About This Chapter
Who's it for?
Anyone who needs help learning or mastering college biology material will benefit from taking this course. There is no faster or easier way to learn college biology. Among those who would benefit are:
- Students who have fallen behind in understanding the structure and function of organic molecules
- Students who struggle with learning disabilities or learning differences, including autism and ADHD
- Students who prefer multiple ways of learning science (visual or auditory)
- Students who have missed class time and need to catch up
- Students who need an efficient way to learn about organic chemistry
- Students who struggle to understand their teachers
- Students who attend schools without extra science learning resources
How it works:
- Find videos in our course that cover what you need to learn or review.
- Press play and watch the video lesson.
- Refer to the video transcripts to reinforce your learning.
- Test your understanding of each lesson with short quizzes.
- Verify you're ready by completing the Introduction to Organic Chemistry chapter exam.
Why it works:
- Study Efficiently: Skip what you know, review what you don't.
- Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.
- Be Ready on Test Day: Use the Introduction to Organic Chemistry chapter exam to be prepared.
- Get Extra Support: Ask our subject-matter experts any organic chemistry question. They're here to help!

Students will review:
In this chapter, you'll learn the answers to questions including:
- What are the functional groups of organic molecules?
- In what way are monomers and polymers different?
- How are carbohydrates organized and what is their purpose?
- What are lipids and how are they structured?
- How are proteins structured and what is their function?
- What are amino acids and and peptide bonds?
- How does polymerization work?
- What are the characteristics of the 20 amino acids?
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.
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.
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.
4. 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.
5. 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.
6. Proteins II: Amino Acids, Polymerization and Peptide Bonds
In this lesson, we'll take a deeper look at amino acids. You'll learn what makes a peptide, and what separates a protein from other kinds of amino acid bonds.
7. Proteins III: Structure and Characteristics of the 20 Amino Acids
How do amino acids form the intricate polypeptide chains found in proteins? It's a matter of chemistry. Join glycine, a special amino acid, as she sizes up the other amino acids.
8. 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.
9. Amide: Definition, Structure & Formation
Amides are a type of functional group that can't be missed given the presence of a nitrogen atom in these compounds. Learn more about amides, their structure, and formation. Test your knowledge by taking a quiz at the end of this lesson.
10. Copolymer: Structure & Properties
A copolymer is a type of polymer that is used in a wide variety of products, such as plastics and car tires. Learn more about copolymers and understand their different types, structures, and properties in this lesson.
11. Globular Proteins: Definition, Structure & Examples
Explore what makes globular proteins different from other groups of proteins. Learn about the definition and structure of globular proteins as well as some examples and their functions.
12. Hydrogen Bonds: Definition, Types & Formation
Hydrogen bonds are electromagnetic attractions between the positive and negative poles of atoms. These bonds are weak and easily broken, but account for many of the important properties of things like water and DNA.
13. Polypeptide: Definition, Formation & Structure
Polypeptides are chains of amino acids and essential portions of proteins in cells. In this video, learn how polypeptides are formed and what's unique to their structure.
