WebApr 13, 2024 · Currently, no crystalline structures have been reported for the binding of curcumin to human SIK3. Additionally, the T-loop conformation of SIK3 of curcumin during its binding is also unclear. Therefore, in this study, both the open and closed T-loop conformations (SIK3-C and SIK3-O) were considered. WebThe majority of covalent bonds form between atoms of nonmetallic elements Diatomic molecules (H2, N2, F2, O2, I2, Cl2, Br2) exist because the two-atom molecules are more stable than the individual atoms The most stable arrangement of atoms exists at the point of maximum net attraction, where the atoms bond covalently and form a molecule
