About the lecture

In this lecture, we discuss the importance of understanding protein structure (Topic 3.13). We begin by highlighting that proteins serve as essential components in various cellular functions, such as enzyme catalysts, muscle contraction, transport, signalling, and biosynthesis of other biomolecules. Amino acids, the building blocks of proteins are then discussed. We describe their common structure, including the central carbon, amine, carboxylic acid, and the variable side chain. We briefly introduce different categories of amino acids based on their side chain properties, including hydrocarbons, amino acids with heteroatoms, aromatic amino acids, and charged amino acids. Finally we investigate the nomenclature and abbreviations commonly used for amino acids.
