What combines together to form a disaccharide?

Prefixes: mono, di, tri, tri, poly, and many

Firstly, let's define a disaccharide (saccharide is another word for sugar).

The word "monosaccharide" literally means "one sugar" (single sugar) because the prefix "mono-" means "one." Monosaccharides, such as glucose, are the most basic type of sugar and cannot be broken down any further.

A disaccharide is a compound that is formed when two simple molecules or monosaccharides are joined together. The word "disaccharide" literally means "two sugars" (double sugars) because the prefix "di-" means "two."

Disaccharide examples include maltose, which is glucose plus glucose, sucrose, which is glucose plus fructose, and lactose, which is glucose plus galactose.

A molecule of water is eliminated as a bond forms between two monosaccharides in a process known as dehydration synthesis reaction, which unites the two monosaccharides to form a disaccharide.
