Document Summary
Alpha carbon is the c beside the carboxy group. How a protein gets its structure dictates its function. Net charges are important because they dictate what other proteins they can bind to. Isolating one protein charges are very important in a cell. Creating a drug by binding something to the protein charge important. The protein is surrounding by a lot of water molecules which can exchange hydrogen with the amino acid constant dynamic movement going on within the solution with the amino acid. Nh2 can be nh3 +, coo- (carboxy) some side chains can carry a charge. Molecule possessing a highly polar covalent bond between a hydrogen and another atom dissolves in water. The hydrogen atom has given up its electron almost entirely to the companion atom, and so exists as an almost naked positively-charged hydrogen nucleus (a proton)
