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.
Complement Proteins. Complement proteins are two or more incomplete protein sources that together form a complete protein. If a protein is low in a certain amino acid, like lysine, a complement protein is one that provides the missing protein, in this case lysine.Together, these two proteins provide you with all of the essential amino acids that your body needs to function properly.omplement Proteins.
