Document Summary

All the proteins in the body are made from the 20 amino acids coded for by our dna: proteins run all the biochemical processes in the body. The unique sequence of amino acids in each protein (the primary structure) predicts its conformation. The properties of side chains on each amino acid dictates the associations between them leading to the conformation of the protein. Dna has blueprints for how to make proteins. Primary structure: the list of amino acids in the exact order that they need to occur as dictated by the dna. The order the(cid:455)"re i(cid:374), i(cid:374) the pri(cid:373)ar(cid:455) stru(cid:272)ture is goi(cid:374)g to di(cid:272)tate ho(cid:449) the(cid:455) are goi(cid:374)g to fold in 2-d in their secondary structural elements (elements within) Curly rings are known as alpha helices secondary structure. Quaternary structure: 4 different proteins that come together and interact in a specific way: not all proteins have it. All the 20 amino acids have a common structure.
