What are monosaccharides?

Back

Monosaccharides are the simplest form of carbohydrates, consisting of single sugar molecules like glucose and fructose.

Front

What are polysaccharides and give two examples.

Back

Polysaccharides are complex carbohydrates made up of long chains of monosaccharides. Examples include starch and cellulose.
