The functions of proteins
A protein is a polymer constructed from a set of 20 kinds of monomers called amino acids. It functions almost every organisms on earth. It structure our hair, muscles, and circulate our blood and defend our body from harmful microorganisms.
Amino Acids
Amino acid monomers consists of a central carbon atom bonded to four partners. One partner is hydrogen atom and two other atom s are carboxyl group. The side group is called as the 'R-group' is responsible for the particular chemical properties of each amino acid. Other side group is hydroxyl so it attracts water.
Building a Protein
Cell create proteins by linking amino acids together into a chain called a polypeptide. Like creating polumer chain, each link is created by dehydration reaction. There are 20 kinds of monomers that forms protein channel.
