what are monosaccharides and dissaccharides?

Answer 1

They are sugar compounds.
Monosaccharides have a single 5 or 6-carbon ring, whereas disaccharides are double rings. Disaccharides can be chemically separated into two monosaccharides.

For example, table sugar or "sucrose" is a disaccharide. It can be separated into glucose and fructose, which are monosaccharides.

Monosaccharides are the chemically the simplest of sugars, and are sometimes known as "simple sugars".

Answer 2

A saccharide is also called a simple sugar molecule. There are several different types of saccharides, including familiar names like glucose and fructose. Some sugars are made of saccharides that stay separate; they're called monosaccharides. (Mono- means one.) A monosaccharide is the same thing as a saccharide. Other sugars are made of two saccharides linked together; they're called disaccharides. (Di- means two.) If they're made of more than two saccharides, they're called polysaccharides (poly-means many).

Answer 3

Both are simple sugars
monoSaccharides= glucose, fructose
disaccharide= maltose, lactose
