summary of biological molecules
The biological molecules or Biomolecules are involved in metabolic activities of living bodies such as plants and animals. They are usually polymers or macromolecules which are composed by the polymerisation of monomer units.iological molecules play an important role in the survival of living cells. For example, nucleic acids are involved in the transfer of genetic information and synthesis of proteins. Carbohydrates provide energy to living cells for their activities.
1. The larger biological molecules are made from smaller molecules. Polysaccharides are made from monosaccharides, proteins from amino acids, nucleic acids from nucleotides, lipids from fatty acids and glycerol. 2.Polysaccharides, proteins and nucleic acids are formed from repeating identical or similar subunits.called monomers, and are therefore polymers.ondensation involves removal of water. The reverse process, adding water, is called hydrolysis and is used to break the large molecules back down into smaller molecules. 4. The linkages that join monosaccharides are called glycosidic bonds.
