It has been observed that like the fully hydrated PC/FA and 1,2,-B-GalDAG/FA mixtures, the phase behaviour of fully hydrated 1,2-B-D-XyloDAG/FA 1:2 is also quite different both from the phase behavour of fully hydrated pure 1,2=B-XyloDAG, and of pure fatty acid. The fully hydrated 1,2B-XyoDAG with chainlengaths C[12] - C[14] exhibit lamellar (L[b]) and H[11] phases, and those with chainlengths C[16] - C[19] Exhibit lamellar  (L[b]), H[11] and inverse micellar Fd3m phases[1]. whereas the fully hydrated 1,2-B-DXyloDAG/FA 1:2 mixtures with C[16] - C[18] tend to form mainly lamelalr L[b] and inverse micellar Fd3m cubic phases. The mixture with a chainlength of C[19] was found to adopt the lamellar ([b]) phase and a novel, presumbley inverse micellar cubic phase, which has not yet been indexed[1].</td></tr></tbody></table> ER -
