D)List the name of two amino acids that belong to each of these type of amino acids: Nonpolar (hydrophobic) polar(uncharged) positively charged (basic) negatively charged (acidic)
- a. A tetrapeptide is abbreviated as PSQE. Write the name of the amino acid at the N-terminal end. b. A tetrapeptide is abbreviated as FRWL. Write the name of the amino acid at the C-terminal end.The mutated form of hemoglobin (hemoglobin S, or HbS) in sickle-cell anemia results from the replacement of a glutamate residue by a valine residue at position 6 in the B chain of the protein. Normal hemoglobin is designated HbA.What does it mean for an amino acid to be polar? Please explain what qualities about an amino acid might make the amino acid polar. The disease known as sickle cell anemia is due to a genetic mutation which replaces glutamic acid, a polar amino acid with valine. Please explain how this affects the hemoglobin.
