About This Chapter
Macromolecules in Nutrition - Chapter Summary
While studying these lessons, you will heighten your understanding of macromolecules in nutrition. This chapter can help you understand how carbohydrates spare proteins, which helps with fat metabolism. Another topic covered is the importance of vitamins and where they're found. After reviewing the lessons, you should be ready to:
- Explain why carbohydrates are important
- Discuss the nutritional role and chemical structure of lipids
- Recall potential health problems associated with lipids
- Describe how proteins regulate body processes
- List health effects associated with proteins
- Explain how minerals from food function in the body
- Discuss the amount of water our body needs on a daily basis
- Recall the consequences of an imbalanced diet
The lessons in this chapter contain vocabulary words highlighted in bold for quick reference. If you get stuck on a topic, you can submit questions to instructors by using the Help feature. Video timelines let you navigate to specific topics based on what you need to study. Each lesson includes a full written transcript that you can print and use as another study tool.
1. The Importance of Carbohydrates: Functions & Impact of Deficiency
The main function of carbohydrates is to provide the body and brain with energy. An adequate intake of carbs also spares proteins and helps with fat metabolism. Learn about the roles carbohydrates play and what happens when you don't get enough of them.
2. Lipids: Types & Nutritional Role
There are different types of lipids, and each one plays a role in your health. Learn how triglycerides, phospholipids and steroids differ in their chemical structure and the jobs they do within your body.
3. Health Effects Associated with Lipids
Lipids, or fats, are important nutrients that your body needs for proper functioning. But eating too many fats, especially the unhealthy fats, such as saturated fats and trans fats can lead to heart disease, cancer and obesity.
4. Primary Functions of Protein in the Body
Protein is a vital molecule that carries out many functions in your body. Learn how proteins provide structure, regulate body processes, transport materials throughout your body, help your immune system and act as a source of energy.
5. Health Effects Associated with Proteins
If a diet is deficient in protein, it can lead to a type of protein-energy malnutrition (PEM), such as kwashiorkor or marasmus. If a diet is too high in protein, it can lead to dehydration or increase the risk of heart disease or cancer. Learn about all of this and more in this lesson.
6. Minerals in Our Food: Functions in the Body & Food Sources
Minerals are important substances that help your body's form and function on many different levels. This lesson will go over some important ones, what they do, and where they are found in our diets.
7. Vitamins We Need: Their Importance & Sources
There are a lot of different vitamins, and they come from many different places! This lesson will teach you about what they are, how many different kinds you need, what they do, and where you can obtain them naturally.
8. Water's Role as a Nutrient: Importance & Dietary Need
Water is an important thing for the entire world and the world inside your body. This lesson will point out why it's important for you and how much you need on a daily basis.
9. Imbalanced Diet: Effects & Causes
This lesson discusses an imbalanced diet. You'll learn the nutrients that may be in excess or in deficiency, what the causes of an imbalanced diet may be, and the potential consequences of an imbalanced diet.
