Human metabolism refers to life-sustaining chemical processes that occur in our cells and are essential for our bodies to grow, maintain their structures, and respond to their environments. This nutrition course will teach you all about metabolism and how you obtain energy from three classes of fuel molecules. By the end of the course, you will understand the function and importance of carbohydrates, lipids, and proteins for life sustenance.

This course will first introduce you to metabolism and its anabolic and catabolic processes. You will study oxidation and reduction as well as their two common cofactors and their functions. The course will then discuss monosaccharide metabolism as well as the processes of glycogenesis and glycogenolysis. You will study glycolysis and the transition reaction, the citric acid cycle, and the electron transport chain. You will also learn about anaerobic respiration and the Cori cycle.

You will then study the five lipid metabolic pathways including lipolysis and ketogenesis. The course will discuss the two primary lipolysis enzymes, the two metabolic fates of glycerol, and the two enzymes involved in oxidation process of fatty acids. You will look into the three ketone bodies, fatty acid synthesis, ketone body synthesis, and cholesterol synthesis. Finally, you will learn about the different protein metabolism pathways, transamination, deamination, gluconeogenesis, and protein degradation.

Metabolism is the process of converting everything that you eat and drink into energy. This is absolutely essential to life itself. With this course, you can gain a comprehensive understanding of this vital process. this is not only interesting knowledge, it's also highly useful for nutritionists, biologists, and anyone who wants to understand more about their bodies to be a little bit healthier. So, check out the course today and kick off your next learning journey.
