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.. Debalina. . Mukhopadhyay. . . Containing carbon, hydrogen, nitrogen, oxygen. .

Acids usually have H as the cation. . H. Cl. Acids are named depending on whether they are oxyacids (ternary acids) or non-oxyacids (binary acids). a pure, dry sample of a soluble salt from an insoluble oxide or carbonate, using a Bunsen burner to heat dilute acid and a water bath or electric heater to evaporate the solution..
