In the structure of oL-glutamine (3,5-diamino-5-oxo-pentanoic acid, C5H10N203), the molecules aggregate into double layers involving head-to-tail sequences stabilized by hydrogen bonds between main-chain atoms. The double layers are stacked along a with the help of hydrogen bonds between side-chain atoms. This pattern is fundamentally different from that in the structure of L-glutamine, but is very similar to those in the structures of oL-methionine and hydrated L-arginine o-glutamate. The essential features of different possible aggregation patterns of amino acids appear to be determined by interactions involving main chain atoms.
