A biomolecule or biological molecule is a loosely related expression for molecules and atoms that are existing in organisms, necessary to any typically organic process such as cell division, morphogenesis, or growth. Biomolecules involve huge macromolecules such as proteins, carbohydrates, lipids, and nucleic acids, as well as little molecules so as of prime metabolites, secondary metabolites, and general outcomes.
A compound is considered a CARBOHYDRATE if it is a sugar, or starch, glycogen and their derivatives or cellulose and its derivatives. Proteins are a polymeric natural product typically composed of hundreds of amino acid residues. A lipid is any class of fatty acids or it derivatives. They are insoluble in water. Nucleic acids facilitate the transfer of genetic information. They are composed of monomers of a nucleotide made of a five carbon sugar, a phosphate group and a nitrogenous base.
