Treatment of a polypeptide with 2-mercaptoethanol yields two polypeptide chains (see *sequences* 1 and 2 below). What disulfide bonds exist in the intact polypeptide? Note that the disulfide bonds are both BETWEEN the two peptides, NOT within.

Both josef loschmidt and amedeo avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios. neither scientist discovered “avogadro’s number” in the form we use it today (6.02 x 10 23). still, there’s a controversy over the name. research the contributions from these two scientists and read about how avogadro’s number got its name. briefly state what you think this number should be called, providing key details of each scientist’s contributions to this concept and a solid rationale for your case in naming the number.
