CHM 230 F'19 Amino acids/peptides Worksheet 1. Draw the structure, at pH 7, of a tetrapeptide that is composed of four different amino acid residues, each from a different category (classification). Draw an arrow to every peptide bond in this peptide. Identify by name the C-terminal residue and the N-terminal residue. Give the abbreviation of this tetrapeptide using three-letter codes. 2. Identify the amino acid residue whose R groun is drawn below in the "clothes line" format

1. draw the structure of amino acid lysine at pH=1.00 and pH=12.00. 2. find the overall charge of the amino acid at each pH. 3. what will be the overall charge on the peptide alanine-glycine-lysine-serine-aspartate at pH=1.00 and pH=12.00?
Submit the structures, 3-letter codes, and 1-letter code of all of the amino acids, drawn out please with pen! Thank you.
1 - Draw the chemical structure of ATP. Describe what is the same, and what is different from the 'A' in an RNA strand. Besides being used to make RNA, what other biological importance does ATP have? 2 - What is the central paradigm of Molecular Biology? What are the molecular machineries that facilitate each step? 3 - Draw the chemical structure of the amino acids glycine, alanine, valine, leucine, and isoleucine. Give a reason why an organism would need...
Which three statements about amino acids are true? Use this chart of amino acid structures for reference. Lysine has one stereocenter (chiral center). Methionine is a thiol. The Leu side chain does not form hydrogen bonds with other amino acids. The form of glycine used by the human body is D-glycine. Ser and Thr are polar amino acids. Proline has an overall charge at physiological pH (7.4).
Choose three amino acids, no more than one of each of the following types: a. polar side group b. non-polar side group c. acidic side group d. basic side group Draw an unambiguous structure for each of the amino acids you chose, in the full propionate form (at pH=0). That is, all oxygen/sulfur sites should be neutral, and appropriate amino sites should have a+1 charge. For full credit, show all stereochemistry properly. a. b. c. CIRCLE the side groups for...
