Carbon
Hydrogen
Oxygen
Nitrogen
Monosaccharide
Disaccharide
Polysaccharide
Carbon readily makes four stable bonds, in single, double or triple configurations.
Carbon is a very dense & heavy element, giving living things stability.
Carbon is the least electronegative non-metal
Carbon has a high affinity for Oxygen & Hydrogen, which make bonds easily with C
Oxygen has six outer valence electrons, and makes up to 2 bonds
Oxygen is highly electronegative; it is an 'electron hog', sharing them unevenly
The uneven sharing of electrons results in Oxygen forming polar covalent bonds
The presence of oxygen in Carbohydrates makes them highly insoluble in water
