Biology secondary structure bonds
WebMost proteins have one highly stable tertiary structure, which is often organized around a core region of hydrophobic residues. However, if you denature proteins (e.g. by heating them up) and then let them cool they usually fail to reform into the 'correct' structure - instead they stick to each other. WebMay 4, 2024 · 2.

WebTo form a bond with the one prime. With the one prime carbon and I drew it that way because it kind of does bend. The whole molecule's going to have to bend that way to form this structure. And then when it forms that bond the carbon can let go of one of these double bonds and then that can, then the oxygen, the oxygen can use that.
