Amino Acids Categorization - (Apr/17/2008 )
I know that amino acids are categorized in several way, for example polar or non-polar, hydrophobic or hydrophilic, etc. Can anybody give me an exact categorization in an uniform way? I mean that given an amino acid, can we say is it polar, or hydrophobic, etc?
Take away the arg, lys, glu, asp and his which are well known polar, all others are more or less hydrophobic. Asn, gln, ser and the, trp, tyr have less hydrophobicity than the rest because of amide and OH groups. all the others should be very hydrophobic ones.
