Answer:
The concentration of protons affects an enzyme's folded structure and reactivity.
Explanation:
Enzymes act within narrow pH limits (optimal reaction pH). Since most enzymes have a protein structure, the variation in pH or temperature affects their enzymatic activity.
To catalyze a reaction, an enzyme binds to one or more reagent molecules. These molecules are the substrates of the enzyme.
In some reactions, a substrate breaks into several products. In others, two substrates join together to create a larger molecule or to exchange parts. In fact, for any biological reaction that can occur to you, there is probably an enzyme to accelerate it.
The part of the enzyme where the substrate binds is called the active site.
The amino acid residues of the active site often have acidic or basic properties that are important for catalysis. Changes in pH can affect these residues and make binding with the substrate difficult.
Answer:
Protons 4 or 5 are most acidic.
Explanation:
As mentioned there are four types of hydrogen in Hexane-2,4-dione.
The numbering are shown in the figure for your better understanding.
As shown in the figure if we remove the proton from carbon number 3 (protons number 4 or 5), it will result in formation of a carbanion. This carbanion is stabilized due to presence of -I group oxygen and there is possibility of resonance (as shown).
Thus protons 4 or 5 are most acidic.
A super acid is defined as an acid with acidity greater than 100% pure H2SO4. It can also be defined as a medium in which the chemical potential of the proton is higher than in pure Sulphuric Acid.
