During war , accidents or street quarrels , sometime people get deep injuries which require stitching, of wounds. Earlier these wounds used to be stitched by nylon thread which was non - biodegradable. This thread used to be pulled out after healing of wounds. This process caused pain to the patients. But these days biodegradable polymer is used for stitching of wounds which gets degraded by itself , within a weak or so. Now answer the following questions : Write the name of the biodegradable polymer used for stitching of wounds after operation. (ii) What are the monomer units of this polymer ? (iii) What are the degradation products of this polymer and what happens to them in the body ?

1.	During war , accidents or street quarrels , sometime people get deep injuries which require stitching, of wounds. Earlier these wounds used to be stitched by nylon thread which was non - biodegradable. This thread used to be pulled out after healing of wounds. This process caused pain to the patients. But these days biodegradable polymer is used for stitching of wounds which gets degraded by itself , within a weak or so. Now answer the following questions : Write the name of the biodegradable polymer used for stitching of wounds after operation. (ii) What are the monomer units of this polymer ? (iii) What are the degradation products of this polymer and what happens to them in the body ?
Answer» Solution :(i) Name of the biodegradable polymer in nylon -2-nylon -6. (ii) The monomer units of this polymer are : `underset("GLYCINE")(H_(2)N-CH_(2)-COOH)` `underset("6 -Aminohexanoic acid")(H_(2)N-(CH_2)_(5)-COOH` (iii) The degradation products of this polymer are the monomer molecules themselves. These are either oxidation in the BLOOD to `CO_2` and `H_2O` or glycine MAY be used in the synthesis of PROTEINS needed by the body.
