Types of Compounds. Ionic compounds are compounds composed of ions, charged particles that form when an atom (or group of atoms, in the case of polyatomic ions) gains or loses electrons. 1  A cation is a positively charged ion. 2  An anion is a negatively charged ion.
Porins are members of an extended family of transmembrane proteins found in the outer membrane of gram negative bacteria such as E. coli, or in the outer membranes of mitochondria in eukaryotes. The general porins provide a simple diffusion pathway across the membrane for molecules less than 1 kDa with little substrate selectivity.
Best Answer: The proteins that make up the virus particle are called STRUCTURAL PROTEINS. The protein coat of the virus is called the CAPSID and is made up of numerous CAPSOMERES.The combination of the viral nucleic acid and the protective protein is called the NUCLEOCAPSID. Some viruses are encased in a protective membrane called the ENVELOPE.The whole virus particle (all the parts) is called the VIRION.he combination of the viral nucleic acid and the protective protein is called the NUCLEOCAPSID.
