WebJul 4, 2024 · Proteins are folded and held together by several forms of molecular interactions. The molecular interactions include the thermodynamic stability of the complex, the hydrophobic interactions and the disulfide bonds formed in the proteins. The figure below (Figure 2) is an example of protein folding. Figure 2: Protein Folding. WebThe misfold is caused by a small aberration in the protein, and is an alternative stable configuration. Thus, it is an error that occurs, and may actually happen even without the prion, but the prion destination increases the chance of CJD. Sponsored by TruthFinder Have you ever googled yourself?
