Biomolecules Questions and Answers

Draw a triacylglycerol (triglyceride) made from glycerol, myristic acid [CH, (CH₂),,COOH), palmitic acid [CH,(CH₂),COOH), and oleic acid [CH, (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.
