Genetic control of sterol esterification in developing wheat endosperm [PDF]

, 1975
1. 1. The action of gene Pln, previously characterized by the sterol ester patterns of mature whole wheat kernels, has been found to be restricted to the endosperm and not to affect the embryo, the pericarp or the seed coat. 2. 2.

Characteristics of cellulose nanofibril films prepared by liquid- and gas-phase esterification processes

e-Polymers
Cellulose nanofibrils (CNFs) are versatile materials, but their sensitivity to humidity affects performance. Esterification with fatty acids enhances the hydrophobicity of CNF films.

Optimization of the Esterification Process of Crude Palm Oil (CPO) with Natural Zeolite Catalyst Using Response Surface Methodology (RSM)

Indonesian Journal of Chemical Research
Esterification is one of the important processes in the production of biodiesel. This is done to ensure that the FFA content in CPO is less than 3%. The esterification reaction can be accelerated by using natural zeolite as a catalyst.

Simulation of biodiesel production using hydro-esterification process from wet microalgae

MATEC Web of Conferences, 2018
Recently, algae have received a lot of attention as a new biomass source for the production of renewable energy, such as biodiesel. Conventionally, biodiesel is made through esterification or transesterification of oils where the process involves a ...

ZnO/ionic liquid catalyzed biodiesel production from renewable and waste lipids as feedstocks [PDF]

, 2019
A new protocol for biodiesel production is proposed, based on a binary ZnO/TBAI (TBAI = tetrabutylammonium iodide) catalytic system. Zinc oxide acts as a heterogeneous, bifunctional Lewis acid/base catalyst, while TBAI plays the role of phase transfer ...

Movement of 25-hydroxycholesterol from the plasma membrane to the rough endoplasmic reticulum in cultured hepatoma cells.

Journal of Lipid Research, 1995
Oxysterols serve as both substrates and signal molecules in the cholesterol-utilizing pathways of mammalian cells. Their distribution and movement within these cells, however, have not been well characterized; therefore we have undertaken such an ...

The effect of alcohol on the performance of lipase-immobilized enzymatic membrane reactor for esterification of (R,S)-ketoprofen [PDF]

, 2006
The effect of alcohols on the performance of lipase-immobilized enzymatic membrane reactor (EMR) for enantioselective esterification of (R,S)-ketoprofen has been studied. In this work, mixed solvent medium was used and the (R)-ketoprofen was reacted with
