Polyhydroxybutyrate: Polyhydroxybutyrate (PHB) is a polyhydroxyalkanoate (PHA), a polymer belonging to the polyesters class that are of interest as bio-derived and biodegradable plastics.Frieder W.Polyester resin: Polyester resins are unsaturated synthetic resins formed by the reaction of dibasic organic acids and polyhydric alcohols. Polyester resins are used in sheet moulding compound, bulk moulding compound and the toner of laser printers.GHB receptor: The γ-hydroxybutyrate (GHB) receptor (GHBR), originally identified as GPR172A, is a G protein-coupled receptor (GPCR) that binds the neurotransmitter and psychoactive drug γ-hydroxybutyric acid (GHB).Chlorophyllase: Chlorophyllase (klawr-uh-fil-eys)chlorophyllase - Definitions from Dictionary.com is the key enzyme in chlorophyll metabolism.Osiris TherapeuticsAcyl-homoserine-lactone synthase: Acyl-homoserine-lactone synthase (, acyl-homoserine lactone synthase, acyl homoserine lactone synthase, acyl-homoserinelactone synthase, acylhomoserine lactone synthase, AHL synthase, AHS, AHSL synthase, AhyI, AinS, AinS protein, autoinducer synthase, autoinducer synthesis protein rhlI, EsaI, ExpISCC1, ExpISCC3065, LasI, LasR, LuxI, LuxI protein, LuxM, N-acyl homoserine lactone synthase, RhlI, YspI, acyl-[acyl carrier protein]:S-adenosyl-L-methionine acyltranserase (lactone-forming, methylthioadenosine-releasing)) is an enzyme with system name acyl-(acyl-carrier protein):S-adenosyl-L-methionine acyltranserase (lactone-forming, methylthioadenosine-releasing). This eHypotoniaAcetoacetic acidSpin–lattice relaxation in the rotating frame: Spin–lattice relaxation in the rotating frame is the mechanism by which Mxy, the transverse component of the magnetization vector, exponentially decays towards its equilibrium value of zero, under the influence of a radio frequency (RF) field in nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI). It is characterized by the spin–lattice relaxation time constant in the rotating frame, T1ρ.
