A molecule containing one unit of sugar is called a ?

A molecule that comprises a single sugar unit and usually has the formula C6H12O6. While some monosaccharides have the same molecular formula, their differences in structural formula (the way in which their atoms are arranged within the molecule) is what creates their differences in properties.

Carbohydrate

Explanation: Carbohydrates containing one or two sugar units are referred to as simple carbohydrates. Carbohydrates containing many sugar molecules are called complex carbohydrates Simple carbohydrates.

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.
