Figure 1 (A) Area per lipid (APL) of the POPC and DOPC phospholipid bilayers as a function of time for one 110-ns simulation. (Solid green line) Experimental APL for POPC 66.0 Å2/lipid (47); (solid blue line) experimental APL for DOPC, 67.4 Å2/lipid (48). (B) The deuterium order parameters for the two-acyl chains of POPC and DOPC molecules in the system.

Figure 2 The density profile for the DOPC (A) and POPC (B) systems with 2.5-nm water layer. Water density (red), phospholipid density (black), and the di-mannose density (blue). The di-mannose density is amplified by 50 times to give better clarification. The Z axis is the direction perpendicular to the water-phospholipid interface (XY plane).

Figure 3 Characterization of residence time for di-mannose interaction with phospholipid for all the simulations of the DOPC and POPC systems with 2.5-nm water layer. Residence times are plotted against number of events (Event No.). Biophysical Journal 2013 104, 622-632DOI: (10.1016/j.bpj.2012.12.011) Copyright © 2013 Biophysical Society Terms and Conditions

Figure 4 Potential of mean force for di-mannose location in the DOPC system. The reaction coordinate is the distance in the z axis between center of masses of di-mannose and the phospholipid bilayer. (Inset) Location of di-mannose in the sugar membrane system at the energy minimum.

Figure 6 Sugar binding to the phospholipid bilayer as a function of sugar concentration. [M]local and [M]bulk correspond to the concentration of the dimannose close to the lipid bilayer (local) and in bulk solvent respectively.

Scheme 1 Schematic description of ligand diffusion in a box was used to derive an analytical expression for the binding rate constant for ligand binding with a 2-D surface. The red circle represents the ligand. Z=0 plane is an absorption plane, Z=L_z plane is a reflection plane and periodic boundary condition is applied in the x and y directions.
