Abstract
In this research, unzipped sulfanilic acid inspired hydrophobic peptide tube was synthesis by increasing the polarity of sulfanilic acid through nucleophilic attachment of aniline which then provided two reactive sites at the S-terminus. These two sites were then attached with the N-terminal of valine and alanine respectively at an intensity of 1000-1600 of 11 2θ (°). Through π-π stacking at the side chains, the opened ended peptide was linearly arranged to form the unzipped tube. Fourier transform infrared spectroscopy (FTIR) confirm the amine bond formation whiles X-ray diffraction test results confirmed D-spacing 7.36 and 4.44 corresponding 2θ (°)12 and 19.97 respectively whiles the torsion angles (Ø2) conformations was between-150.5°and-169.2° and-2 between-129.0° and-150.6°. The Thermogravimetric analysis result showed an increase in the rigidity of the bond with an increasing intensity. Finally, Differential scanning calorimetry (DSC) test was carried out to confirm the crystallinity of the structure. Keywords: Sulfanilic acid, hydrophobic Peptide, Unzipped tubes, Nanomaterial
