Chapter 25: Q32P (page 1152)

An optically active fat, when completely hydrolyzed, yields twice as much stearic acid as palmitic acid. Draw the structure of the fat.

Short Answer

Expert verified

Structure of optically active fat is shown below:

Step by step solution

01

hydrolysis of optically active fat

Different fatty acids undergo hydrolysis reaction with hydroxyl group of glycerol results triesters of glycerol. Thus, fats and oils are triesters of glycerol which contain long chain fatty acids. The asymmetric carbon present in fat makes it optically active and it contains palmitic component at C1, C2 position Whereas, at C3 stearic component present.

02

Structure of optically active fat

The C2 carbon present in triglyceride is asymmetric and so, it is optically active.

Diethylstilbestrol (DES) was given to pregnant women to prevent miscarriage, until it was found that the drug caused cancer in both the mothers and their female children. DES has estradiol activity, even though it is not a steroid. Draw DES in a way that shows that it is structurally similar to estradiol.
