Notes from ap bio class

• Biological molecules


  Four different types: nucleic acids, proteins, lipids, carbohydrates
• Monomers


  Small building blocks that make up biological molecules
• Lipids


  • Not made up of monomers, single monomer
  • Make up cell membranes
  • Good source of energy
  • Generally non-polar but can have polar parts
• Nucleic acids

  • DNA and RNA
  • Building blocks are nucleotides (sugar, phosphate, nitrogenous base)
