Which of the following are almost always hydrophobic?

• carbohydrates

• lipids

• proteins

• nucleic acids

Answer explanation

Hydrophobic molecules are molecules that do not interact well with water. Examples of hydrophobic molecules include nonpolar molecules such as hydrocarbons (e.g. oils, fats, waxes), halogenated hydrocarbons (e.g. chloroform, carbon tetrachloride), and some organic compounds (e.g. steroids, terpenes).
