Schema: Monomeric protocollagen chains trimerize, the propeptides are cleaved off and the collagen molecules self-assemble to microfibrils and fibrils. Oxidation of lysine and hydroxylysine by lysyloxidase initiates the formation of the various natural enzyme-derived crosslinks [62, 508]. a Atomic force microscopic image (AFM) of reassembled collagen (dried); b AFM image and c scanning electron microscopic image of dried porcine skin splits (dried). AFM and REM images were prepared by Diana Voigt and Ralf Bittmann, FILK
