monomers/polymers

• what do all organisms contain?

  the same type of biological molecule/compound
• what theory does it support?

  evolution
• what contain which atoms?

  C , H , O , N
• define polymer?


  large molecule made of many repeating smaller molecules called monomer
• what bond joins monomers together?

  covalent bonds
• polysaccharide= polymer of glucose (e.g starch, glycogen, cellulose)
• proteins = polymer of amino acids
• nucleic acid = polymer of nucleotides (e.g dna , rna)
• condensation= bonds made and water is removed
• hydrolysis = bonds broken and water is added
