Chetana, You need to look at the structure of these residues. Several amino acids, notably Asp and Asn can i to i sidechain to backbone h-bond. For those two it typically occurs in the alphaL conformational space (what David was alluding to), which is why Asp and Asn are (relatively) often found there.
