Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which term best describes the fatty acid tails of phospholipids?
A
Hydrophobic (Water-Fearing)
B
Hydrophilic (Water-Loving)
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -So, the correct answer is ‘Hydrophobic and consist of two fatty acid tails, one that is saturated and another that is unsaturated’

Detailed explanation-2: -Each phospholipid is amphipathic, with two hydrophobic tails and a hydrophilic head. The hydrophobic tails face inward towards one another, and the hydrophilic heads face outwards.

Detailed explanation-3: -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.

Detailed explanation-4: -The “tail” of the molecule is made up of two fatty acids, which are hydrophobic and do not dissolve in water. Following the rule of “like dissolves like", the hydrophilic head of the phospholipid molecule dissolves readily in water.

Detailed explanation-5: -1: A phospholipid consists of a head and a tail. The “head” of the molecule contains the phosphate group and is hydrophilic, meaning that it will dissolve in water. The “tail” of the molecule is made up of two fatty acids, which are hydrophobic and do not dissolve in water.
