Enzymic synthesis of the iron-sulfur cluster of spinach ferredoxin.
The anti-glycation capacity of lipoicacid combined with its capacity for hydrophobic binding enables lipoicacid to prevent glycosylation of albumin in the bloodstream.
Lipoicacid is known to biochemists as being part of a prosthetic group (lipoamide) of the dihydrolipoamide acetyltransferase portion of the pyruvate dehydrogenase enzyme complex that converts pyruvate to Acetyl-CoA prior to entry into the citric acid cycle.
Lipoicacid is also beneficial in reducing ischemic-reperfusion injury by direct action as well as by glutathione protection and xanthine oxidase inhibition [FREE RADICAL BIOLOGY and MEDICINE; Packer, L.; 19(2):227-250 (1995)].
