Watch Anatomy And Physiology Chapter 4

In this section we look at the molecular structure of adenosine triphosphate or ATP. We discuss how it is able to store and release energy, and how it is able to be re-used by cells in the body.

In this section we cover the structure of the two main types of nucleic acids, DNA or deoxyribonucleic acid and RNA or ribonucleic acid.

In this section we look at the four different levels of protein shape; primary, secondary, tertiary or the third level, and quaternary or the fourth level. We discuss the formations formed by proteins in each of the levels, and why the shape of a protein is important. We also cover how proteins can have their shape altered by denaturation.

In this section we look at how amino acids link together to form proteins. We cover the molecular structure of amino acids and list the essential and non essential amino acids. We also discuss how the different amino acids are classified and how they form peptide bonds and long polypeptide chains. We also look at some of the different ways protein structures serve the body.

In this section we look at the different types of fatty acids; saturated fatty acids, monounsaturated fatty acids, polyunsaturated fatty acids and trans fatty acids. We discuss the molecular structure of each of these as well as some foods that are high in each of them. We also cover omega fatty acids and how the omega carbon location defines the type of omega fatty acid.

In this section we go over the molecular structure of the major types of lipids or fats; triglycerides, phospholipids, steroids, and prostaglandins.

In this section we look at the 3 different types of carbohydrates, monosaccharides, disaccharides, and polysaccharides. We discuss the structure of each of these types of molecules and how smaller carbohydrates join to form larger carbohydrates.

In this section we take a general look at the major groups of organic molecules, carbohydrates, lipids or fats, proteins and nucleic acids. We also discuss what characteristics make a molecule to be classified as an organic molecule.
