C) Micelles
D) Glycoside linkages
E) Enzymes

Question

Quizplus · Accepted Answer

Phospholipids are esters of glycerol, like fats, but contain only two fatty acids instead of three. The third hydroxyl group of glycerol is esterified with a phosphate group and a polar head group, which gives phospholipids their amphipathic nature and ability to form cell membranes. Saponifications is a process in which fats are hydrolyzed by a strong base to yield soap and glycerol. Micelles are structures formed by the aggregation of amphipathic molecules in aqueous solution, such as bile acids or detergents. Glycoside linkages are specific types of covalent bonds that occur between a sugar molecule and another molecule, usually a nitrogen or oxygen atom. Enzymes are proteins that catalyze biochemical reactions.
