Polysaccharides	+Largest carbohydrate	+Starch, glycogen and celluose are examples	+Contains carbon, hydrogen and oxygen	+Composed of monosaccharide subunits	-Contains no carbon
Nucleic Acids	+It is a biomolecule that stores cellular information in the form of a code	+Subunits of nucleotides	+Organic compound need for life	+Formed from sugar molecule to phosphate to nitogenous	-Doesn't contain sugar
Lipids	+Made mostly of carbon, hydrogen and oxygen	+Glycerol is a threecarbon molecule that serves as a backbone for a lipid molecule	+Fats, oils and sweets	+Cells use lipids for energy storage	-Fatty acid is a long chain of amino acids
Proteins	+Composed of carbon, hydrogen, oxygen, nitrogen and sulfur	+Basic building blocks of protein are amino acids	+Proteins are also the building blocks of many structural components of organisms	+Provide structure for tissues and organs and carry out cell metabolism	-Aren't essential for life
