1- Hydrogen bonding between the two antiparallel strands of protein fragments described below; also show structural and spatial details ( including the correct stereochemistry for an L-amino acid) of the specific “R” groups corresponding to the amino acids specified:
-NH-Gly-Phe-Ser-Ala-CO- & -CO-Tyr-Gly-Arg-Met-NH-
2- Provide a mechanistic explanation detailing how the catalytic triad of serine, histidine and aspartic acid, found in the active site site of the enzyme chymotrypsin, facilitates peptide hydrolysis. Clarify the role played by each of these amino acids in the overall process.
3- Provide a schematic synthetic strategy for the synthesis of the following tripeptide via Merrifield’s solid-phase synthesis: Val-Phe-Ile

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...

Question Completion Status: Question 10: The genetic code consists of 64 triplets of nucleotides (called codons). Each codon (with the exception of the 3 stop codons) encodes for one of the 20 amino acids used in the synthesis of proteins. This produces some redundancy in the code as most amino acids are encoded by more than one codon. One codon, AUG serves two related functions: it signals...
