Imagine that a scientist reexamines the crystallographic work that established the absolute configuration of (+)-tartaric acid and finds that the structure of this compound is the mirror image of the one given in Eq. 24.56. What changes would have to be made in Fischer’s structure of D-(+)-glucose?
