Ch 4: Organic Biochemistry

About This Chapter

Refresh your memory of organic biochemistry with this chapter. Complete short lessons during your spare time to review the structure and processes of proteins, enzymes, carbohydrates, and lipids.

Organic Biochemistry - Chapter Summary

Brush up on the basics of organic biochemistry with this chapter. Our instructors help you review the structures, properties, and functions of proteins, enzymes, and lipids. Explore the different types of amino acids and recall their individual qualities. After you study these lessons, you should be able to:

  • Differentiate between lipids, carbohydrates, nucleic acids, and proteins
  • Establish the function and structure of carbohydrates, lipids, and proteins
  • Outline peptide bonds, amino acids, and polymerization in proteins
  • Evaluate the characteristics and structure of amino acids
  • Figure out the primary, secondary, tertiary, and quaternary structure of proteins
  • Inspect how enzymes function

Our site makes studying this information easier than ever because accommodate your schedule. All of our materials are available online with around-the-clock access - you'll never have to make an appointment to study. Make the most out of whatever time you have available with brief lessons lasting about eight minutes apiece. Since the organic biochemistry information you need to know is available in one place, you won't have to worry about carrying your study materials around. All you need is an Internet-ready device, a Wi-Fi signal, and you can transform practically any location into a mobile study station.

Major Elements in Biological Molecules: Proteins, Nucleic Acids, Carbohydrates & Lipids

1. Major Elements in Biological Molecules: Proteins, Nucleic Acids, Carbohydrates & Lipids

Bacterial cells have complex macromolecules built from simple molecules. In this lesson, we will look at the major elements in the building blocks of proteins, nucleic acids, carbohydrates, and lipids.

Introduction to Organic Molecules I: Functional Groups

2. 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

3. 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

4. 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.

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.

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.

Function of Enzymes: Substrate, Active Site & Activation Energy

10. Function of Enzymes: Substrate, Active Site & Activation Energy

In this lesson, we'll learn how enzymes function to lower the activation energy of a chemical reaction. Enzymes bind to their substrates to perform all kinds of important and essential cellular processes, as well as processes that help you enjoy a slice of pizza!
