Question

which is a component of a phospholipid?
carbon ring
hydrophilic head
long - chain alcohol
amino acid

Explanation:

Phospholipids have a hydrophilic head and hydrophobic tails. The hydrophilic head contains a phosphate - group which is attracted to water. The other options are not components of phospholipids. A carbon ring is not a characteristic component, long - chain alcohol is not a main part, and amino acids are components of proteins, not phospholipids.

Answer:

hydrophilic head
