  • Teacher Demo
H.W. Finish A "phat" lab on FATS
AND
Finish Lipid portion of macromolecule info sheet:
          List the elements (as identified in the periodic table) that are found in all lipids.
          Write the word “Fats”
         Under this heading hand draw a molecular picture of a fat molecule (p. 47).  Label the Glycerol and the 3 Fatty Acid Tails.  Under your drawing write the function of fat molecules.
         Hand draw a saturated fatty acid tail.  Under the saturated fatty acid tail draw (or print) in color a picture of a food item that contains saturated fats.
         Hand draw an unsaturated fatty acid tail.  Under the unsaturated fatty acid tail draw (or print) in color a picture of a food item that contains unsaturated fats.
          Write the word “Phospholipids”
         Under your Phospholipids heading, hand draw a picture of a phospholipid (p. 204).  Label the phosphate head and the fatty acid tails.  Under your drawing write the function of phospholipids in your body.
          Write the word “Sterols”
         Under your Sterol heading, hand draw a molecular picture of a sterol (the 4 ringed fused structure from your notes.  Under your drawing write the  functions of  sterols in your body and give 2 examples.
