Ch 5: AP Biology - Organic Chemistry: Homework Help

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 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.

7. 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.

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. Hexane: Structure, Formula & Properties

Did you know that hexane plays a role in the production of different vegetable oils stored in our cupboards? Explore this lesson to learn more about the organic molecule hexane, its structure, formula, and properties.

10. Quaternary Structure of Protein: Definition & Overview

Proteins have four levels of structure: primary, secondary, tertiary, and quaternary. The first three involve only one molecule. However, quaternary structure describes how proteins interact to form complex molecular structures.

11. Secondary Structure of Protein: Definition & Overview

There are four levels to protein structure. Primary is encoded in DNA. Secondary involves interactions within the protein. Tertiary and quaternary involve chemical interactions within and without the protein. This lesson describes secondary structure.

12. Specific Rotation: Formula & Calculation

In this lesson, we'll talk about specific rotation. We'll go over the types of molecules that specific rotation is useful for and use the formula to complete a practice problem.

13. What is Polyethylene? - Properties & Uses

When you grabbed that plastic grocery bag, I bet you didn't know it contained the compound polyethylene. Let's learn more about polyethylene, including its properties and uses.

14. RuBisCO Protein: Definition, Function & Structure

Without photosynthesis, life as we know it would not exist. This lesson will examine RuBisCO, an enzyme that is involved in photosynthesis, looking at how it works and why it is considered one of the most important enzymes on the planet.
