Protein digestion, amino acids, digestive enzymes, nutritional quality — in this episode of Proteinology, we explore what really happens inside your body when you eat a protein.

After understanding what a protein is and discussing your protein needs with François Mariotti, it's time to tackle a fundamental step: how your body digests proteins to release the amino acids that will build your own.

In this episode:

— The digestive tract in 4 stations: mouth, stomach, small intestine, colon

— The role of hydrochloric acid and pepsin in the stomach

— The enzyme cascade in the small intestine: trypsin, chymotrypsin, elastase, carboxypeptidases

— What the microbiota does with protein residues in the colon

— PDCAAS and DIAAS: how digestion defines the nutritional quality of a protein

Difficulty level: 4/10 — accessible to all, even without a scientific background.

Proteinology is the first bilingual scientific media dedicated to protein science — from fundamental research to the plate.
