2. (3 pts.) The anthocyanin that is extracted from the red cabbage is in the neutral, purple colored form, A. When acid is added it becomes the protonated oxonium ion form, AH+. The reaction is shown below for A reacting with the hydronium ion, H3O+. For the reaction shown below, indicate the Lewis acid and base (LA/LB) and whether they are also Bronsted acids/bases (BA/BB), and, add the curved-arrow pushing showing bond making and breaking. Note, this is trickier than it looks, to generate AH+ in the form shown below you will need to draw a total of 6 curved arrows, and, the electrons that form the bond to the proton on the hydronium are not the non-bonding ones!
Also, indicate which bonds are being made and which bonds are being broken!

Although we normally think of acetic acid as an acid, it can also act as a weak base. Treated with a strong acid, it can become protonated. The conjugate acid of acetic acid is shown below н Нзс- Нзс- H -н Derive a resonance structure for this ion which, taken with the given structure, would show that the two -OH groups are equivalent, the two C-O bonds are equivalent, and the positive charge is shared equally by the two oxygens....

strands that interact with each other. Considering just a single
strand within a sheet, the Ser and Ala side chains will be

on one side; in the next repeat on the other side) (the answer
depends on whether the strands are parallel or antiparallel) (on
the same side of the sheet).

The equations for organic reactions usually focus on the desired transformation from reactant to product, other possible products such as byproducts and/or side products are often not included, even though it is understood that these are also formed in almost every organic reaction.
