a hydrogen atom, and a variable component called a side chain (see below). Within a protein, multiple amino acids are linked together by peptide bonds, thereby forming a long chain. Peptide bonds ...

Their report, published in the Proceedings of the National Academy of Sciences, offers an unprecedented view of the sequence of hydrogen-bonding events that occur when a protein morphs from an ...

For their analysis, the team focused on hydrogen bonds, which are weak bonds that the protein forms internally between the atoms in its amino acids and with the water surrounding it. These bonds are ...

Computational analysis provides new insights into silk's mechanical properties that was unavailable experimentally ...

The cuticle is your hair’s protective outer layer, and when it’s healthy, it’s smooth and flat. Damage can lift some of the ...

New simulations show stretching during spinning causes the protein chains within the fibers to align and the number of hydrogen bonds between those chains to increase. Both factors increase the ...

Complementary hydrogen bonding interactions guide the molecules ... to transport ions across the lipid bilayer. Ion channel proteins are concerned with inorganic ion transport, which is crucial ...

Protein folding is the process by which proteins ... that fold rapidly, stabilized by hydrogen bonding and disulphide bridges, and then tertiary structure. For decades, research on Alzheimer ...

These include wobble base pairs, such as G-U and I-A (inosine-adenine), which have a slightly different geometry and hydrogen bonding pattern. Non-Watson-Crick base pairs can play important roles in ...

Proteins can further fold and assemble into complex structures, such as α-helices and β-sheets, which are stabilized by various interactions, including hydrogen bonds, disulfide bridges, and ...
