When ready, find out how much you understand about biomolecules and polymers by taking this chapter's multiple-choice quizzes and practice exam.
1. Aldose vs. Ketose Sugars
Aldose and ketose sugars are carbohydrate molecules distinctly different from one another. In this lesson, you'll learn about these sugars, discovering their unique characteristics and structure.
2. Monosaccharides: Definition, Structure & Examples
Carbohydrates are a very important part of our diet because they are one of our main sources of energy. The most basic unit of carbohydrates is monosaccharides, which is the main focus of our lesson.
3. Sugar Molecule: Structure & Formula
Sugar molecules are also known as carbohydrates. You have likely heard of simple and complex carbohydrates, but what is the difference? This lesson discusses the basic structure of sugars and how they combine to form complex carbohydrates.
4. Polysaccharide: Definition & Examples
Ever wonder what a polysaccharide is and why it's important? This lesson answers those questions, giving you everyday examples and relating their importance to your life.
5. What Are Amino Acids? - Definition & Structure
Your body cannot function without proteins, and in order to build all these important proteins, your body needs amino acids. In this lesson, learn what amino acids are and what they look like. Then test your new knowledge with a short quiz.
6. Proteins IV: Primary, Secondary, Tertiary and Quaternary Structure
How is progressing through higher order protein structures like crafting an essay? In this lesson, you'll explore everything from quaternary structures to denaturation as we show how the different structures are intertwined.
7. The Functions of Important Hormones
This lesson presents the function of each of the major hormones in the body and identifies the gland that secretes it. Take the short self-assessment quiz when you are through.
8. Classification of Vitamins: Water-soluble & Fat-soluble
Vitamins are classified based on their solubility. The fat-soluble vitamins are A, D, E and K. They can be stored in the body. The water-soluble vitamins are the B-complex vitamins and vitamin C. They are easily flushed out of the body.
9. Nucleic Acids: Function & Structure
In this lesson, we will explore what nucleic acids are, including the oozing bodily fluid they were first found in, what makes them unique from other types of biological molecules, and why DNA is called the 'blueprint of life.'
10. What Are Polymers? - Properties, Applications & Examples
Polymers are huge molecules that are encountered in nature as well as in our modern technology. This lesson introduces students to polymers, their properties, and some of the many ways polymers are found in the modern world.
11. Natural Polymers: Definition, Types & Examples
Discover the chemistry behind everyday substances like hair and starch by learning about polymers. We explore how polymers form, the chemistry of the reactions, and the three main types of natural polymers and their importance in everyday life.
12. Synthetic Polymers: Definition & Examples
Discover the chemistry behind some of the most popular and useful compounds ever made: synthetic polymers. Encounter some cool and common examples as you learn about the structures of these versatile compounds.
