Proteins are made of amino acid chains, or polypeptides. Amino acids have a basic backbone made of an amino group and a carboxyl group, and differ in their side-chains. These polypeptide chains of ...

Experimental evidence of long-range attractive forces between cellular proteins has been obtained by researchers in France more than 50 years after the idea was first proposed. The forces are mediated ...

What is a Surface Force Apparatus (SFA)? The Surface Force Apparatus (SFA) is a highly sensitive scientific instrument used to measure the forces between two surfaces at the nanoscale. It allows ...

The alkanes are a homologous series with a structure based on a carbon chain - each carbon atom forms four covalent bonds The intermolecular forces vary between molecules, so different organic ...

For a car to accelerate there has to be friction between the tire and the surface of the road. The amount of friction generated depends on numerous factors, including the minute intermolecular forces ...

Scientists have been asking that question of the limber little gecko for at least 75 years. These scaly climbers can scuttle nimbly across a polished glass ceiling. In a pinch, they can hang by one ...

Compared with alkanes, alcohols have significantly higher boiling points. The hydroxyl groups in alcohol molecules are responsible for hydrogen bonding between the alcohol molecules. As greater energy ...
