Search Results Featured snippet from the web Physical biochemistry is a branch of biochemistry that deals with the theory, techniques and methodology used to study the physical chemistry of biomolecules. It also deals with the mathematical approaches for the analysis of biochemical reaction and the modelling of biological systems. Physical biochemistry involves the study of the structure of macromolecules in terms of the number of atoms they have, the arrangement of atoms, and the symmetry of the molecules. Monomers (building blocks) are the foundation of the structure of macromolecules. Monomers bond with other compounds to form macromolecules (these can also be called polymers). Macromolecule structures are very complex and contain four substructures
