Document Summary
Protein structure and function: pick a letter to match the amino acids in the left column with the appropriate side-chain type from the right column. Ser (1) nonpolar, aliphatic (2) nonpolar, aromatic (3) basic (4) polar, uncharged (5) acidic: given a peptide with the following amino acid sequence: Match the following amino acids with the descriptions that apply to their side chains. Pick the corresponding letters (a-j, above) and write them on the appropriate line(s) below. Note: some of the descriptions may not apply to any of the amino acids, and some may apply to more than one of the amino acids. What is the major difference between the hydrogen bonds that stabilize secondary and tertiary structure? b). What is the major structural difference between myoglobin and hemoglobin? c). Why is proline not found in elements of regular secondary structure, such as an -helix? d). Which level of protein structure is sometimes stabilized by metal ion chelation? e).
