The Lewis base are anionic in nature. The base strength of Lewis base is dependent upon the $p{K_a}$ of the parent acid. The reaction between Lewis acid and Lewis base is shown below. ${A^ + } + {B^ - } \to A - B$ Where, ${A^ + }$ act as Lewis acid ${B^ - }$ ...
Identify the group, family, or other periodic table location of the element with the given outer electron configuration. ns2np3 Periodic Properties of Elements: The physical and chemical properties of every element that are abundant in nature will ...
At the stem basis of each plant a piece of 1 cm of each stem was cut and immediately frozen in liquid nitrogen. Stem pieces were ground in liquid nitrogen in an orbital ball mill for 2 min at a frequency of 30 Hz s−1(MM400 Retsch GmbH, Haan, Germany) with three balls of stainl...
We performed a bottom-up proteomics analysis of plasma, which had been depleted of the major blood proteins, using two-dimensional in-line liquid chromatography fractionation into ten fractions and label-free mass spectrometric analysis by QTOF MSE. The discovery cohort consisted of ten randomly selec...
For the carbonate ion, {eq}CO_{3}^{2-} {/eq}, draw all the resonance structures. Identify which orbitals overlap to create each bond. Orbital Overlapping: Orbital overlapping refers to the interaction of atomic orbitals from different atoms to form covalent ...
The length of a planet's apparition depends upon its orbital period (i.e. the time it takes the planet to orbit the Sun) and its position in relation to the Sun and the Earth at any given time. Apparitions can last from just a few weeks (in the case of Mercury) to almost two ...
Values shown are relative NAD2 copy number compared to the wild-type strain in the absence of DOX. Error bars represent SEM above and below the mean of technical triplicates (two-way ANOVA, Bonferroni correction for multiple comparisons, **P < 0.002; ***P < 0.0004; ****P <...
Tracking data from penguins (above) and crabeater seals (below) shows where they go to feed on krill. Credit: Dan Costa Marine Protected Areas (MPAs) are a crucial tool in the conservation management toolbox. Existing and proposed MPAs in the Southern Ocean are mostly found within the areas...

These results indicate that the enzyme is functioning at a similar velocity with the two substrates, which have similar Km values (see below). A linear correlation between the concentration of ENPP1 and product formation is shown in Figure 2B, demonstrating initial velocity conditions. Download: ...
