The chemistry of amino acid side chains is critical to protein structure because ... side chains can form ionic bonds, and polar amino acids are capable of forming hydrogen bonds.

Hydrogen bonds are key constituents ... at strategic points in the structure. Reinforcement at key topological contacts may be a general principle to protect protein folds against destabilization ...

getting caught in a loop of wrong hydrogen bonds that prevented correct folding before the right bonds took over for the final protein structure. There were also “Highways,” where the correct bonds ...

Hydrogen bonds form between two atoms and a hydrogen ... Intramolecular Bonding in Proteins IB Biology Play How is the Tertiary Structure of Proteins Formed? The tertiary structure of proteins ...

This structure makes protein-based materials as strong as steel, even though the hydrogen bonds that hold them together are 100 to 1,000 times weaker than the metallic bonds in steel. Researchers ...

The prediction of protein structure is difficult for a few reasons ... because proteins typically have hundreds of hydrogen bond “donors” (often oxygen) that should be close to hydrogen ...

Image from Gray’s Anatomy Hair’s chemical structure, it turns out ... that can form between adjacent keratin proteins, a hydrogen bond, is much weaker and temporary, with hydrogen bonds ...

This provides compelling evidence that the cations can structure the hydrogen bonding network. Their work appears in Nature Chemistry. While the exact nature of the molecular effects of solvation ...

The structure of protein sets the foundation for its interaction ... N-H groups in the backbone form a hydrogen bond with the C=O group of the amino acid 4 residues earlier in the helix.
