Question

Which one of the following is an amine hormone?
A) Insulin
B) Progesterone
C) Thyroxin
D) Oxypurin

Answer 1

Hint:Hormones are the molecules synthesized in the specific region of the body and are transported to the different body parts to regulate the function in the body.Based on the from which they are derived there are three basic types of the hormones which are 1) lipid-derived, 2) amino derived, 3) peptide derived.Testosterone, Insulin, Estrogen, Progesterone, Thyroxin, cortisol, prolactin, etc are examples of some hormones.

Complete answer:
Here, we have to determine the hormone which is amine derived.
Insulin is the peptide hormone secreted by the pancreas. It maintains the glucose level in the blood and stores the glucose in the liver, fat, and muscles.
As it is a peptide hormone it contains protein molecules and is also called protein hormones.
Therefore, option (A) Insulin is incorrect.
Progesterone is the steroid hormone that belongs to the class of lipid hormones. It plays a very important role in pregnancy and the menstrual cycle and is also called sex hormone.
As it is lipid hormone option (B) is also an incorrect hormone.
Thyroxine is an important hormone secreted by the thyroid gland into the bloodstream. It maintains the insulin level in the body. It is an amino derived hormone therefore; option(C) Thyroxine is the correct answer to the given question.
Here, option (D) oxypurin is also an incorrect answer to the question.
Hence,the correct option is C.

Note:Hormones are very important to regulate the different functions in our body. In the various parts of our body, different glands secrete different hormones which regulate specific function in our body.The lipid-derived amino acids are derived from cholesterol hence their structure is similar to it and it is also called steroid hormones. These are soluble in water and are longer than the peptide hormones.
The amine derived hormones derived from thee and tryptophan are relatively small.
Peptide hormones contain small peptide chains that are water-soluble but lipid insoluble.
