Water - Coggle Diagram
Water
Simple structure
- The unshared negative electrons on the oxygen atom give a slight negative charge.
- This makes water a polar molecule - it has a partial negative charge on one side and a partial positive charge on the other side.
- The shared negative hydrogen electrons are pulled towards the oxygen atom. The other side of each hydrogen atom is left with a slight positve charge.
- The negatively charged oxygen atoms of one molecule attract the positively charged hydrogen atoms on another molecule.
- A molecule of water is one atom of oxygen joined to two atoms of hydrogen by shared electrons.
- This attraction is called hydrogen bonding.

Useful properties
Good solvent
Water is polar, the positive end of a water molecule will be attracted to the negative ion, and vice versa.
-
A lot of important substances in metabolic reactions are ionic. This means they are made from one positively and one negatively charged atom or molecule.

Useful properties
Metabolite
-
A hydrolysis reaction requires a molecule of water to break a bond. A condensation reaction produces a molecule of water as a new bond is formed.
