11.1 Introduction: The Four Major Macromolecules Within all lifeforms on Earth, from the tiniest bacterium to the giant sperm whale, there are four major classes of organic macromolecules that are always found and are essential to life. These are the carbohydrates, lipids (or fats), proteins, and nucleic acids. All of the major macromolecule classes are […]

When one large molecule is split (lysis means splitting) into two molecules with the addition of water and energy, the reaction is called hydrolysis. In each of ...
Proteins are the primary building materials of the body. Your hair, skin, muscles, and organs are composed mostly of proteins. Proteins are strong yet flexible, and they have a complex 3-D structure. Amino acids are the basic building blocks of proteins. Amino acids have an NH2 (amine) group on one end, a H-O-C=O (carboxyl) group on the other end, making it acidic, and an R group which extends from the central carbon atom. The chemical makeup of this R group varies from one amino acid to another and gives each amino acid its unique properties. There are 20 amino acids that are important to humans, and all proteins are made from combinations of these subunits. Chains of amino acids are called peptides. In the poly-peptide chain shown below, can you see the individual amino acids that are strung together in a repeating N-C-C pattern? Between the terminal C of one amino acid and the N of the next one, energy from ATP is used to pull the O-H from the C, and the H from the N, forming H2O and joining them in a peptide bond, lengthening the chain. When we get to the genetics section of the course, we will study protein synthesis. That's the process by which DNA instructions are transcribed into RNA, which is then translated into the amino acids that are strung together to form long poly-peptide chains. These chains are then woven together like strands in a rope or like threads in a blanket to form various proteins. When food is consumed, the proteins are broken down into their constituent amino acids and rebuilt into the proteins of the body. However, excess amino acids are not stored for future use, and the body only starts to break down its own proteins during starvation, when the ordinary sources of fuel (fats and carbohydrates) are not available.
