Cholesterol is usually synthesized in animals and smaller cholesterol can be generated in plants. They are important in the composition of cell membranes and also steroid hormones.

Synthesis of the thyroid hormones is controlled by the actions of the anterior pituitary hormone, thyroid stimulating hormone (TSH).
