PPT-PROPERTIES OF AMINO ACIDS

A PHYSICAL PROPERTIES Optical properties All amino acids except glycine possess optical isomers due to the presence of asymmentric carbon atom Some amino acids have a second assymmentric carbon eg isoleucine threonine. What are amino acids?. Amino acids are the building blocks of proteins.. In the body, they exist as zwitterions.. Zwitterions can behave as both an acid or a base.. Today we will:. Study . the acid-base properties of amino acids, . CHAPTER 3, Part 1 . Amino Acids and Peptides . To know the structure and naming of all 20 protein amino acids. To know the structure and properties of peptides and the particularly the structure of the peptide bond.. Subunits (building blocks) of peptides and proteins. Neurotransmitters. Metabolic intermediates. glutamate. γ. -. aminobutyric. acid. (GABA). Proteins are synthesized from 20 ‘standard’ . α. -amino acids. Their names have 3- and 1-letter abbreviations.. Debalina. .
