  • 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.
