Ethyl: the ethyl group, CH3CH2−, is bonded to a hydroxyl group to form ethanol (ethyl alcohol), CH3CH2OH. The reaction of ethanol with urea creates ethyl carbamate, which can occur naturally in fermented foods and alcoholic beverages (bread, soy sauce, yoghurt, beer, fruit brandies) when...
We first rebuilt the ligand in the active site by adding a sulfate group to the hydroxyl group of tyrosine. The simulation revealed that four active site residues (Y37, L71, W129, and D182; Supplementary Fig. 1a) engaged in unfavorable interactions with the new ligand. These four residues...

In addition, silane-based [56,57], pyrrole-based [58,59], and p-aminothiophenol [60,61] were used owing to their benefits and different functionalities. In general, a monomer consists of two kinds of units, the recognition unit such as the vinyl group and the polymerizable unit such as ...
LAB initiate rapid and adequate acidification in the raw materials, through the production of various organic acids from carbohydrates. Lactic acid is the most abundant, followed by acetic acid, whilst LAB can also produce ethanol, bacteriocins, aroma compounds, exopolysaccharides and some enzymes [...
Two sample preparation methods were employed in this work. For imaging the surface morphology of microgels, critical point drying (CPD) was used: first, carrier oil was removed, and photo-cured samples were directly resuspended in 50% ethanol. Microgels were gradually dehydrated consecutively by 75...
group in the purine base (purine → 2-AP) resulted in a slight enhancement in splicing efficiency (see Fig. 4, and compare adenine with purine and 2-AP; also, see below). However, a guanine base, unlike 2-AP, has a 6-keto and a N1-H group (Fig. 2), and it resulted in ...
Chemical halogenation is an important transformation in organic synthesis. Halogenations involve the use of reactive and toxic halogens (X2) or hydrogen halides (HX). Chemical halogenations are fast and exothermic, but with little regio- or stereoselecti
Between trials, the mouse was confined by a removable transparent acrylic cylinder (diameter = 6”) in the center of the arena. The arena was wiped with 70% ethanol between animals. The mouse was food restricted starting ~5 days before the testing day so that its body weight was ...
A genetic system, ProTracer, has been recently developed to record cell proliferation in vivo. However, the ProTracer is initiated by an infrequently used recombinase Dre, which limits its broad application for functional studies employing floxed gene al
