A protein is a long chain molecule made up of amino acids joined together by peptide bonds. Peptides are compounds which form by linking one or more amino acids with a covalent bond, (one of the strongest type of chemical bond). The amino acids form the building blocks of proteins. It is from these amino acid groupings that proteins are made. There are a total of 20 different kinds of amino acids that form proteins and different amino acids determine the shape of the proteins formed. Amino acids are very common, in fact, they make up 75% of the human body. Here are some facts about proteins. Our body can produce 14 of the 20 necessary proteins. But the remaining ones we have to get from the foods we eat.

Another kind of protein, called enzymes, generate energy in our body. So the study of proteins has to start with the subject of protein synthesis. This involves the process where individual cells construct proteins, and both deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are involved in this process. Bright Hub has a wide variety of articles dealing with proteins and protein synthesis. Learn more about the process here!
