Ch 5: Campbell Biology Chapter 5: The Structure and Function of Large Biological Molecules

About This Chapter

The Structure and Function of Large Biological Molecules chapter of this Campbell Biology Companion Course helps students learn the essential lessons associated with the function and structure of large biological molecules. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Structure and Function of Large Biological Molecules textbook chapter.

How It Works:

  • Identify the lessons in the Campbell Biology Structure and Function of Large Biological Molecules chapter with which you need help.
  • Find the corresponding video lessons with this companion course chapter.
  • Watch fun videos that cover the large biological molecules topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn:

  • Properties and applications of polymers
  • The structures of proteins, carbohydrates and lipids
  • Functions of carbohydrates, lipids and proteins
  • The process of hydrolysis
  • Traits of the 20 amino acids
  • Higher order protein structures
  • The structure of nucleic acids
  • Benefits of genomics

11 Lessons in Chapter 5: Campbell Biology Chapter 5: The Structure and Function of Large Biological Molecules
What Are Polymers? - Properties, Applications & Examples

1. 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.

Structure and Function of Carbohydrates

2. 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.

Chemical Digestion of Carbohydrates: Definition & Process

3. Chemical Digestion of Carbohydrates: Definition & Process

Carbohydrates are an important energy source, but must be broken down to be absorbed out of the digestive tract. In this lesson, you will learn how disaccharides and polysaccharides are broken down to monosaccharides through a process called hydrolysis.

Structure and Function of Lipids

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.

Lipids: Types & Nutritional Role

5. Lipids: Types & Nutritional Role

There are different types of lipids, and each one plays a role in your health. Learn how triglycerides, phospholipids and steroids differ in their chemical structure and the jobs they do within your body.

Proteins I: Structure and Function

6. 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.

Proteins II: Amino Acids, Polymerization and Peptide Bonds

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.

Proteins III: Structure and Characteristics of the 20 Amino Acids

8. 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.

Proteins IV: Primary, Secondary, Tertiary and Quaternary Structure

9. 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.

DNA: Chemical Structure of Nucleic Acids & Phosphodiester Bonds

10. DNA: Chemical Structure of Nucleic Acids & Phosphodiester Bonds

In this lesson, you'll discover what nucleotides look like and how they come together to form polynucleotides. We'll also explore nucleic acids and focus on DNA in particular.

Genomic DNA Analysis

11. Genomic DNA Analysis

Your genes are what make you who you are, but they also make you a human. Studying genes and genomes allows scientists to better understand not only our own species, but how we are related to other species in the world as well.
