Ch 2: Organic Molecules

About This Chapter

Watch video lessons, and learn about the different aspects of organic molecules. Use the quizzes that follow each lesson to gauge your comprehension of the materials.

Organic Molecules - Chapter Summary and Learning Objectives

This chapter will provide you an introduction to organic molecules. You'll study functional groups, monomers and polymers. Lessons will cover carbohydrates, disaccharides, lipids, steroids and proteins in-depth. You'll get to study the function of carbohydrates and see the job they actually do. You'll also get to look at lactose intolerance and why it occurs. Also learn about the structure and function of steroids and proteins. Some of the specific topics that will be covered in this chapter include:

  • The definition of glucose
  • What glucose, galactose, fructose and sucrose have in common
  • A comparison of saturated and unsaturated fatty acids
  • The definition of carbon rings
  • A look at amino groups

VideoObjective
Introduction to Organic Molecules I: Functional Groups Study organic compounds, such as proteins, fats, carbohydrates, hydroxyl, amine, ether and carboxylic acids.
Introduction to Organic Molecules II: Monomers and Polymers Take an in-depth look at monomers and polymers.
Structure and Function of Carbohydrates Explore carbohydrates, including related concepts like monosaccharide, disaccharide, polysaccharide, cellulose, glycogen, starch and glucose.
Lactose Intolerance and the Major Disaccharides Discover the details of lactose intolerance, along with a look at disaccharides, like glucose, galactose, fructose, sucrose and maltose.
Structure and Function of Lipids Examine lipids, including a look at fats, oil, triglycerides, glycerol, saturated fatty acids and unsaturated fatty acids.
Steroids: Structure and Function Learn more about steroids, and study concepts like cholesterol and carbon rings.
Proteins I: Structure and Function Find out more about proteins and related ideas such as amino acids, enzymes, side chain, amino group and carboxyl group.

7 Lessons in Chapter 2: Organic Molecules
Introduction to Organic Molecules I: Functional Groups

1. Introduction to Organic Molecules I: Functional Groups

If you've ever wondered what gives vinegar that sour flavor, you may not realize that you have contemplated functional groups. View this lesson for an introduction to organic chemistry, functional groups and how they are part of your daily life.

Introduction to Organic Molecules II: Monomers and Polymers

2. Introduction to Organic Molecules II: Monomers and Polymers

From everyday man-made items like milk jugs and styrofoam to natural proteins and plant materials, the world is full of polymers! Check out this lesson to learn how polymers are constructed on a molecular level.

Structure and Function of Carbohydrates

3. Structure and Function of Carbohydrates

Carbohydrates are found in many foods that we eat and may be found as sugars, starches, or fiber. Learn more about these three distinct types of carbohydrates, and how they are distinguished through their chemical structures in this lesson.

Lactose Intolerance and the Major Disaccharides: Definition, Structure & Examples

4. Lactose Intolerance and the Major Disaccharides: Definition, Structure & Examples

Disaccharides are a class of sugar created by the combination of two monosaccharides. The three major disaccharides in your diet are maltose, sucrose, and lactose. In this lesson, you will learn about these disaccharides and a common digestive system disorder called lactose intolerance.

Structure and Function of Lipids

5. Structure and Function of Lipids

Molecules called lipids have long hydrocarbon chains that determine the way they act. They can be fats, oils, or hormones, and even exist in our cell membranes. Learn more about the chemical structure and biological function of various lipids in this lesson.

Steroids: Structure & Function

6. Steroids: Structure & Function

Steroids are a type of lipid that contains four rings of carbon atoms. Steroids can act as hormones in the body. In this lesson, you will learn about the different structures and functions of steroids, including the important role of a steroid called cholesterol.

Proteins I: Structure and Function

7. Proteins I: Structure and Function

We need our proteins, not just as a major food group but for the many useful roles that they play in our bodies. In our introductory lesson to proteins, you'll learn about the many functions we rely on them to perform.
