Question

The relationship between steroid hormone, estrogen and the peptide hormone, insulin, is being investigated. In order to quantify the levels of each of these hormones, tissue samples were homogenized then placed in a mixture of 2:1 hexane/water. What's the expected results from this extraction method?
a. estrogen would be in the hexane phase; insulin would be in the aqueous phase
b. both estrogen and insulin would be in the aqueous phase
c. insulin would be in the hexane phase; estrogen would be in the aqueous phase
d. both estrogen and insulin would be in the hexane phase

Answer 1

Answer:

Option (A).

Explanation:

Estrogen hormone is important for the regulation of the female menstrual cycle and their growth and development. Insulin is an important hormone that regulates the blood glucose level.

The hormones insulin and estrogen is placed in the mixture of 2:1 hexane/water. Insulin is hydrophilic molecule and can easily dissolce in water. Estrogen is a hydrophobic molecules and easily dissolve in hexane.

Thus, the correct answer is option (A).
