Question: page 2 2 a the helix to coil transition of...

Question details

Page 2 2. (A) The helix to coil transition of an alanine peptide in water has been observed using numerous experimental techniques, which includes standard calorimetry. The two conformations of neighboring peptide groups in a polypeptide are shown to difer in energy by iu3 k.walmo. A oey fhempeoruilationhof emperature what is the expected ratio of populations of the two conformations? (B) How do you expect the population of o conformations to change over that standard temperature range of water (0C to 100°C)? The 1.3 kcal/mol per residue was determined from the following journal article: Scholtz, J., et. al., Proc. Natl Acad. Sci. USA, 88, 2854-2858 (1991). There are numerous other journal articles on the helix to coil perspectives and determine the variation in the experimentally determined energy. [Put a box around your numerical answer in part-A. For part-B, the recommended way to illustrate the answer is through a plot of population versus temperature.]
