Question

Select the true statements about eicosanoids. a. Eicosanoids are broken down within seconds to inactive residues. b. Arachidonic acid, a C20 fatty acid, is the precursor to eicosanoids. c. Eicosanoids are transported in the blood stream to their site of action. d. Eicosanoids are responsible for producing pain and fever. e. High concentrations of eicosanoids are necessary for effective action.

Answer 1

Answer: the true statements about eicosanoids includes options A,B,D,E

Explanation:

EICOSANOIDS are mostly produced from the precursor arachidonic acid, a C20 polyunsaturated fatty acid. They are broken down within seconds to inactive residues after synthesis.High concentrations of eicosanoids are necessary for effective action.The three major types of eicosanoids includes:

-prostaglandins,

- thromboxanes, and

- leukotrienes.

Depending on the above types mentioned, they play a role in inflammation, pain, fever promotion, blood pressure regulation, and blood clotting. They also influence the immune response and certain respiratory and reproductive processes.

However, eicosanoids are NOT transported in the blood stream to their site of action RATHER they exert their effects on the tissue where they are synthesized.

Answer 2

Eicosanoids is a molecule that is made by the enzyme or other polyunsaturated fatty acid. They are a  subcategory of oxylipins that are the oxidized fatty acids in carbon units of lengths.

• The Eicosanoids include the PG, TX, LT, LX molecules always act on the cells that produce them. These Eicosanoids are broken within seconds to inactive molecular residues.

• Arachidonic acid reparents the C20 fatty acid, which is a precursor to eicosanoids. Eicosanoids are known for producing pain and fever. High concentrations of eicosanoids are essential for effective action.

Hence the option A, B, D, E are correct.
