Dr. Margert is developing a chemical product that reduces the accumulation of lipids in the brains of children with Niemann-pick type C1 disease. She assumes her product is pure based on the measurements of physical properties such as boiling point and melting point. Unfortunately, clinical studies have shown that, in some cases, her chemical results in severe seizures and migraines. Which of the following is the most likely explanation? O The product contains enantiomers which have similar physical properties but different chemical properties. O The product is pure, but it is affecting people differently based on their alleles. O The product contains contaminants of a different chemical compound O The product contains a mixture of cis and trans isomers which have the same physical properties but different chemical properties.

(please type answer).

Glucose-1-phosphate has a ΔG°′ value of −20.9 kJ/mol, whereas that for glucose-6-phosphate is −12.5 kJ/mol. After reviewing the molecular structures of these compounds, explain why there is such a difference in these values.
