The same LASSS treatment also conferred nitration resistance with a greater effect for Y198 than Y250, indicating a novel mechanism independent of an anti-oxidative function of LASSS
GLP-1 (7-36) has a short half life of less than 2 minutes, and like GIP, is rapidly degraded by the enzyme dipeptidyl peptidase IV (DPP-4), which is widely expressed in a number of sites, including the endothelial cells of small gut arterioles
