What are carbohydrates? O Water is non-polar which is why other compounds will dissolve in it
O Macromolecules composed of amino acids
O Non-water soluble macromolecules with a high proportion of hydrocarbons
O Macromolecules composed of nucleotides

O Non-water soluble macromolecules with a high proportion of hydrocarbons

Explanation:

Carbohydrates are one of the four biological molecules in nature (asides from proteins, nucleic acid, and lipids). Carbohydrates are a complex polymer consisting of several chains of carbon and hydrogen (hydrocarbons).

According to this question, carbohydrates are non-water soluble macromolecules with a high proportion of hydrocarbons.
