Draw a triacylglycerol (triglyceride) made from glycerol, myristic acid [CH3(CH2)12COOH], palmitic acid [CH3(CH2)14COOH], and oleic acid [CH3(CH2)7CH=CH(CH2)7COOH(cis)]. Place palmitic acid at the middle position. Cis/trans isometry is graded -it may help to draw hydrogen atoms associated with the carbon atoms of the double bond.
