Optimization of lipase-catalyzed sorbitol monoester synthesis in organic medium

open access: yes, 2000
The influence of acid/polyol molar ratio and reaction time on lipase-catalyzed esterification of oleic acid (OA) and sorbitol was studied to determine optimal conditions for monoester synthesis.

The genome‐wide response of Dermatophagoides pteronyssinus to cystatin A, a peptidase inhibitor from human skin, sheds light on its digestive physiology and allergenicity

open access: yesInsect Molecular Biology, Volume 33, Issue 6, Page 662-677, December 2024.
The genome of Dermatophagoides pteronyssinus was screened for genes encoding peptidases (n = 320), glycosylases (n = 77), lipases and esterases (n = 320), peptidase inhibitors (n = 65) and allergen‐related proteins (n = 52). Ingestion of cystatin A caused the regulation of cysteine endopeptidases and glycosylases, genes acquired by horizontal gene ...

Development of Phosphonate Monoester-Based Coordination Frameworks

open access: yes, 2018
This thesis emphasizes the development and gas sorption properties of metal-phosphonate monoester compounds. The first chapter discusses hydrolytic stability in metal-organic frameworks, with a focus on the types of hydrolytic exposure and assessing ...

Recent Insights and Future Perspectives on Promiscuous Hydrolases/Acyltransferases

open access: yes, 2021
Promiscuous hydrolases/acyltransferases have attracted attention for their ability to efficiently catalyze selective transacylation reactions in water to produce esters, thioesters, amides, carbonates, and carbamates.

Organogels with Fe(III) Complexes of Phosphorus-Containing Amphiphiles as Two-Component Isothermal Gelators

open access: yes, 2016
The properties of thermally reversible organogels in which the gelators consist of a phosphonic acid monoester, phosphonic acid, or phosphoric acid monoester and a ferric salt are probed by IR and NMR spectroscopies, optical microscopy, X-ray diffraction,

Effects of guanidino acetic acid and betaine supplementation on growth, dietary nutrient digestion and intestinal creatine metabolism in sheep

open access: yesVeterinary Medicine and Science, Volume 10, Issue 4, July 2024.
Dietary supplementation of rumen‐protected betaine on top of guanidino acetic acid in sheep diets can improve the apparent digestibility of ether extract, phosphorus and creatine levels in small intestinal mucosal tissues. Additionally, supplemental feeding of rumen‐protected betaine and guanidino acetic acid may promote growth and development of sheep

Chiral-Phosphoric-Acid-Catalyzed C6-Selective PictetSpengler Reactions for Construction of Polycyclic Indoles Containing Spiro Quaternary Stereocenters

open access: yes, 2022
Compared with the well-established asymmetric Pictet–Spengler reactions on the pyrrole ring of indoles, the catalytic asymmetric Pictet–Spengler reaction on the benzene ring of indoles has been rarely studied.

Why a d-β-hydroxybutyrate monoester? [PDF]

open access: yes, 2020
Much of the world's prominent and burdensome chronic diseases, such as diabetes, Alzheimer's, and heart disease, are caused by impaired metabolism. By acting as both an efficient fuel and a powerful signalling molecule, the natural ketone body, d-β ...
