✦ Synopsis

The solubthty of oxygen m dlpalmltoylleclthm (DPL) and paraffin C19 has been investigated by measurement of the enhanced proton relaxation rates under the influence of oxygen pressure The paraffin shows a noticeable effect m the rotator phase, but not so m the crystalhne phase In contrast to paraffins both phases of DPL-bdayers dissolve oxygen, but the solubdlty m the hqu~d-crystalhne phase ~s greater than m the crystaUme state by a factor ~3 Furthermore, the expenments indicate a distribution of electron relaxation tunes m the crystalhne phase m contrast to the hquld-crystaUme phase A possible explanation of this behavlour is a mulhphase structure of the "crystaUme" lameUae The biological relevance of these results could be a tnggermg of the gas-transport by the alveolar hmng of lungs, ff cychc phase transitions occur during the breathing-cycle
