Depending on the particular chemistry the precipitate may or may not settle. Precipitation occurs when a <i>medium</i> in which a substance had previously been absorbed/dissolved, suffers a change so that the substance can no longer be supported in suspension.
Cholesterol is a soft, waxy substance found in all of your body's cells. Your body needs it in order to work properly. This is because your body uses cholesterol to hold cells together. Your body also uses it to make hormones, vitamin D, and substances that help you digest foods.holesterol is a soft, waxy substance found in all of your body's cells.

The liver is central to the regulation of cholesterol levels in the body. Not only does it synthesize cholesterol for export to other cells, but it also removes cholesterol from the body by converting it to bile salts and putting it into the bile where it can be eliminated in the feces. Two types of lipoproteins are triglyceride-rich: the chylomicrons and VLDL. 2  Chylomicrons are synthesized by enterocytes from lipids absorbed in the small intestine. 3  VLDL is synthesized in the liver. 4  The function of these lipoproteins is to deliver energy-rich triacylglycerol (TAG) to cells in the body (pink pathway).
