Concept explainers
(a)
To determine: The structure of cholic acid that shows the rings in their chair conformations, and each methyl group and hydroxyl group as axial and equatorial.
Interpretation: The structure of cholic acid that shows the rings in their chair conformations, and each methyl group and hydroxyl group as axial and equatorial is to be stated.
Concept introduction: Cholic acid is also known as natural or primary bile acid that is insoluble in water but soluble in acetic acid and alcohol.
(b)
To determine: The structure of the cholic acid-glycine combination and an explanation corresponding to the given statement that cholic acid-glycine is a good emulsifying agent.
Interpretation: The structure of the cholic acid-glycine combination and an explanation corresponding to the given statement that cholic acid-glycine is a good emulsifying agent is to be stated.
Concept introduction: The nature of cholic acid-glycine combination is similar to the nature of soap and detergent. The cholic acid-glycine has highly polar head and slightly polar tail.
