Webb15 jan. 2024 · Protein digestion starts at the mouth and will continue, to a lesser extent, in the large intestine. Notably, amino acids are hydrophilic, or “water-loving,” and will, therefore, require some help passing through the lipid barrier of our cells. They will generally follow primary active transport where an ATP molecule will be expended.
