Possible Interaction: Carnosine and Glycylglycine

“ Glycylglycine produced a significant impairment in the mean rate of histidine absorption from carnosine (P less than 0-01).”

“ Glycylglycine uptake was significantly decreased in the presence of L‐phenylalanylglycine or carnosine.”

“Jejunal uptake of carnosine was inhibited by equimolar glycylglycine , glycylglycylglycine, glycylsarcosine, glycylproline, methionylmethionine and prolylhydroxy-proline but not by the equivalent free amino acids, or by a mixture of β-alanine and histidine.”
