In terms of which molecules are hydrolyzable, that means they need to be able to react with water in a way that breaks them apart in some fashion.
00:18
Wax is hydrocarbon.
00:21
It consists only of carbons and hydrogens, saturated hydrocarbon.
00:28
And saturated hydrocarbons are unreactive with water, certainly in a hydrolysis sense.
00:36
So we can eliminate choice one.
00:42
Now, fatty acids are the products of hydrolysis of fatty acid esters.
00:49
So the ester is hydrolyzable, but the fatty acid itself has already formed from hydrolysis.
01:01
So it will not undergo additional hydrolysis.
01:05
So we're left with sucrose and protein, but there is no option that has choices two and four only.
01:19
Now, we know proteins are hydrolyzable.
01:22
The peptide bonds are amides, and they can be hydrolyzed to get the constituent amino acids.
01:30
And that is how the identity of the amino acids can be determined.
01:36
It doesn't identify the sequence, but it identifies the amino acids.
01:42
So we know four has to be true...
