind to the taste receptors of the tongue as the monosaccharides.  

Explanation:

The monosaccharides have a particular structure that binds to the taste receptors of the tongue whereas in a polysaccharide these taste receptors are entangled or joined together to form a whole polysaccharide unit. Another important aspect is that a polysaccharide is a huge moiety that is to be recognised by the taste buds of the tongue.
