19. Which of the following statements about hydropathy plot is false?
(A) A hydropathy plot for a protein is a graphical representation of the average "hydropathy" values of contiguous groups of amino acid R-groups in a protein.
(B) A hydropathy plot can be used to deduce the quaternary structure of a membrane protein.
(C) Integral membrane proteins usually contain one or more regions with a high hydropathy index.
(D) A hydropathy plot can be used to predict whether a given protein sequence contains membrane-spanning segments.
(E) It is possible to get hydrophobic areas for proteins that are not membrane associated in a hydropathy plot, as water soluble proteins have hydrophobic interiors.
