HUMAN NUTRITION

Detailed explanation-1: -Simple carbohydrates are small polar molecules, containing several –OH functional groups, which makes them hydrophilic (they dissolve well in water).

Detailed explanation-2: -With their numerous polar hydroxyl groups, simple sugars are quite hydrophilic and very soluble in water.

Detailed explanation-3: -The major difference is that carbohydrates are polar and hydrophilic so it dissolves easily in water. Lipids are nonpolar and hydrophobic so it does not mix with water. OH bonds in carbs make it hydrophilic. Lipids lack the OH bonds.

Detailed explanation-4: -Carbohydrates and proteins are water-soluble macromolecules of nutritional significance.
