Here's the structure of lactic acid:
O

HO - XXX - C - OH
Draw the structure of part of the polymer chain in PLA which is polylactic acid
My answer is
O O
|| ||
O - XXX -C -O - XXX -C
where XXX = rectangular box.
Also, here's one question
After use materials made from PLA are rapidly broken down by a variety of microorganisms. Suggest the products of this decomposition
thanks
Organic compounds are mostly broken down into CO2 and water.if not wrong.
My poly FYP was a test of the amount of CO2 produced by biodegradable polymers to research whether they are really biodegradable anot and its rate of breakdown.
