Introduction to Peroxisomes: Peroxisomes are small membrane-bound, self-replicating organelle found in nearly all eukaryotic cells. They contain oxidative enzymes, such as D-amino acid oxidase, ureate oxidase, and catalase. They are a [...]
The below mentioned article provides a short note on the Disorders of Plasma Membranes. Mutations affecting the protein constituents of membranes can cause many diseases. Proteins in membranes are classified as receptors, transporters, ion channels, enzymes, and structural components. All these classes are often glycosylated, so that mutations affecting this process may change their function. Almost 30 genetic disorders have [...]
In this article we will discuss about the Intercellular Contact and Communication of Plasma Membranes. Cells have developed specialized regions on their membranes for intercellular communication. Gap junctions mediate and regulate the passage of ions and small molecules through a narrow hydrophilic pore connecting the cytoplasm's of adjacent cells. These pores are composed of subunits called "connexions". Connexions consist of [...]
