here is one clue.. mostly, amino acids exist as L-amino acids.... so, enzymes usually cut L-amino acids....

Peptidoglycan contains D-amino acids, which are different than the L-amino acids found in proteins. D-amino acids have the identical composition as L-amino acids, but are their mirror images. The use of D-amino acids is unusual in biology and bacteria have enzymes called racemases to convert between D and L forms specifically for this use.Due to the presence of D-amino acids, they cant be degraded by enzymes which generally act on L-amino acids.

absolutely right bro...

okay.. try this... a very gud one (taken from a book , not my original creation) ....

A man walks into a bar, offers to keep his head completely submerged in a bucket of water for twenty minutes and if he doesnt he will buy drinks all around and if he does the patrons must stand him a round of drinks. He does and so they do. The question is how did he do it?

and yes it's a medical condition that allows him to do this.

answers after 2 days.. till then, try answering...
