Water is an important constituent of biochemistry, the study of biological reactions.
Cells contain approximately 70-90% water.
Water molecules cling to each other due to hydrogen bonding.
Water plays a role as an important solvent and determines the pathway taken by the water.
Those molecules that can attract water are said to be hydrophilic.
Nonionized and nonpolar molecules that cannot attract water are said to be hydrophobic.
Water molecules are cohesive and adhesive.
Due to cohesion, water shows surface tension.
Water has a high heat capacity.
Water is not a linear molecule. It has a bent shape. This is because the highly electronegative oxygen pulls the electrons from the hydrogen closer and gains a partial negative charge. This makes hydrogen partially positive.
