44. What are bile salts?
(A) charged phospholipids
(B) amphipathic cholesterol analogs with detergent propertiese
(C) esterfied cholesterol
(D) hydrolyzed forms of triacylglycerol
Answers
Answer:
44.Bile acids are steroid acids found predominantly in the bile of mammals and other vertebrates. Diverse bile acids are synthesized in the liver. Bile acids are conjugated with taurine or glycine residues to give anions called bile salts. Primary bile acids are those synthesized by the liver. A. Phospholipids consist of a glycerol molecule, two fatty acids, and a phosphate group that is modified by an alcohol. The phosphate group is the negatively-charged polar head, which is hydrophilic. The fatty acid chains are the uncharged, nonpolar tails, which are hydrophobic .B.Amphipathic molecules are chemical compounds that have both polar and nonpolar regions, giving them both hydrophilic (water-loving) and lipophilic (fat-loving) properties. ... Examples of amphipathic molecules include cholesterol, detergents, and phospholipids. C. The esterified cholesterol formed in HDL is handed on to LDL, where it is incorporated into the non-polar core of the lipo- protein molecule. Low-density lipoprotein, carrying its load of cholesteryl ester, reaches the liver where the cholesteryl esters are hydrolys
D. Once in circulation, triacylglycerol is hydrolyzed before crossing the plasma membrane of peripheral cells. The primary enzyme that hydrolyzes triacylglycerol in plasma is lipoprotein lipase. Lipoprotein lipase hydrolyzes triacylglycerol into free fatty acids and 2-monoacylglycerol.
Answer:
(a) option is correct charged phospholipids
