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.

The team used a combination of sonification, visualization, and physics calculations to understand how the hydrogen bonds contributed to the folding and unfolding of the protein. Based on their ...

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 are composed of one or more chains of amino acids, which are linked together by peptide bonds and folded into specific three-dimensional structures. Proteins have four levels of structure: ...

Free RNA nucleotides form hydrogen bonds with ... the correct shape and becomes a protein. Peptide bonds form between the adjacent amino acids to finalise the structure.

The structure of the β-sheets is strengthened by hydrogen bonds, which remain stable throughout the functional life of the ...
