The fces of animals that live on vegetables contain neither excretin, butyric acid, nor cholesterin.
Such are the constituents, according to Harley, of the usual concretion, the cholesterin calculus.
They are largely composed of cholesterin, combined with small amounts of bile-pigments and acids, lime and magnesium salts.
The mucus is the colloid; cholesterin, lime, and soda salts are the crystalloids.
The mechanism of its formation is not unlike that of the cholesterin concretion.
Besides other agencies due to advancing life, the increase of cholesterin is an influential factor.
Fatty acids also appear to be present to some extent combined with cholesterin forming cholesterin esters (about 0.06%).
The liver also takes out from the blood a waste substance which has the formidable name of cholesterin.
In the former pigment, bile acids, and cholesterin may also be present.
Therefore he had treated with cholesterin the paraffin in his bucket, and this same cholesterin reappeared in the resulting glove.
white, solid substance present in body tissues, 1894, earlier cholesterin, from French cholestrine (Chevreul, 1827), from Greek khole "bile" (see cholera) + steros "solid, stiff" (see sterility). So called because originally found in gallstones (Conradi, 1775). The name was changed to the modern form (with chemical suffix -ol, denoting an alcohol) after the compound was discovered to be a secondary alcohol.
cholesterin cho·les·ter·in (kə-lěs'tər-ĭn)
cholesterol cho·les·ter·ol (kə-lěs'tə-rôl', -rōl')
A white crystalline substance found in animal tissues and various foods, normally synthesized by the liver and important as a constituent of cell membranes and a precursor to steroid hormones. Its level in the bloodstream can influence the pathogenesis of certain conditions, such as the development of atherosclerotic plaque and coronary artery disease.
A sterol found widely in animal and plant tissues. It is a main component of blood plasma and cell membranes, and it is an important precursor of many steroid hormones (such as the estrogens, testosterone, and cortisol), vitamin D2, and bile acids. In vertebrates, cholesterol is manufactured by the liver or absorbed from food in the intestine. Higher than normal amounts of cholesterol in the blood are associated with higher risk for developing coronary artery disease and atherosclerosis. Chemical formula: C27H46O. See also high-density lipoprotein, low-density lipoprotein.
A white soapy substance found in the tissues of the body and in certain foods, such as animal fats, oils, and egg yolks. Cholesterol has been linked to heart disease and atherosclerosis. (It collects on the walls of arteries and interferes with the flow of blood.) High levels of cholesterol in the blood are considered to be unhealthy. (See saturated fats, HDL, and LDL.)
