**1.2 Vegetable oil / fatty acid based supramolecular structures**

Even though supramolecular assemblies from above said molecules are in reports with varied hypothetical explanation, however, still the story behind the assembly of biological molecule is unclear. To understand the theory of self-assembly and supramolecular formation, researchers initiated the self-assembly studies using fatty acids and its derivatives. Montarnal et al., (2008) reported self-healing supramolecular rubber like material using vegetable oil, unsaturated fatty acid derivatives, combined with diethylene triamine and urea. Vegetable oil based supramolecular organogel is synthesized by Rogers et al., (2007). Chen et al., (2005) prepared supramolecular nanocapsules by electrostatic interaction between fatty acids palmitic acid and polyethylenimine. A mixture of fatty diacid and triacid is condensed first with diethylene triamine and then reacted with urea giving an oligomeric supramolecular self-assembled thermoreversible rubber having selfhealing property (Cordier et al. 2008). Novales et al., (2008) reported self-assembly of fatty acids and hydroxyl derivative salts to form supramolecular assembly.

Maximum reported supramolecular assemblies involve complete synthetic or hybrid systems and or semi biological system. Complete biological means of supramolecular assemblies demand more time and the process of synthesize is a challenging task.
