+# Digestion
+- Protein digestion begins in the stomach
+- Hydrochloric acid denatures food proteins and activates pepsin
+	- Gastric enzymes that break proteins down into smaller polypeptides
+- After polypeptides enter the small intestine, the pancreas secretes protein splitting enzymes.
+- Trypsin and chymotrypsin
+- Enzymes released by absorptive cells break down shortened peptides into dipeptides and tripeptides
+	- Two and three amino acids respectively
+- Amino acids are carried to absorptive cells by carrier systems
+- After absorption, amino acids enter the capillary of villus
+	- Travel to liver via hepatic portal vein
+	- Liver keeps some amino acids
+		- Release the rest into circulation
+- Protein turnover is the cellular process of breaking down proteins and recycling their amino acids.
+	- Endogenous is a source of nitrogen
