The effect of head groups on the thermodynamic properties and morphological features of the domains formed in the Langmuir monolayers at 10 oC has been investigated by a film balance and a Brewster angle microscopy (BAM). 2-hydroxyethyl myristate (2-HEM) and n-tetradecanoyl N-ethanolamide (NHEA-14), having the same chain length but different head groups have been taken as amphiphiles. Both the amphiphiles represent a first-order LE-LC phase transition at 10 oC at the air-water interface. The critical surface pressure necessary for this phase transition is 6.0 mN/m for 2-HEM and 1.0 mN/m for NHEA-14. The surface morphologies of the domains are entirely different. The domains of 2-HEM are circular having internal texture, while those of NHEA-14 are dendritic having directional characteristics. The presence of interfacial hydrogen bonding in the latter amphiphile should be responsible for the formation of such characteristic domains in the case of latter amphiphile.

Phospholipid Monolayer

AbstractThe precipitation of calcium oxalate monohydrate (COM) was observed at biphasic phospholipid Langmuir monolayers with the aid of Brewster angle microscopy. COM appears preferentially at phase boundaries of a monolayer of 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) in a state of liquid expanded/liquid condensed coexistance. However, when the phase boundary is created by two different phospholipids that are phase segregated, such as DPPC and 1,2-dimiristoyl-sn-glycero-3-phosphocholine (DMPC), crystal formation occurs away from the interface. It is suggested that COM growth at phase boundaries is preferred only when there is molecular exchange between the phases.
