Concept explainers
(a)
Interpretation: The validation about the presence of a “head and two tails” structure in the given substance has to be predicted.
Concept introduction: The “head and two tails” model gives the orientation of groups in space. It has two parts, the head which is polar and the two tails, which are non-polar. The polar part of the model is soluble in water, so it is hydrophilic in nature. The non-polar part of the model is insoluble in water, so it is hydrophobic in nature.

C60H111O51 Use the following information to answer the following questions."The native structure of hemoglobin (HB) comprises of two α and two β subunits, each of which carries a heme group. There appear to be no previous studies that report the in-vitro folding and assembly of Hb from highly unfolded α and β globin in a 'one-pot' reaction. One difficulty that has to be overcome for studies of this kind is the tendency of Hb to aggregate during refolding. This work demonstrates that denaturation of Hb in 40% acetonitrile at pH 10.0 is reversible."
