Methionyl-tyrosine is a dipeptide consisting of the amino acids methionine and tyrosine.[1] Methionyl-tyrosine has been detected, but not quantified in, a few different foods, such as birds in the anatidae family, chickens (Gallus gallus), and domestic pigs (Sus scrofa domestica). It is expected to form during digestion of protein.[2]
A crystalline monohydrate is known. In a water solution and solid form, it exists as a zwitterion where one proton is transferred from the -OH group to the -NH2, yielding -O− and -NH3+.[3]
