N-number: A protein has a molecular mass of 400 kDa when measured by size-exclusion dodecyl sulfate (SDS), the protein gives three bands with molecular masses of 180, chromatography. When subjected to gel electrophoresis in the presence of sodium 160, and 60 kDa. When electrophoresis is carried out in the presence of SDS and the reducing agent, dithiothreitol (DTT), three bands again form, this time with molecular masses of 160, 90, and 60 kDa. How many subunits does the protein have, and what is the molecular mass of each?

Scientists can learn a great deal about a community's drug use (both legal and illegal) by analyzing the contaminants in wastewater. In a recent study in New York State, chemists measured the concentration of cotinine, a derivative of nicotine that i produced in the liver and excreted in the urine of tobacco users. The chemists found the average cotinine concentrations in the wastewater stream was 1.43 µg/L. a Ι Ι H- b HH H H-C C-N: C=0: TH HH Jonutis/Shutterstock Revell, Introductory Chemistry, 2e, © 2021 W.
