Amino Acids Flashcards
1
Q
What is an amino acid?
A
-monomers of polypeptides
2
Q
What do amino acids do?
A
-cell growth, repair + structure
-form enzymes, membranes + hormones
3
Q
Structure of amino acids
A
-same amine group - NH2
-same carboxylic acid group - COOH
-R groups differ - resulting in different properties
4
Q
What bonds form between amino acids?
A
-covalent bonds
5
Q
How do amino acids form bonds?
A
-OH is lost form carboxylic group
-H is lost from amine group of the other amino acid
-condensation reaction = water produced
6
Q
What are dipeptides?
A
-condensation of 2 amino acids
7
Q
What are polypeptides?
A
-condensation of 3 amino acids
8
Q
How do you break peptide bonds?
A
-hydrolysis - beaks it back into amino acids
