About This Chapter
Organic Chemistry and Biochemistry - Chapter Overview
This chapter is designed to provide you with an overview of the properties, structure and chemical reactions of organic compounds and materials, as well as the chemical processes associated with living organisms. It begins with a discussion of molecules, including alkanes, alkenes, aromatic hydrocarbons and isomers. You'll also learn about the different kinds of functional groups, or clusters of atoms, found in organic molecules.
Additional topics include the structure and function of carbohydrates and lipids, and the instructor will also discuss the ten simplest types of hydrocarbons humans rely upon for energy. Through a 4-part protein sequence, you'll also learn about the following:
- The structure and function of proteins
- Amino acids, peptide bonds and polymerization
- The characteristics and structure found in the 20 amino acids
- How proteins are organized, including primary, secondary, tertiary and quaternary structures
Our video lessons on organic chemistry and biochemistry are taught by experienced instructors. Additional formats include lesson transcripts, where key terms are linked to a text-based lesson and the opportunity to find out more information. When you finish the chapter, you can use the online self-assessment quizzes to test your own knowledge of this complex subject. Other features include video tags that allow you to revisit major points of the presentation without having to watch the entire video again.
1. Organic Molecules: Alkanes, Alkenes, Aromatic Hydrocarbons and Isomers
Learn more about carbon and hydrogen and see how these atoms come together to form distinct molecules. Also, study the difference between saturated and unsaturated molecules.
2. Functional Groups in Organic Molecules
Learn what an organic compound is and how their functional groups affect them. Identify the different types of functional groups including alcohols, alkyl halides, ketones, aldehydes, ethers, carboxylic acids and esters.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
8. 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.
