Cyclohexane-1,4-diammonium dithiocyanate

In the title salt, C6H16N22+·2CNS−, the cyclohexane ring adopts a chair conformation. In the crystal, N—H...N hydrogen bonds encloseR42(8) rings involving two N atoms from the cyclohexane-1,4-diammonium cations as donors with the N atoms of two thiocyanate anions as acceptors. The crystal structure is further stabilized by intermolecular N—H...S hydrogen bonds that combine with these contacts to form a three-dimensional network.

Role of non-covalent interactions in the production of visco-elastic material from zein

The role of non-covalent interactions in the formation of visco-elastic material from zein was investigated. Hydrophobic interactions were evaluated through the addition of various salts from the Hofmeister series. Urea, ethanol, and beta mercaptoethanol (β-ME) were used to evaluate the effects of protein denaturation and disulfide bonds on zein's ability to form a visco-elastic material. The addition of NaI and NaSCN altered the properties of visco-elastic materials made from zein, making them softer and more extensible, as did urea and ethanol. The addition of NaCl and Na2SO4 negatively impacted the ability of zein to from a visco-elastic material and at higher concentrations completely disrupted the formation of visco-elastic material. These results indicate that manipulating non-covalent interactions in zein can alter and in some cases, completely disrupt the formation of a visco-elastic material. Specifically this may be due to disruption of hydrophobic interactions within individual zein proteins or interactions between proteins. The reducing agent β-ME had little effect on zein's ability to form a visco-elastic material. Therefore, the visco-elastic properties of zein arise as a result of non-covalent interactions.
