about the bond between the nitrogen and α-carbon atoms and the bond
between the α-carbon and the carbonyl carbon atom. These bond angles
define the conformation of the peptide chain.

- The α and ẞ subunits of hemoglobin bear a remarkable structural similarity to myoglobin. However, certain residues that are hydrophilic in myoglobin are hydrophobic in the subunits of hemoglobin. Why might this be the case? Hemoglobin forms long, extended structures that feature repeated sequences, whereas myoglobin forms globular structures. Hydrophobic residues on the surface of hemoglobin subunits interact with similar regions on the other subunits through van der Waals interactions. Hydrophilic residues on the surface of myoglobin form ionic interactions with similar regions on other myoglobin molecules. Myoglobin is a water-soluble protein, whereas hemoglobin is found in the hydrophobic environment of membranes.arrow_forwardProtein disulfide isomerase (PDI) is a protein folding enzyme that catalyzes disulfide-sulfhydryl exchange reactions. Ribonuclease is an enzyme with two ẞ-sheets, three α-helices, and four disulfide bridges critical to the stability of its structure. PDI rapidly converts inactive, scrambled ribonuclease to enzymatically active ribonuclease. This process is driven by the decrease in free energy as the scrambled conformations are converted into the stable, active conformation of the enzyme. In contrast, PDI rapidly inactivates insulin. What does PDI's effect on insulin imply about the structure of insulin? The three-dimensional shape of insulin does not contain any disulfide bonds. The active conformation of insulin has more ẞ-sheets than α-helices. The active conformation of insulin is not the most thermodynamically preferred form. The amino acid sequence of insulin is similar to the amino acid sequence of ribonuclease.arrow_forwardIn the 1950s, Christian Anfinsen demonstrated the renaturation of the protein ribonuclease (RNase) in vitro. After reduction and the addition of urea, the protein was in an unfolded state. After removing the urea and then the reducing agent, the protein oxidized and refolded, with greater than 90% activity. If reducing agent removal occurs before removing the urea, the protein showed less than 5% activity. Why does RNase refold incorrectly if the reducing agent is removed before urea removal? Contaminants in the RNase preparation would form covalent bonds with the protein, preventing reactivation. Urea would participate in weak bonding interactions with RNase, preventing oxidation of cysteine. Disulfide bonds are not positioned correctly unless weak bonding interactions are present. The protein would not fully denature.arrow_forward
- A hospital blood processing unit uses apheresis to concentrate red blood cells (RBCs) fromwhole blood donations. Whole blood is drawn from a donor at a rate of 100 g/min and passedthrough a centrifuge-based apheresis system. The whole blood contains 45% RBC and 1%WBCs and platelets by mass, with the remainder consisting of plasma. The separated plasma andnon-RBC components are returned to the donor at a rate of 90 g/min.The goal of the system is to collect a concentrated RBC fraction containing 80% red blood cells.Assume that red blood cells do not break down during processing and that no fluid loss occurs inthe system.(a) How long will it take to collect 100g of the concentrated RBC fraction?arrow_forwardPlease give an intuitive explanation of the blood-brain barrier.

The unfolding of the a helix of a polypeptide to a random conformation is accompanied by a large decrease in specific rotation. Polyglutamate, a polypeptide made up of only 1-Glu residues, has the a helix conformation at pH 3. When researchers raise the pH to 7, there is a large decrease in the specific rotation of the solution. Similarly, polylysine (1.-Lys residues) is an a helix at pH 10, but when researchers lower the pH to 7 the specific rotation also decreases, as shown in the graph. a Helix Specific rotation Poly(Glu) a Helix Random conformation Poly(Lys) Random conformation T + ° 2 4 6 В 10 12 14 PH Complete the statements about the molecular mechanism for these changes in specific rotation.
