Which is the amphipathic organic compound

[From: ] [author: ] [Date: 12-03-31] [Hit: ]
eg.(c) Phospholipids have hydrophilic phosphate heads and hydrophobic fatty acid tails.......
(a) Oligosaccarides
(b)Proteins
(c) Phospholipids
(d) Nucleotides

and Why ?

-
All four compounds are organic, so it's not a trick question. :)

An amphipathic compound or molecule is one that has two different affinities: one end is hydrophilic and one end is hydrophobic (see link to definition below).

The correct answer is: (c) Phospholipids.

The lipid tail is hydrophobic, and the head is hydrophilic. This causes phospholipids to spontaneously form lipid bilayers in water, with the lipid tails lining up next to one another, and the heads facing outward toward the water. See the second link below for everything you ever wanted to know about phospholipid bilayers.

-
a molecule, such as a detergent, which has both hydrophobic and hydrophilic groups.
eg.(c) Phospholipids have hydrophilic phosphate heads and hydrophobic fatty acid tails.
