what are carbohydrates made of
Carbohydrates Carbohydrates (also called saccharides) are molecular compounds made from just three elements: carbon, hydrogen and oxygen. Monosaccharides (e.g. glucose) and disaccharides (e.g. sucrose) are relatively small molecules. They are often called sugars.Other carbohydrate molecules are very large (polysaccharides such as starch and cellulose). Carbohydrates are: 1  a source of energy for the body e.g. glucose and a store of energy, e.g. starch in plants.hey are often called sugars. Other carbohydrate molecules are very large (polysaccharides such as starch and cellulose). Carbohydrates are: 1  a source of energy for the body e.g. glucose and a store of energy, e.g. starch in plants.
Carbohydrates are made of a carbon backbone or ring, combined with  hydrogen and hydroxyl groups in equal proportions (water molecules  on a carbon backbone).    Lipi â¦ ds are made of a long carbon chain with a carboxyl group (COOH)  at one end. Understanding What Simple Sugars Are Fructose, glucose, refined table sugar, and high-fructose corn syrup are all examples of simple sugars. 2  These are simple carbohydrates that consist of one or two sugars.
