A representation of the 3D structure of myoglobin, showing alpha helices, represented by ribbons. This protein was the first to have its structure solved by X-ray crystallography by Max Perutz and Sir John Cowdery Kendrew in 1958, for which they received a Nobel Prize in Chemistry.

A biomolecule is any molecule that is produced by a living organism. This includes large macromolecules such as proteins, polysaccharides, lipids, and nucleic acids, as well as many smaller molecule A more general name for this class of molecules is biogenic substances.

Types of biomolecules[change | change source]

A diverse range of biomolecules exist, including:

Biomonomers Bio-oligomers Biopolymers Covalent bond name between monomers
Amino acids Oligopeptides Polypeptides, proteins (hemoglobin...) Peptide bond
Monosaccharides Oligosaccharides Polysaccharides (cellulose...) Glycosidic bond
Nucleotides Oligonucleotides Polynucleotides, nucleic acids (DNA, RNA) Phosphodiester bond
