Constituent of haemoglobin
What is phosphate used for
Making nucleotides

Water
It is a polar molecule
Oxygen end has negative charge
Hydrogen atoms have positive charge
Uneven distribution of charge is called a dipole
When two water molecules are close in contact the opposing charges attract each other and form ?
Hydrogen bond
Individual hydrogen bonds are …
Weak
Many hydrogen bonds are …
Form a lattice like framework which is much stronger this attraction is called cohesion
Term dipole
Polar molecule which has positive and negative charge separated by very small distance
What are the properties of water
