Which has lower pk value - 2-bromopentanoic acid or 3-bromopentanoic acid and why?
3-bromopentanoic acid would have a lower pKa value compared to 2-bromopentanoic acid. This is because the bromine atom in 3-bromopentanoic acid is closer to the carboxylic acid group, making it more acidic due to increased stability of the resulting carboxylate anion through resonance stabilization.
What is the pk values of phosphoric acid?
The pKa values of phosphoric acid are 2.15, 7.20, and 12.35. These values correspond to the three dissociation steps of phosphoric acid, where each hydrogen ion is progressively released to form H2PO4-, HPO4^2-, and PO4^3- ions.
Is Chalk powder an acid or a base?
Chalk powder, also known as calcium carbonate, is not an acid or a base. It is a salt compound that is considered to be pH neutral.
What Abbreviations for enzymes involved with the breakdown of glucose?
Some abbreviations for enzymes involved in the breakdown of glucose are HK (hexokinase), GK (glucokinase), PFK (phosphofructokinase), PK (pyruvate kinase), and G6Pase (glucose-6-phosphatase).
What is the titration curve of phenylalanine?
The titration curve of phenylalanine shows the pH changes as a strong acid or base is added to a solution of phenylalanine. At low pH, the carboxyl group is protonated and the amino group is deprotonated. As the pH increases, the carboxyl group loses a proton first, followed by the amino group. The curve typically shows two distinct equivalence points corresponding to the two acidic pKa values of phenylalanine.
What type of net charge do most proteins carbohydrates and nucleic acids have?
Most proteins have a net charge at a specific pH due to the presence of different amino acid residues with varying pK values. Carbohydrates and nucleic acids are typically uncharged or have a neutral net charge due to their composition of sugars and phosphate groups.
How to calculate net charge of a peptide?
To calculate the net charge of a peptide, you need to consider the charges on its constituent amino acids. Each amino acid has a specific charge due to its side chain at different pH values. Add up the charges of all the amino acids in the peptide and take into account any N- and C-terminal charges to calculate the overall net charge of the peptide.
