Chemistry

(ETD) based fragmentation to detect ubiquitination sites in proteins. Our results indicate that ETD can provide alternative fragmentation patterns that allow detection of glY modified lysyl side chains, in particular z+1 fragment ions derived from triply charged precursor ions. We subsequently applied ETD fragmentation-based analysis and detected novel ubiquitination sites on DNA polymerase B1 that were not easily observed using CID. We conclude that ETD can provide significant alternative fragmentation information that complements CID-derived data to improve the coverage when mapping ubiquitination sites in proteins.

Consider the reaction and its equilibrium constant at 25.0 ∘C :
olga55 [171]

Since Qp>Kp , the reaction is not at equilibrium.

<h3>What is the equilibrium constant?</h3>

The equilibrium constant shows the extent to which reactants are converted into products.

Now we have to obtain the Qp as follows;

Qp =[CH3OH]/[CO] [H2]^2

Qp = 0.265/(0.265) (0.265)^2

Qp = 14.2

Now we know that Kp = 6.09×10−3, Since Qp>Kp , the reaction is not at equilibrium.

Use the equation 2cu+o2=2cuo to find how many miles of copper react to form 3.64 mil cuo
Firlakuza [10]
<h3><u>Answer;</u></h3>

3.64 moles

<h3><u>Explanation;</u></h3>

From the equation;

2Cu + O2 → 2CuO

Mole ratio of Cu : CuO = 2: 2 equivalent to 1: 1

Moles of CuO = 3.64 Moles

Therefore;

moles of Cu will be ;

3.64 × 1 = 3.64 moles

Moles of Cu = <u>3.64 moles </u>
