Question

Draw the repeat unit of the copolymer used for artificial skin growth, which is formed by condensation polymerization of lactic acid and glycolic acid

Answer 1

Answer:

On the attached document.

Explanation:

Hello,

Condensation polymerization reactions come from the reaction of two gathering organic chains to produce a polymer and water. In this manner, when lactic acid reacts with glycolic acid a break in the O-H bond of their carboxyl group is carried out in order to yield the monomeric unit which combines both lactate and glycolate. In addition to the aforesaid fact, the beginning of such polymer is given by the glycolate and the end by the lactate and water must be yielded as well. You can substantiate the previous description by checking out the the attached picture in which "n" refers to the repetition of the formed copolymer which is the product indeed.

Best regards.

Answer 2

Answer is in Word document below (x - number of units of lactic acid, 
y - number of units of glycolic acid).
PLGA is a copolymer of poly lactic acid (PLA) and poly glycolic acid (PGA). It is biocompatible and biodegradable copolymer.
