Homoarginine as marker for exogenous protein
Absorption and secretion of free homoarginine in the intestine: when 9 mmol homoarginine were infused into the proximal part of the jejunum, there was a 99.9% disappearance of the free amino acid homoarginine up to the ileum. In addition, following the infusion of 9 mmol homoarginine into the vena jugularis less than 0.2% of the infused homoarginine appeared in the intestine.
We concluded from these data that with the homoarginine method endogenous protein in the chyme of the intestine can be distinguished from the food protein as homoarginine is not incorporated into endogenous secreta and free homo arginine is completely absorbed.

??

ChEBI: An L-lysine derivative that is the L-enantiomer of homoarginine.
