Chondroitin sulfate contains a sulfate group (pka 1.99) and a carboxyl group (pka ~4.7) (as highlighted in pink). if i placed chondroitin sulfate in a solution at ph 1, which scenarios will occur: select one: a. the sulfate and carboxyl group would get protonated and increase hydrogen bonding within itself, thereby decreasing in volume b. nothing would happen c. the sulfate and carboxyl group would not get protonated and increase electrostatic repulsion, thereby increasing the volume of space chondroitin takes up. d. the carboxyl group, but not the sulfate group would be protonated causing attraction of the two groups to each other and the formation of a helix type structure. e. none of the above
