How do you find the minimum molecular weight of a protein when given info about their residues? Protein of interest put is Resin and it is put through gel filtration. 8g of the protein are obtained and it is found to have 2 residues: isoleucine and glutamate. If analysis shows 0.124mg of isoleucine and 0.209mg of glutamate, what is Resins minimum molecular weight?

5. A native protein has a molecular weight of 150,000 Da. Denaturing SDS electrophoresis results in two bands with molecular weights of approximately 53,000 and 23,000 Da. What arrangement of polypeptide chains in the native protein would best explain these results? 2. If two proteins have the same molecular weight, are they necessarily the same protein? Can you definitely assign the identity of a protein based on its molecular weight? Why or why not?

2. Myoglobin (Mb) is one of the most thoroughly studied and best understood proteins. It serves as a model for ligand binding by proteins. Mb is an example of a hemoprotein (a heme containing protein or heme protein) and its ligand is molecular oxygen (O2) which is essential for the survival of aerobic organisms. a. How does an organism benefit from having a protein bind O2? b. Where, specifically, does the ligand bind in Mb? c. Is the heme bound...
