Figure 19.1.3.2

Sections of a neutron difference Fourier map showing methyl hydrogen densities for several representative methyl groups. No phasing information about the methyl hydrogens was included in the model; therefore, hydrogens should appear in the difference map at their true positions but at reduced density (∼ half weight). The groups shown are: (a) Ala24, (b) Thr21, (c) Thr28, and (d) Ala45.
