Amino Acids
Amino acids are basic building blocks of proteins. In this chapter structure, types, optical properties, absolute configuration of amino acids are covered. The chapter describes the difference between standard and non-standard amino acids.
Structure and Types of Amino acids
Amino acids are molecules used to build proteins. All amino acids have a central carbon atom surrounded by a hydrogen atom, a carboxyl group (COOH), an amino group (NH2), and an R-group. It is the R-group or side chain that differs between the 20 amino acids.
Following videos lectures cover it in depth.

Optical Properties of Amino Acids
Optical properties of amino acids are attributed by different groups attached to alpha carbon atom. The lectures describe it in details.
Absolute Configuration of Amino Acids
The absolute configuration of amino acids depend upon the chemical properties of the groups attached the alpha carbon. The absolute configuration of amino acid plays vital role in the structure of proteins and enzymes. The below videos details it in depth.
Standard Amino Acids
What are standard amino acids?
Non-standard Amino Acids
How does non-standard amino-acids differ from standard amino acids?
Titration of Amino acids
Titration of amino acids, calculation of pI (Isoelectric point) and pH of amino acids is explained in the following videos.
