Researchers compared similar proteins from related organisms in different habitats. they found
that the proteins from organisms living in harsh environments had a greater number of cysteine
amino acids than did proteins from organisms not living in harsh environments. the structure of
cysteine is shown. bonds can form between the sulfur atom of different cysteine amino acids (s-s bonds)
which of the following best describes the effect of a greater number of cysteine amino acids on the
stability of the proteins?
