Cellular membranes are known to participate in several biological functions
in addition to providing cellular integrity. Interestingly, in a small nanometric
thickness, they offer a range of polarity, viscosity, and heterogeneity in addition to their
lateral organizational diversity, which makes biological membranes a unique medium
to carry out several cellular reactions. In this chapter, we have discussed the membrane
architecture, physical properties, and its contribution to several biological functions.
Keywords: Acylation of proteins, Biomembrane architecture, Electron transfer, Glycosylation, Lipid biosynthesis and sorting, Membrane heterogeneity, Membranes, Oxidative phosphorylation, Protein sorting, Signal transduction.
