When are ketone bodies produced in the body?

Short Answer

Expert verified

ketone bodies produced in the body when glucose is not readily available.

Step by step solution

01

Step 1:Given information

We have been find out when ketone bodies produced in the body.

02

Step 2:Explanation

Ketone bodies, also known as ketones, are molecules produced by the liver during the gluconeogenesis process, which creates glucose during fasting and hunger.

When glucose is scarce, the liver creates ketone bodies, which are used as a source of energy in the peripheral nervous system. The most prevalent ketone molecules are acetoacetate (AcAc) and 3-beta-hydroxybutyrate, whereas acetone is the third and least frequent. Ketones are always present in the blood, although their levels spike during fasting and vigorous exercise. They're also found in the blood of newborns and pregnant women.
