Even though a protein can be very complex, it is basically a long chain of amino acid subunits all twisted around like a knot. As proteins are being built, they begin as a straight chain of amino acids. This chain structure is called the primary structure. After the primary structure comes the secondary structure.
The original chain begins to twist. It’s as if you take a piece of string and twist one end. It slowly begins to curl up. Let’s move on to the tertiary structure of proteins. By now you’re probably getting the idea that proteins do a lot of folding and twisting. The third step in the creation of a protein is the tertiary structur.
We can finally cover the quaternary structure of proteins. This is the fourth phase in the creation of a protein. In the quaternary structure, several amino acid chains fromthe tertiary structures fold together in a blob. Blob” is the term we use on this site. They wind, entwined, in and out of each other. 1997-2017 Andrew Rader Are digestive enzymes necessary after gallbladder removal, All rights reserved.

Every combination of atoms is a molecule. A compound is a molecule made of atoms from different elements. All compounds are molecules, but not all molecules are compounds. Ionic bonds occur when electrons are donated from one atom to another. You may also learn about a third type of bond. Metallic bonds occur between metal atoms. We’re going to focus on ionic and covalent bonds.
