are sugars and starches are classified as lipids
Sugars and starches are, in fact, not lipids, but rather carbohydrates. Of the four biological macro molecules (carbohydrates/polysaccharides, proteins, nucleic acids, and lip â¦ ids), lipids are hydrophobic (not water soluble), less easily metabolized, and waxy or slippery to the touch.n contrast, sugars and starches are energy storying molecules and are soluble in water, which is consistent with the definition of a carbohydrate.
