Bile acids - from liver cells.
Steroid hormones _ from the adrenal glands.
Bile contain many types of salts, generally sodium salts of steroid acids. See the link below.
Cholesterol is the precursor of bile acid, steroid hormones and vitamin D.
Cholesterol is the principal sterol of vertebrate tissues, especially in brain, spinal cord, fats or oils, and an important precursor of bile acids and steroid hormones, such as progestins, glucocorticoids, mineralocorticoids, androgens, and estrogens.
Yes, vitamin D is derived from cholesterol.Hint: "Read your Physiology textbook.
Sterols
for steriods: lanosterol

steroids... The steroids are a group of lipids with no fatty acids. This group includes cholesterol, Bile Salts, and steroid hormones (which includes sex hormones).

Bile acids are steroid acids found predominantly in the bile of mammals. Bile salts are bile acids compounded with a cation, usually sodium. In humans, the salts of taurocholic acidand glycocholic acid (derivatives of cholic acid) represent approximately eighty percent of all bile salts. Bile acids, glycine and taurine conjugates, and 7-alpha-dehydroxylated derivatives (deoxycholic acid and lithocholic acid) are all found in human intestinal bile. An increase in bile flow is exhibited with an increased secretion of bile acids. The main function of bile acid is to facilitate the formation of micelles, which promotes processing of dietary fat
Cholesterol is a precursor for other important steroid molecules: the bile salts, steroid hormones, and vitamin D. -Gem :) http://www.ncbi.nlm.nih.gov/books/NBK22339/
It is used to produce hormones and cell membranes and is transported in the blood plasma of all mammals. It is an essential structural component of mammalian cell membranes. It is required to establish propermembrane permeability and fluidity. In addition cholesterol is an important component for the manufacture of bile acids, steroid hormones, and Vitamin D.
There are a few of them actually...cholesterol is one of them, so are sex hormones, bile salts and adrenal cortical hormones. They contain hydrocarbon rings. They are fat soluble and obtain little oxygen.
A bile acid is any of the steroid acids produced by the liver, such as cholic acid, which occur as bile in sodium salts and serve to neutralize the contents of the stomach as they enter the duodenum and to aid the emulsification and absorption of fats.
Bile acids are produced from cholesterol in the liver.
Steroids are made with a ring of carbon atoms. Cholesterol is a steroid made in animals only. From cholesterol some important chemical messengers are made, like male hormone testosterone and female hormone estrogen. Cholesterol is eaten in foods and made in the body.
