Chapter 26, Problem 26.30P

Interpretation Introduction

Interpretation:

The hydrophobic and hydrophilic regions of a lecithin have to be identified.  Also, the region with which oils interact in making mayonnaise and interaction of water has to be identified.

Concept-Introduction:

Hydrophobic:

• Hydrophobic means repelling of water molecules. Hydrophobic molecules are insoluble in water and non-polar in nature.
• Due to its non-solvation, hydrophobic molecules aggregate in polar solvents like water.
• This aggregation of hydrophobic molecules leads to membrane formation, surfactant action, protein folding, and protein-protein recognition.

Hydrophilic:

Hydrophilic molecules tend to attract water molecules. These are water soluble and mostly polar in nature.
