Question

Where are lipid-like steroidal hormones synthesized in animal cells?

Answer 1

Steroidal hormones:

1. Steroid hormones are a group of hormones derived from cholesterol that act as chemical messengers in the body.
2. The lipid-like steroidal hormones in animal cells are synthesized in the smooth endoplasmic reticulum and also mitochondria.
3. The smooth endoplasmic reticulum has no ribosomes attached to it , hence, is responsible for production of steroid hormones in the adrenal cortex and endocrine glands.
4. As they are made of lipids , they cannot mix with the the plasma of cell and are made to transport proteins and bind to it.

Example : Testosterone and progesterone are the steroid hormones.
