base hydrolysis of amides mechanism
How does base hydrolysis work?
And from there, we learned that basic hydrolysis is when water acts as an acid to break apart a weak base.
For example, water can react with urea, forming a hydroxide anion, which can then release ammonia from the urea, which is critical for the growth of plants.Key Takeaway.
The hydrolysis of an amide produces a carboxylic acid and ammonia or an amine.
What is the mechanism of the amide reaction?
The mechanisms starts with the nucleophilic acyl substitution by water while breaking the amide C-N bond.
This produces a protein fragment with an amine and another with a carboxylic acid.
The amine fragment will deprotonate the carboxylic acid forming the carboxylate and ammonium fragments.24 sept. 2022
