Which of the following can be absorbed without being digested in the alimentary canal?

Biomacromolecules in food like proteins (e.g., albumin), carbohydrates (e.g. starch) and fats (e.g., tripalmitic acid) cannot be utilised by our body in their original form. They have to be broken down and converted into simple substances in the digestive system. Vitamins (e.g., Calciferol) and minerals are micromolecules and can be absorbed directly into blood without being digested.
