Spectrophotometric determination of lipases, lysophospholipases, and phospholipases

open access: yesJournal of Lipid Research, 1984
Spectrophotometric techniques for determining the activities of lipases, lysophospholipases, and phospholipases are reviewed. These methods involve the use of thioester substrate analogs as well as omega-nitrophenyl derivatives of the corresponding ...

A systems-level model reveals that 1,2-Propanediol utilization microcompartments enhance pathway flux through intermediate sequestration. [PDF]

open access: yesPLoS Computational Biology, 2017
The spatial organization of metabolism is common to all domains of life. Enteric and other bacteria use subcellular organelles known as bacterial microcompartments to spatially organize the metabolism of pathogenicity-relevant carbon sources, such as 1,2-

Supercooled Liquid Dynamics Studied via Shear-Mechanical Spectroscopy

open access: yes, 2008
We report dynamical shear-modulus measurements for five glass-forming liquids (pentaphenyl trimethyl trisiloxane, diethyl phthalate, dibutyl phthalate, 1,2-propanediol, and m-touluidine).

Hydrothermal stability of Ru/SiO2-C: A promising catalyst for biomass processing through liquid-phase reactions [PDF]

open access: yes, 2016
In this work, structural and morphological properties of SiO2-C composite material to be used as support for catalysts in the conversion of biomass-derived oxygenated hydrocarbons, such as glycerol, were investigated in liquid water under various ...

Engineering transcriptional regulation to control Pdu microcompartment formation.

open access: yesPLoS ONE, 2014
Bacterial microcompartments (MCPs) show great promise for the organization of engineered metabolic pathways within the bacterial cytoplasm. This subcellular organelle is composed of a protein shell of 100-200 nm diameter that natively encapsulates multi ...

Juçara Fruit (Euterpe Edulis Martius) Valorization Combining Emergent Extraction Technologies and Aqueous Solutions of Alkanediols

open access: yesMolecules, 2023
Anthocyanins from juçara fruits were extracted by pressurized liquid extraction (PLE) or ultrasound-assisted extraction (UAE), using aqueous solutions of 1,2-alkanediols and glycerol ethers as biobased solvents.

Multiple solvent signal presaturation and decoupling artifact removal in 13C{1H} nuclear magnetic resonance [PDF]

open access: yesMagnetic Resonance, 2020
The analysis by proton-decoupled carbon-13 nuclear magnetic resonance spectroscopy of samples dissolved in solvents presenting strong multiple resonances can be facilitated by the suppression of these resonances by multisite presaturation.

Esters of (S)-1,2-propanediol and (R,R)-2,3-butanediol — Chiral Compounds Inducing Cholesteric Phases with a Helix Inversion · [PDF]

open access: yes, 1987
Mesogenic chiral esters of optically active (S)-1,2-propanediol and (R,R)-2,3-butanediol were synthesized. The compounds, added to a nematic phase induce cholesteric phases exhibiting a helix inversion with temperature variation.

Structure and Expression of Propanediol Utilization Microcompartments in Acetonema longum [PDF]

open access: yes, 2014
Numerous bacteria assemble proteinaceous microcompartments to isolate certain biochemical reactions within the cytoplasm. The assembly, structure, contents, and functions of these microcompartments are active areas of research. Here we show that the Gram-
