Carbohydrates or carbs

Carbohydrates are the energy reserves of the plants formed from photosynthetic reactions that accumulate in form of starch. When are ingested by the animals and combined with oxygen, they obtained energy for vital processes and emitted carbon dioxide to the atmosphere.

As its name suggests, carbohydrates are substances composed of hydrogen, carbon and oxygen. They are also known as glucose, which is one of the first compounds studied in this series.

Carbohydrates can be sugars composed of a single monomer such as glucose and fructose called monosaccharides, by two as lactose and sucrose called disaccharides, or large polymerised chains which include starch, cellulose and other compounds known as polysaccharides.
