Amylomaltases in Extremophilic Microorganisms

open access: yesBiomolecules, 2021
Amylomaltases (4-α-glucanotransferases, E.C. 2.4.1.25) are enzymes which can perform a double-step catalytic process, resulting in a transglycosylation reaction. They hydrolyse glucosidic bonds of α-1,4′-d-glucans and transfer the glucan portion with the

How Well Can You Tailor the Charge of Lipid Vesicles? [PDF]

open access: yes, 2019
Knowledge and control of surface charge or potential is important for tailoring colloidal interactions. In this work, we compare widely used zeta potential (ζ) measurements of charged lipid vesicle surface potential to direct measurements using the ...

Antiviral nucleoside diphosphate diglycerides: improved synthesis and facilitated purification.

open access: yesJournal of Lipid Research, 1992
Cytidine diphosphate diglyceride and its analogs have previously been synthesized by condensing phosphatidic acid with the monophosphomorpholidates of the various nucleosides. Yields have been low and purification of the product has been difficult.

Femtomole analysis of 9-oxononanoyl cholesterol by high performance liquid chromatography1

open access: yesJournal of Lipid Research, 1998
9-Oxononanoyl cholesterol, a cholesterol core-aldehyde formed during lipoprotein oxidation, was recently identified in advanced human atherosclerotic lesions. Here we present a rapid and sensitive HPLC method for 9-oxononanoyl cholesterol analysis.
