full_question: These compounds are reacted with o-phthaldialdehyde before quantification via HPLC which performs a similar function to CBQCA. A complex formed from molybdate and pyrogallol red can be used to detect these compounds. A method for quantifying these compounds is the most common use for a reagent originally meant for quantifying phenolic compounds such as gallic acid. Many assays for the concentration of these compounds rely on their behaving similarly to bi·uret, in which they complex with copper ions and the absorbance of the complex is measured. Coommassie blue stains these compounds in a test named for Bradford. BGG and BSA serve as common standards when measuring these compounds. A simple method of measuring the concentration of these compounds relies on their UV 280 absorptions when they contain aromatic side chains. For 10 points, name these biomolecules which are detected in a western blot.
