• Protein levels of structure

  Primary structure is a polypeptide sequence of amino acids

  Secondary structure is polypeptide chains: Alpha helix and the beta pleaded sheet

  Tertiary structure is a polypeptide coiled up folded on its self

  Quaternary structure is when two or more polypeptides chains join together
• Denaturation is and caused by

  The unfolding of a protein

  High heat, Extreme pH and solvents
• Building blocks of carbohydrates

  Monosaccharides

  Disaccharides

  Polysaccharides
• Different types of Lipids

  Neutral fats

  Triglycerides

  Saturated (single double bond)

  Unsaturated (two double bonds)

  Phospholipids
• Monomer vs. Polymer

  Monosaccharide -> Carbohydrate

  Glycerol, fatty acids, steroids -> Fats (Lipids)

  Amino acids -> Proteins

  Nucleotides -> Nucleic acid
• Composition of cell membrane

  Glycerophospholipid, phosphate group and two fatty acid chains
• Function of protein

  Structural support, biochemical catalyst, fundamental to structure and function of living things
• Purines vs Pyrimidines

  Purines are two ringed: A and G

  Pyrimidines are one ringed: T, C and U
