Because R and S enantiomers have equal but opposite optical activity, it naturally follows that a 50:50 racemic mixture of two enantiomers will have no observable optical activity. If we know the specific rotation for a chiral molecule, however, we can easily calculate the ratio of enantiomers present in a mixture of two enantiomers, based on its measured optical activity.

(Watch on YouTube: Optics 2. The racemic mixture is 7 % (+)-cholesterol and 7 % (-)-cholesterol. It will have zero optically activity, so all of the observed rotation comes from the 86 % natural cholesterol. The natural cholesterol then accounts for 86 % + 7 % = 93 % of the mixture.

I know that's disappointing because at the beginning of the semester I told you guys there's barely any numbers in this course, but this is one exception. There is this one topic and it's called optical activity.

Plane polarized light Two mirror images of a chiral molecule are called enantiomers or optical isomers. Pairs of enantiomers are often designated as "right-" and "left-handed".
