Dexon (below) is a polyester that is spun into fibers and used for surgical stitches that dissolve overtime, eliminating the need for a follow-up procedure to remove the stitches. The ester moieties are slowly hydrolyzed by enzymes present in the body, and in this way, the stitches are dissolved over a period of several months. Hydrolysis of the polymer produces glycolic acid, which is readily metabolized by the body. Draw the structure of glycolic acid. Identify a systematic name for glycolic acid. 

After the surgery, Maureen applies Indermil, which is a type of liquid bandage, to Robert s incision sites. Liquid bandages are tissue adhesives that seal surgical or wound incisions on a patient. Stitches and staples are not required and scarring is minimal. The polymer in a liquid bandage is typically dissolved in an alcohol-based solvent. The alcohol also acts as an antiseptic.
