What are the three types of bonds found in biological molecules? |
Covalent, ionic and hydrogen |
|
|
Describe covalent bonding |
Atoms share a pair of electrons between their outer shells completing both of the atoms outer shells, this forms a compound known as a molecule |
|
|
Describe ionic bonding |
Ions with opposite charges attracted one another, the electrostatic attraction is the ionic bond |
|
|
Describe hydrogen bonding |
The electrons within a molecule spend more time at one position causing the region to be more negatively charged, this molecule is a polar molecule. The negative region of one polarised molecule and the positively charged region of another polarised molecule attract. |
