The structure and function of Proteins This essay clearly divides into two sections: structure, and function. Hence I will begin by talking about the structure of Proteins and will go on to talk about their functions. The building blocks of proteins are "amino acids", which differ to other molecules due to their nitrogen content. The basic amino acid looks like this, with a line of N-C-C. The N has two H atoms bonded to it, while the end C atom has a double bond to an oxygen atom and has a hydroxyl group bonded to it. The middle carbon atom bonds with a H atom, and has a "variable side group" attached onto it. Amino acids are very soluble, principally for the reason that the Oxygen and Nitrogen in them is very electronegative, meaning that the amino acids are readily carried around in aqueous state. Amino acids are "amphoteric" meaning that in different circumstances...
