Question

why monosachrides are sweet whereas polysaccharides are not?​

Answer 1

$\huge{ \color{pink}{ \boxed{ \tt{ \color{orange}{Answer:}}}}}$

Our sweet-receptors bind to specific types of molecules, namely monosaccharides and disaccharides. Polysaccharides are not as sweet because they do not readily bind to the sweet-receptors on our tongue, as the other smaller molecules do!

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:

Monosachrides:

If you chew it for awhile, the Amylase enzyme in your saliva will eventually break down the starch into Monosaccharides and will taste sweet. Oligosaccharides are a short chain of Monosaccharides, like what you would find in beans.

Polysaccharides:

The polysaccharides do not bind to the taste receptors of the tongue as the monosaccharides.
