Proteins and sugars are water soluble, but fats are not. This means that they cannot be broken down and absorbed in the same way as proteins and sugars, which can be dissolved in the watery contents of the digestive tract. Fats require special emulsification and solubilization in bile salts before they can be broken down by enzymes and absorbed.
