Concept explainers
Interpretation:
The peptide hormone that triggers the milk secretion should be explained.
Concept introduction:
The steroid is categorized in the lipid. They are insoluble in water. It is used for signaling purposes. They are good for energy storage. The steroids are organic compounds containing four carbon rings. They are categorized as hormone or cholesterol, etc.

Answer to Problem 47A
The peptide hormone is oxytocin that triggers milk secretion.
Explanation of Solution
The milk secretion is triggered by the oxytocin peptide hormone. Hormones control the body function and the secretion of any type of liquid from the body.
The steroids are a type of lipid that is stored in the body, but hormones are stored in the body to regulate the function of the body. Just like oxytocin secrete from the body and it stimulated to the secretion of milk.
