Draw a triacylglycerol (triglyceride) made from glycerol, myristic acid [CH3(CH2) 12COOH], palmitic acid[CH3(CH2)14 COOH], and oleic acid [CH3(CH2),CH=CH(CH2),COOH(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.SelectDrawTemplatesMoreEraseCHо
