This chapter presents an overview of lysine hydroxylation and cross-linking of collagen, and the analytical methods we have developed. Key words Installing hydroxyl groups into organic compounds can be effected by various metal catalysts. Many such catalysts are biomimetic, i.e. they are inspired by or intended to mimic enzymes such as cytochrome P450. Whereas many hydroxylations insert O atoms into C−H bonds, some reactions add OH groups to unsaturated substrates. The Sharpless dihydroxylation is su…
