• Time Remaining: 07:06:38

Which component of a phospholipid gives it nonpolar characteristics?

Glycerol molecule

MY ANSWER

A glycerol molecule is hydrophilic due to the presence of electronegative oxygens.

Hydrogen bonds

Hydrogen bonds are formed between hydrogen and an electronegative atom, indicating polarity.

Phosphate group

A phosphate group is hydrophilic due to the presence of electronegative oxygens.

Carbon-hydrogen chains

Carbon-hydrogen chains do not have electronegative atoms and confer nonpolarity on the tails of phospholipids.
