Polyhydroxyalkanoates (PHAs) are natural, linear, thermoplastic polyesters synthesized by micro-organisms as intracellular carbon reserves and ion sinks in response to limited nutrient availability and imposed stress conditions. We bio-synthesized PHB and deuterated PHB (d-PHB) and performed SANS on the dilute solutions of these molecules. In this paper, we report the conformational properties of PHB and d-PHB in d-chloroform and chloroform, respectively.
