PPT-Peptides and Proteins 20 amino acids are commonly found in protein. These 20 amino acids

Peptide bond formation αcarboxyl group of one amino acid with side chain R1 forms a covalent peptide bond with αamino group of another amino acid with the side chain R2 by removal of a molecule of water The result is Dipeptide ie Two amino acids linked by one peptide bond By the same way the dipeptide can then forms a second peptide bond with a third amino acid with side chain R3 to give . 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.. - . Basic dairy chemistry & Functionality of Milks. 2009. 06. 17. Geun-Bae. . Kim.

Each amino acid (aa) shares a common structure; i.e. an amine (NH. 2. ) group, an acid group (COOH), and a central carbon atom bonded to hydrogen and to a side chain (R).. The side chains qualify aas as acidic, basic, neutral, aromatic, and sulphur-containing amino acids.. Amino Acids are the building units of proteins..
