Biological molecules are any molecules that are found in living organisms, from smaller molecules like primary metabolites, secondary metabolites and natural products to large macromolecules like proteins, lipids, nucleic acids and polysaccharides. Biological molecules, also referred to as biomolecules, are present in the chemistry of every life form on Earth. Regardless of how advanced an organism is, only a few groups of carbon-based compounds can be found in every living thing. Each of the biomolecules have their own roles to act on, making them all important in individual ways.
Carbohydrates can be split into simple and complex groups but all of them are formed from the same elements: carbon, oxygen and hydrogen. All carbohydrates are important as they do different jobs within the body, from providing support for structures such as cell walls and plasma membranes to storing and transporting energy. Carbohydrates are sugars and can be split into monosaccharides and disaccharides. The single units used in building all other carbohydrates are monosaccharides, for example glucose and fructose; two of these monosaccharides can chemically join in a reaction to form water and a disaccharide.
Polysaccharides are the complex carbohydrates. They are large molecules made up of smaller units, known as monomers. The monomers used in the formation of polysaccharides are monosaccharides, like glucose. Polysaccharides can also chemically combine to form new molecules; an example of…
