Homework Answers
1. L glycine and D glycine are sterioisomers. They are the only aminoacid with no enantiomer.
2. L-tryptophan and D-tryptophan are enantiomers. The orientation of these molecules is only different.
3. Val-ile-phe is a peptide formed of three aminoacids valine, isoleucine, phenylalanine. Peptides are compounds formed by the interaction of two or more aminoacids by peptide bond.
4.Asparagine is a polar aminoacid with a polar group in its side chain.
5. Methionine is a nonpolar amino acid. It's side chain is not polar. It is also a neutral amino acid.
6.isoleucine and leucine isomers of each other.

The chemical structures of the 20 standard amino acids at pH 7, along with their 3 and 1 letter codes, are givern in alphabetical order below. While the oxygen and nitrogen atoms of the peptide bonds may serve as a donor atom to complex a metal ion, very often the ligands for the metal come from the amino acid side chains. Takea few moments to examine the chemical structures of the different side chains. Circle the side chains that you...

1. Partial hydrolysis of lysozyme yielded an octapeptide that was later identified as the N-terminal segment of the protein. From the following information, determine the sequence of this octapeptide. a. The following amino acids were identified after complete hydrolysis of the octapeptide: Arginine (Arg) Glycine (Gly) Phenylalanine (Phe) Cysteine (Cys) Leucine (Leu) Valine (Val) Glutamic Acid (Glu) Lysine (Lys) b. Treatment of the octapeptide with dinitroflurobenzene (Sanger reagent) followed by complete hydrolysis gave lysine (Lys) labeled with two dinitrophenyl (DNP) groups. c. Treatment of the octapeptide with trypsin gave lysine...
