For What Mechanistic Reason Does G1 of Lactase First Act as a Brønsted Acid During Catalysis??

In the AAMC prep, passage 7 question 53 asks essentially what would happen if a lactose molecule were to be hydrolyzed based on passage information. The passage shows us an image of a compound turning into a beta D-galactose molecule.

Good passage notes and mapping make this type of question easier (and practice helps). In addition, question 54 asks “For what mechanistic reason does G1 of lactase first act as a Brnsted acid during catalysis“.

For what mechanistic reason does G1 of lactase first act as a brønsted acid during catalysis A?

For what mechanistic reason does G1 of lactase first act as a Brønsted acid during catalysis? G1 becomes a better nucleophile. G2 becomes a better nucleophile. Glucose becomes a better leaving group.

How does the lactase enzyme work?

How does Lactase work? Lactase is a transmembrane protein located in the lipid bilayer membrane such that its active sites extend into the lumen of the intestine. When the enzyme lactase binds to the disaccharide lactose, its active sites cleave lactose into its two constituent sugars: glucose and galactose.

Which statement about the interaction between Dnmt3a and the DNA substrates is supported by the data in Figure 1?

The question asks ” Which statement about the interactions between Dnmt3a and the DNA substrates is suported by the data in figure 1? the answer was that the stability of the protein/ DNA fibers formed on the 509mer Dna strand was greater than those formed on the 30mer DNA strand.

What was the experimentally determined value of KNAG from the study described in the passage?

45) What was the experimentally determined value of KNAG from the study described in the passage? The passage told us that we could find the value of Knag from the slope. So, taking it back to seventh grade algebra we take slope is Δy/Δx = (2 – 1)/(0.020 – 0.00) = 1/0.020 = 50.

Glu-2 performs nucleophilic attack onto lactose, and it remains attached to galactose in the subsequent step involving the intermediate. It’s just like how in a classic SN2 reaction (not saying this one is SN2), the LG is the part of the molecule that does not end up containing the attacking nucleophile. In this case, D-glucose is freed without attachment to the nucleophilic Glu-2 so it is the LG.
