When soaps disperse in water,the long hydrocarbon tails cluster together in a hydrophobic ball,while the ionic heads on the surface of the cluster stick out into the water.These spherical clusters are called:
A)fatty acid esters
B)triacylglycerols
C)lipid bilayers
D)micelles

Question

Quizplus · Accepted Answer

The described structure of hydrocarbon tails clustering together and the ionic heads sticking out into the water is characteristic of micelles. A is incorrect because fatty acid esters do not necessarily form spherical clusters in water. B is incorrect because triacylglycerols do not have ionic heads on their structure. C is incorrect because lipid bilayers consists of two layers of phospholipid molecules, not a single cluster.
