Chitosan Liposomal microspheres for Ricinoleic acid Encapsulation

Preparation and Characterization of Chitosan Poly(acrylic acid) Magnetic Microspheres

Spherical microparticles, capable of responding to magnetic fields, were prepared by encapsulating dextran-coated Fe3O4 nanoparticles into chitosan poly(acrylic acid) (PAA) microspheres template. The obtained magnetic microspheres were characterized by transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), X-ray powder diffra...

The Biosynthesis of Ricinoleic Acid.

1. Ricinoleic acid is shown to be synthesized in the immature castor bean seed only after 3-4 weeks from the time of fertilization. 2. Synthesis occurs both in the isolated embryo and the endosperm. 3. Linoleic acid does not act as precursor of ricinoleic acid in the isolated bean embryo. 4. Oleic acid is shown to be the direct precursor of ricinoleic acid. 5. The reaction does not use molecula...

Incorporation of ricinoleic acid into glycerolipids.

The coenzyme A thiol ester of ricinoleic acid was synthesized and characterized. Ricinoleoyl-CoA has been tested as an acyl donor in several in vitro systems using rat liver microsomal acyltransferases. It is essentially inactive when I-acylor z-acyl-sn-glycerol-3-phosphoryl choline are used as acceptors, however, it can serve as acyl donor when glycerol-3phosphate or I-acyl-sn-glycerol-3-phosp...

Screening of Castor Genotypes for Ricinoleic Acid Content

Castor (Ricinus communis L.) is an important non-edible oilseed crop of Euphorbiaceae family. Castor has enormous significance in the country as it plays an important role in the agricultural economies because it enables them to earn substantial foreign exchange through export of castor beans and oils. It is believed that castor is indigenous to the southeastern Mediterranean Basin, Eastern Afr...
