“…2). Our previous findings [61][62][63][64]20,21,65] using 2-mercapto-propionylglycine (MPG) and the more recent results using alpha lipoic acid [3,11,34,39,47,50,66,68], could, at least in part, become explained by reversible blockade (R-S-MPG; R-S-LA), of reactive sulfhydryl groups at strategic membrane sites including the ATPsynthase with excessive reversible reactivity of the Fo b subunit preserving mobility and structure changes during ATP synthesis.…”
