Given the following context and please only answer from the context "HDL are created by lipidation of apo A-1 synthesized in the liver and intestine. They have a number of functions, including: 1) serving as a cir- culating reservoir of apo C-II and apo E for chylomicrons and VLDL; 2) removing unesterified cholesterol from from peripheral tissues via ABCA1and esterifying it using lecithin:cholesterol acyl transferase (LCAT), a liver- synthesized plasma enzyme that is activated by apo A-1; and 3) delivering these cholesteryl esters to the liver (reverse cholesterol transport) for uptake via SR-B1. Cholesterol is the precursor of all classes of steroid hormones (glucocorticoids, mineralocorticoids, and sex hormones—androgens, estrogens, and progestins). Synthesis, using primarily cytochrome P450 (CYP) mixed- function oxidases, occurs in the adrenal cortex (cortisol, aldosterone, and androgens), ovaries and placenta (estrogens and progestins), and testes (testosterone). Each steroid hormone diffuses across the plasma mem- brane of its target cell and binds to a specific cytosolic or nuclear receptor.: "Extract the 'steroidal hormones' examples in bullet points that are mentioned in the context" DO NOT ADD EXTRA UNMENTIONED INFORMATION Limit your response to 300 words.
