Glucagon like receptor 1/ glucagon dual agonist acutely enhanced hepatic lipid clearance and suppressed de novo lipogenesis in mice. [PDF]

PLoS ONE, 2017
Lipid lowering properties of glucagon have been reported. Blocking glucagon signaling leads to rise in plasma LDL levels. Here, we demonstrate the lipid lowering effects of acute dosing with Glp1r/Gcgr dual agonist (DualAG).

A facile route for concurrent fabrication and surface selective functionalization of cellulose nanofibers by lactic acid mediated catalysis

Scientific Reports, 2023
Celulose nanofibers are lightweight, recycable, biodegradable, and renewable. Hence, there is a great interest of using them instead of fossil-based components in new materials and biocomposites.

Extraction model of low methoxyl pectin from apple pomace effects of acid concentration and time on the process and the product

Brazilian Archives of Biology and Technology, 2009
In Brazil, one of the top apple producing countries in the world, apple processing is an increasing activity, with pomace as the main by-product. To extract pectin from pomace, factors affecting process and product should be studied for optimization.

Transformation of hard pollen into soft matter

Nature Communications, 2020
Pollen is an abundant material; but, currently has limited applications. Here, the authors turn pollen grains into soft microgel by de-esterification of pectin molecules and explore the mechanical and structural changes of the pollen grains using ...

The Ectopic Expression of a Pectin Methyl Esterase Inhibitor Increases Pectin Methyl Esterification and Limits Fungal Diseases in Wheat

Molecular Plant-Microbe Interactions, 2011
Cell wall pectin methyl esterification can influence plant resistance because highly methyl-esterified pectin can be less susceptible to the hydrolysis by pectic enzymes such as fungal endopolygalacturonases (PG). Pectin is secreted into the cell wall in

De-esterification of cephalosporin para-nitrobenzyl esters by microbial enzymes.

The Journal of Antibiotics, 1976
Bacteria and actinomycetes were screened for esterase enzymes capable of removing the para-nitrobenzyl ester from cephalosporins. An esterase preparation from Bacillus subtilis was used to prepare cephalexin and 7-ADCA from the corresponding para-nitrobenzyl esters.
