The present invention provides novel biocompatible macromonomers, hydrogels, methods of synthesis and methods of use thereof. The biocompatible hydrogels of the present invention are prepared using native chemical ligation (NCL), in which a thioester readily reacts with a N-terminal thiol (cysteine) through transesterification and rearrangement to form an amide bond through a five-member ring intermediate.
