Membrane Biochemistry centers around the all biochemical and bio physiological parts of layer structure and work and furthermore their constituent protein and lipid segments.
Biological membranes fall into two general categories, extracellular (e.g., glomerular basement) and cellular (e.g., plasma and intracytoplasmic). We have elected to confine this review to cellular membranes. Because of space limitations. this report will not attempt to cover the entire area of membrane biochemistry but will present a critical review in depth of several selected subjects. The review will be divided into two main sections: (a) the biochemistry of cellular membranes; and (b) artificial membrane system
This group includes nuclear membrane, mitochondrial membranes, cytoplasmic or plasma membrane, and the membrane components of the endoplasmic reticulum and other intracellular organelles. All members of the group contain large amounts of phospholipid and protein, and they exhibit a characteristic trilamlnar "unit membrane" structure when fixed sections are studied by electron microscopy. Earlier biochemical studies were handicapped by difficulty in obtaining purified preparations, and the question of contamination by nonmembrane components is still a recurring problem. In recent years, however, techniques have been developed for isolation of large amounts of membrane material from bacteria and from cells of higher organisms. Bacteria
