Learning Experiences, Section 5: (Units 17 - 20) 8. Describe the following for each major macronutrient category (protein, carbohydrates, fats): PROTEIN: Role in energy production Protein main role in energy production is to repair, maintain and support growth of body tissues and muscles. Proteins are responsible for everything from our structure (contractile proteins, fibrous proteins) to our hormones (most of the non-steroid hormones), enzymes, immune chemicals (immunoglobulins and antibodies) and our transport proteins, dietary protein is critical. Role in Performance Adequate protein intake is essential for building and strengthening muscle tissue before, during and most importantly after the training session. Protein intake is most important after a training session when the rates of protein synthesis and glycogen re-synthesis are increased. Recommended types (for the general healthy public) Protein is an essential macronutrient of the human diet. It is found in a large variety of foods that we consume. Regardless of the source, the protein that we eat gets broken down into its individual amino acids. Different sources of protein provide varying levels of amino acids and therefore differ in protein quality. Animal proteins such as meat, poultry, eggs, fish, milk, and cheese rank the highest on protein quality measures, while plant proteins rank lower. And although it’s a common belief that plants don’t contain all the essential amino acids, this isn’t completely accurate. Many plant foods do contain all the essential amino acids, and each food has a unique proportion of them (same as how each food contains a unique proportion of the essential vitamins and minerals). However, lean, whole food options are often preferred to supplements due to their steadier absorption and more complete nutrient profile.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
