摘要：
H-1 NMR methods are described which allow direct studies of the Cys(34) binding site of albumin in intact human blood plasma in vitro, Antiarthritic gold drugs and the alcohol-aversive drug disulfiram induce a structural transition detectable via H epsilon 1 and H delta 2 resonances of His(3) of albumin, and reactions of cystine, glutathione and captopril in plasma have also been investigated, Contrary to most assumptions, little of the albumin in normal plasma appears to be blocked at Cys(34) as a cystine disulfide.
