Interpretation:
The specific rotation of enantiopure cholesterol and the fraction of synthetic cholesterol in the given mixture are to be determined.
Concept introduction:
The specific rotation, denoted by
Where
The optical purity is equal to the percentage enantiomeric excess, which can be determined from the following expression:
The percent enantiomeric excess is the difference between the percentages of major and minor enantiomers.
A racemic mixture is the mixture of equal composition of enantiomers.

- Organic Chemistry 1 Here is the professor's solution to the problem. However, I do NOT understand the solution. Please explain the answer in a clear step-by-step fashion to me. Explain the answer provided in the image in a clear fashion and as if I did not know much about organic chemistry. It seems to me like the professor is making the problem more complicated than it has to be. Can you demystify or simplify this problem about D glucose? How can you assign priorities on a Fischer projection? I don't get it.arrow_forwardOrganic Chemistry 1 Here is the professor's solution to the problem. However, I do NOT understand the solution.

Please explain it in a basic way.arrow_forwardA certain compound has a specific rotation of -43.2o (c = 5, toluene). What is the observed rotation of a sample of 1.24 g of the enantiomer of this compound when diluted to a concentration of 1.00 g ml-1 in the same solvent? Example 30 In his classic studies of stereochemistry and optical activity in organic compounds, Pasteur measured the optical activity of many solutions. For the naturally occurring enantiomer of tartaric acid, [α]D20 = +12.4o (c = 20, H2O).

The rotation of this solution increases over time to the same equilibrium value as that shown by the ?α anomer. A solution of one enantiomer of a given monosaccharide rotates plane‑polarized light to the left (counterclockwise) and is the levorotatory isomer, designated (−). The other enantiomer rotates plane‑polarized light to the same extent but to the right (clockwise) and is the dextrorotatory isomer, designated (+). An equimolar mixture of the (+) and (−) forms does not rotate plane‑polarized light. The optical rotation, the number of degrees by which plane‑polarized light rotates on passage through a given path length of a…arrow_forwardThe structure of 4 isomers of an aldotetrose carbohydrate are given. 1) select every structure that is a diastereomer of structure D A, B, or C? 2) select every structure that is a enantiomer of structure C D, B, or A? 3) select every structure that is a stereoisomer of structure D A, B, or Carrow_forward
