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?

What is the significance of HEPES buffer in maintaining the pH stability of PK reactions?
HEPES buffer is important in maintaining the pH stability of PK reactions because it helps to resist changes in pH caused by the production or consumption of protons during the reaction. This stability is crucial for the proper functioning of the enzyme pyruvate kinase (PK) and ensures that the reaction proceeds efficiently.
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 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.
