Synonym: Hydrazide PEG Lipoic acid,  Lipoic acid-PEG-CONHNH2, LPA-PEG-CONHNH2.

Description:

Lipoic acid PEG Hydrazide (Lipoic acid-PEG-CONHNH2) is one of Nanocs carbonyl reactive PEG derivatives that have a lipoic acid group on one end of PEG and a hydrazide group (-NHNH2) on the other terminus. Lipoic acid, also known as thioctic acid, contains a disufide bond that can bind to gold and other metal surface. It is also an important molecule parting in various biological processes. Hydrazide group (-NHNH2), on the other hand, can react with aldehyde or ketone groups derived from polysaccarides or glycoproteins. Reaction between hydrazide and ketone group results in a stable hydrazone bond, which is more stable than the schiff base formed between amine and ketone group.
