Abstract:
The conjugation of tRNA with folic acid-chitosan conjugates was studied, using multiple spectroscopic methods and transmission electron microscopy (TEM). Thermodynamic analysis ΔH -14 to -10 (KJMol-1) and ΔS 14 to -1 (JMol-1, K-1) showed tRNA-folic acid-chitosan bindings occur via H-bonding, hydrophobic and van der Waals contacts. The loading efficacy and the stability of tRNA conjugates were enhanced as folic acid-chitosan size increased. TEM analysis showed major tRNA morphological changes, upon folic acid-chitosan conjugation. No alteration of tRNA conformation was observed on conjugate formation. Folic acid-chitosan conjugates can deliver tRNA in vitro.

A key example involves the conjugation of cyanide ions, which impair cellular respiration and alter hemoglobin into non-oxygen-carrying cyanmethemoglobin. To neutralize this threat, a sulfur atom from thiosulphate is transferred to the cyanide ion, catalyzed by the enzyme rhodanese, resulting in an inactive compound called thiocyanate.
