Module 3 Study Assignment The Stability of Tyrosine Spring 2010- CHEM XXI *This is to be turned in on Friday, Feb. 19 th at the beginning of class. Before you turn it in, you must get it signed off by a preceptor. See D2L for a list of preceptors and their respective office hours. 1) Let’s evaluate the decomposition of the amino acid tyrosine. The simulation below models the decomposition reaction shown. http://www.chem.arizona.edu/chemt/Flash/decomposition.html
