Please help me right now! I will give you full credit if you answered it correctly. I am confused actually.
1. Starting with d-talose (you can find this in the book or online) draw the \(\beta\) -anomer of its pyranose Haworth structure.
a. How many stereocenters are in its Haworth structure?
b. How do you make the anomeric carbon unreactive?
