|Physical Biochemistry is the study of biological system with the concepts of physics and physical chemistry for the study of biological systems. Physical Biochemistry deals with the structure of biological macromolecules at various levels and how their chemical structure impacts physical properties of a substance and the biological process. Physical biochemistry uses different techniques to analyse the rate of a biochemical reaction, molecules interaction, calculation of structures and functional properties of the biological system. A journal is a periodical publication intended to further progress of science, usually by reporting new research. Most journals are highly specialized, although some of the oldest journals publish articles, reviews, editorials, short communications, letters, and scientific papers across a wide range of scientific fields. Journals contain articles that peer reviewed, in an attempt to ensure that articles meet the journal's standards of quality, and scientific validity. Each such journal article becomes part of the permanent scientific record.
