Given this information what’s the compound? What would be the route to get to the base ion peak?
Mass spectrometry and X‑ray diffraction are common biochemical techniques for characterizing proteins. Classify each statement based on whether it applies to mass spectrometry, X‑ray diffraction, or both techniques.
Based on the chromatograms, Symmetry C18 (top) is less selective than Symmetry Shield RP18 (bottom) for the analytes given, true or false?
True or false and why is false 8 Structures produced by X-ray diffraction are as good as the solutions from which they are derived 9 Hard keratins (such as in the skin) are less resistant to stretch because the larger number of disulfide bonds resist deformative forces. 10 The vast majority of structures deposited in the Protein Databank (>95%) have been determined using NMR
Colorimetric reagents. Proteins will intensely absorb 280 nm light even in the absence of a colorimetric reagent (See figure). Why is it advantageous to use the Bradford reagent to measure protein concentration rather than just measuring protein absorbance (280 nm) directly?
Which structure does this IR belong to and why?
Five uL of a 10 to 1 dilution of a sample were added to 5 mL of Bradford reagent. The absorbance at 595 nm was 0.78 and, according to a standard curve, corresponds to 0.015 mg of protein on the x axis. What is the protein concentration of the original solution? Why?
CHM 102 3. The figure below shows a Beer's Law plot for the absorbance of 5 different known solutions of crystal violet along with the equation for the linear regression line (trend line). a.

What does cross peak X tell you?
True or false and why is false 1 There are 2 major classes of keratins: alpha keratins (found in mammals) and beta keratins (found in feathers and scales of birds and reptiles) 2 One estimate of mobility within a crystal is the B-factor that reflects spreading or blurring of electron density 3 In NMR, the longitudinal relaxation time (T1) reflects the rate at which magnetization returns to the longitudinal axis after a pulse
