A TLC plate showed two spots with Rf values of 0.25 and 0.26. The plate was removed from the developing chamber, the residual solvent was allowed to evaporate from the plate, and then the plate was returned to the developing chamber. What would you expect to see after the second development was complete?

What is an amino acid? How many amino acids are there?

When 2-propanol was used as the develop- ing solvent, two substances moved with the solvent front (Rf = 1) during TLC analysis on a silica gel plate.

1. When 2-propanol was used as the develop- ing solvent, two substances moved with the solvent front (Rf = 1) during TLC analysis on a silica gel plate. Can you conclude that they are identical? If not, what additional experiment(s) would you perform? 2.The Rf value of compound A is 0.34 when a TLC plate is developed in hexane and 0.44 when the plate is developed in diethyl ether. Compound B has an Rf value of 0.42 in hexane...

A mutation replaces the original amino acid, leucine, with threonine in a large protein. The altered protein still functions, but less efficiently. What amino acid might replace leucine but with less effect on protein functions? What amino acid might replace leucine but with even a worse effect on the how the protein functions? a) less effect if lysine; worse if alanine b) less effect if methionine; worse if lysine c) less effect if methionine; worse if alanine d) less effect...

“Protein A” is phosphorylated at one amino acid by a kinase, “protein B”, and dephosphorylated by a phosphatase, “protein C”. You have purified all three of these proteins and want to determine the structural changes that occur when protein A is phosphorylated or dephosphorylated. Explain in detail how you would go about designing and conducting this investigation.
