Peptides and polyamides Flashcards
1
Q
What happens when amino acids undergo acid-base reactions under acidic conditions?
A
N gains a H+
2
Q
What happens when amino acids undergo acid-base reactions under alkaline conditions?
A
COO- ions is formed and NH2 gains a H+
3
Q
How is a peptide bond formed?
A
between C of carboxylic acid and N of NH2, lost 1 molecule of water
4
Q
How can you make polyamides?
A
From a carboxylic acid and amine but this requires catalyst and industrial conditions
5
Q
What is a better way to make polyamides?
A
Using acyl chloride
6
Q
What is the equation for making an amide with acyl chloride?
A
Acyl chloride + 2NH3 -> Amide + Ammonium chloride
