Bonds in all the right placesGlycosylation of proteins can stabilize folding intermediates and thus enable the total synthesis of correctly folded disulfide-rich proteins.doi:10.1038/s41570-022-00365-xDavey, Stephen G.Nature Publishing Group UKNature Reviews Chemistry...
At high temperatures the breaking of chemical bonds becomes relatively easy and the slow step in a chemical reaction shifts to the rate at which energy can seep into the bond that is to break. This has been observed by various investigators. A new general theory of reactions is developed here...

Why do we hybridize atomic orbitals to explain the bonding in covalent compounds? Describe the formation of a covalent bond in H2 from atoms. What does it mean to say that the bonding electrons are shared by the two atoms? For single bonds between similar types...

The highest-energy stereoisomer of 1,2,3,4,5,6-hexafluorocyclohexane, in which all of the fluorines are 'up', is prepared in a 12-step protocol. The molecule adopts a classic chair conformation with alternate C-F bonds aligned triaxially, clustering three highly electronegative fluorine atoms...
