The acid lipase of the castor bean. Properties and substrate specificity*

open access: yesJournal of Lipid Research, 1962
A castor bean lipase with a pH optimum of 4.3 is found within the fatty layer obtained by centrifuging a homogenate of the bean; most of the fat may be removed by extraction with ethyl ether in the presence of saturated sodium chloride solution, yielding

A Small Phospholipase A2-α from Castor Catalyzes the Removal of Hydroxy Fatty Acids from Phosphatidylcholine in Transgenic Arabidopsis Seeds1[OPEN]

open access: yesPlant Physiology, 2015
A castor phospholipase is involved in editing ricinoleic acid from the membrane lipids in transgenic Arabidopsis seeds. Ricinoleic acid, an industrially useful hydroxy fatty acid (HFA), only accumulates to high levels in the triacylglycerol fraction of ...

Biolubricant basestocks from chemically modified ricinoleic acid

open access: yesJournal of King Saud University - Science, 2012
AbstractThis paper presents a series of chemically modified biolubricant basestocks derived from ricinoleic acid. The reactions were monitored and products were confirmed by NMR and FTIR. The synthesis protocol is carried out in three stages: (1) epoxidation of ricinoleic acid; (2) synthesis of 10,12-dihydroxy-9-acyloxystearic acid from epoxidized ...

Synthesis of Novel Benzothiazolium Ionic Liquids and Research on Their Catalytic Esterification for Ricinoleic Acid

open access: yes, 2016
Four new task-specfic benzothiazolium ionic liquids (ILs) [HBth]HSO4, [HBth]H2PO4, [HBth]ClO4, [HBth]NO3 were synthesized and characterized by NMR and FT-IR, which bear the proton acid groups based on low price benzothiazole as raw material.
