Concept explainers
(a)
Interpretation: The validation about the given mixture being classified as a fat or oil has to be predicted.
Concept introduction: PUFA means poly unsaturated fatty acids or those fatty acids which contain two or more carbon-carbon double bonds. MUFA means monounsaturated fatty acids. SFA means saturated fatty acids which contain only single carbon-carbon bonds.
(b)
Interpretation: The basis for the answer given in part a has to be explained.
Concept introduction: PUFA means poly unsaturated fatty acids or those fatty acids which contain two or more carbon-carbon double bonds. MUFA means monounsaturated fatty acids. SFA means saturated fatty acids which contain only single carbon-carbon bonds.

- The molecular formula for glucose is C6H12O6. What would be the molecular formula for a polymer made by linking ten glucose molecules together by dehydration reactions? Group of answer choices A. C60H120O60 B. C60H102O51 C. C60H100O50 D. 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."
