Question

Saponification of a triacylglycerol:

I need help setting this reaction up. I started to create it, but I don't think i fully understand what the question is asking.

Answer 1

The "hint" to the problem says " Saponification reactions involve base-mediated hydrolysis of ester linkages between the three fatty acyl chain and the glycerol backbone. Each hydrolysis reaction will produce one free fatty acid, i.e. -O-CO-R, plus one alcohol group on the glycerol backbone. Complete hydrolysis will result in glycerol plus three fatty acids. The carboxylic acids will be negatively charged at a neutral pH."

Answer 2

This is what I came up with, but it was incorrect

Answer 3

the question says do not include Na+

Answer 4

@caozeyuan.... so just leave out NaOH and just have OH for a reactant..... and don't have Na+ as a product?

Answer 5

in reactant you have the triglycerol and OH-. in product you have fatty acid (in COO- form) and the glycerol

Answer 6

@caozeyuan do I draw the fatty acid in 3 different windows like I originally did?

Answer 7

I think so, if thats not right just try again

Answer 8

Thank you!
