We have conducted the first search for the lowest-energy conformation of interstellar glycine. We have detected an emission line in Sgr B2 which is coincident in frequency with the J/sub K/ -K+ = 14/sub 1,ts14/ -13/sub 1,ts13/ transition of conformer I glycine, but other transitions have not yet been found. While the carrier of the observed line is uncertain, we know of no other frequency-coincident species and, hence, cannot rule out glycine. We have identified several previously unidentified interstellar lines as methyl formate and discuss the evidence for the existence of the elusive interstellar ethylene oxide - the only reported interstellar ring-structured molecule. Five unidentified interstellar lines were found.
