Question
The products of the saponification of a fat are? A) fatty acids and glycerol. B) phospholipids C) salts of fatty acids D) salts of fatty acids and glycerol E) the esters of fatty acids Bile salts are synthesized from? A) cephalin B) triacyl glycerols C) pancreas D) lecithin E) cholesterol Cholesterol belongs to the _____ group of lipids. A) steroid B) prostaglandin C) triacylglycerol D) wax E) phospholipid Bile salt are stored in the? A) gall bladder B) small intestine C) pancreas D) stomach E) liver Bile salts are among the lipid class known as? A) steroids B) prostaglandins C) triacyl glycerols D) cerebrosides E) sphingosides A precursor of prostaglandins is _____ acid. A) linoleic B) palmitic C) oleic D) tauric E) arachidonicExplanation / Answer
39) D) Salts of fatty acids and glycerol
In saponification, the triglyceride is treated with a strong base (e.g., lye), which accelerates cleavage of the ester bond and releases the fatty acid salt and glycerol.
40) E) Cholestrol
Bile salts are synthesized from Cholestrol. They are synthesized in the liver, stored in the gallbladder, secreted into the duodenum, and finally, for the most part, reabsorbed in the ileum.
41) A) Steroid.
It is a sterol (or modified steroid), a type of lipid molecule, and is biosynthesized by all animal cells. The molecule has a number of ring structures and is similar in shape to other steriods like testesterone and estrogen.
42) a) Gall bladder
Bile salts are are synthesized in the liver, stored in the gallbladder, secreted into the duodenum, and finally, for the most part, reabsorbed in the ileum.
43) A) Steroids
Bile salts constitute a large family of molecules, composed of a steroid structure
44) E) Arachadonic acid.
Eicosanoids is the general nomenclature for the type of molecules that prostaglandins and leukotrienes are catagorized as.
