Is the dimerization favored at this temperature ? Thermodynamically speaking, explain/support your answer. Show work.Give advantages of Ziegler–Natta catalysts ?What is known as Ziegler–Natta catalysts ?
- Asparagine and glutamine residues in proteins are deamidated in an aqueous solution to yield aspartate and glutamate, respectively, and ammonium. Proteins undergoing deamidation of one or more of their Asn or Gln groups have been detected by isoelectric focusing. Why would isoelectric focusing be effective in separating deamidated from non-deamidated protein? Compare the relative pI values of the deamidated and non-deamidated proteins.Give a clear handwritten answer??asapwhy are these sterically hindered what does it even mean to be stericaly hindered

- The catalytic efficiency of many enzymes depends on pH. Chymotrypsin, which has a well-known catalytic mechanism, shows a maximum value of kcat/Km at pH 8.0. A) Draw a pH curve of chymotrypsin activity over the pH range of 5 to 10 and briefly explain the rationale within the context of catalysis for your depiction. In particular, note how kcat and Km may change over this pH range. B) Enzymes of the a-amylase family catalyze a reaction by forming a covalent intermediate analogous to chymotrypsin, but to a conserved aspartate residue. Illustrate a catalytic mechanism containing a tetrahedral intermediate for a glycogen debranching enzyme based upon its potential membership in the a-amylase family.
