Title: Week 6 - Unit 2_4 Proteins
Course: Biochemistry

Introduction

Proteins are of the primary importance in cellular life as they are found in all aspects of cell structure and function. Some are enzymes, hormones, storage proteins, contractile proteins, transport proteins, structural proteins, protective proteins and toxins. A protein is composed of one or more long chains composed of amino acids. The individual amino acid subunits are joined by amide linkages called peptide bonds.

Expectation

In this lesson, you'll learn about the primary structure, function, and sources of protein molecules while exploring some real-world examples and illustrations.

Course outline

1. Amino Acids
2. Peptide bonds
3. Proteins

Learning outcomes

At the end of this unit, you should be able to:

1. Recognize the chemical structure of each of the 20 standard amino acids
2. Describe the two basic building blocks of protein structure (α-helix and β-sheet)
3. Describe levels of protein structure
4. Describe the forces and interactions that promote protein folding
5. Define the process of protein denaturation
