About This Chapter
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
|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.|
1. Introduction to Organic Molecules I: Functional Groups
Organic molecules contain carbon and other atoms often found together and behaving similarly are called functional groups. Learn about carbon and atoms in functional groups in this introduction to organic molecules.
2. Introduction to Organic Molecules II: Monomers and Polymers
Polymers can be defined as long-chain molecules composed of small monomers. Dig deeper into the relationship between monomers and polymers in this introduction to organic molecules.
3. Structure and Function of Carbohydrates
Carbohydrates are organic compounds composed of carbon, hydrogen, and oxygen, and contain various functional groups. Learn about the structure and function of different carbohydrates like sugars, fiber, and starches, and the function of carbs in humans.
4. Lactose Intolerance and the Major Disaccharides: Definition, Structure & Examples
When sugar molecules, or saccharides, are linked together, they form disaccharides, one of which is the root of the condition called lactose intolerance. Explore the structures and examples of the major dietary monosaccharides and disaccharides, and understand why lactose intolerance occurs.
5. Structure and Function of Lipids
Lipids, commonly known as fats and steroids, are polar molecules that are essential to life. Explore the different structures and types of lipids--such as fats, oils and hormones--and how structure determines the type and function.
6. Steroids: Structure & Function
Regardless of the type, all steroids have similar fundamental chemical structures and are considered lipids. Discover more about steroids, including their structure, function, and how steroids derive from cholesterol.
7. Proteins I: Structure and Function
Proteins can be defined as molecules composed of amino acids and peptide bonds. Learn about the structure and function of proteins using keratin as an example.
