Is protein absorbed by the large intestine?

No, protein is not absorbed by the large intestine. The majority of protein digestion and absorption occurs in the small intestine. The small intestine has specialised structures called villi and microvilli that increase the surface area for absorption and contain enzymes that break down proteins into smaller peptides and amino acids. Once digested, these peptides and amino acids are absorbed through the villi into the bloodstream.

The large intestine is mainly involved in water absorption, electrolyte balance, and the formation and storage of faeces. It does not play a significant role in protein absorption.
