WebApr 25, 2024 · The breaking of a peptide bond is by the process of amide hydrolysis. Hydrolysis is the adding of water. In the presence of water, the peptide bonds break spontaneously to release energy. This property of breaking spontaneously in the presence of water is what leads to the naming of the peptide bonds as metastable. WebSep 20, 2024 · Here, the sugar groups of GM1 form hydrogen bonds with the peptide, thereby reducing the possibilities for other hydrogen bonds to otherwise form. In contrast, the dimerization in the aqueous phase is characterized by a random coil to β-sheet transition, leading to β-sheet structures similar to the ones found in A β fibrils.
