Hydrogen bonds are often first met in biology - Proteins, DNA where the emphasis is not on the bonding - students think that it is a full bond with a hydrogen. Students may have not met the orbital ...

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.

This base-to-base bonding is not random ... Beyond the ladder-like structure described above, another key characteristic of double-stranded DNA is its unique three-dimensional shape.

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 ...

The structure of liquid water is therefore not ... This allowed them to measure the strength of individual hydrogen bonds and the strength of the neighboring bond at the same time.
