1

what bond is formed between amino acids?

peptide

2

name 3 groups within proteins

AMINE GROUP (1 nitrogen, 2 hydrogen), CARBOXYL GROUP (1 carbon, 1 oxygen and 1 OH), R GROUP

3

what is the primary structure of proteins?

the sequence/chain of amino acids

4

what is the secondary structure of proteins?

atoms within the structure interact, hydrogen bonds may form pulling it into a alpha helices or the chain chan lie antiparallel in a beta plated sheet

5

what is the tertiary structure of proteins?

there are interactions within the R group forming hydrogen bonds, ionic bonds or disulphide bridges (closer together)

6

what is the quaternary structure of proteins?

2 or more subunit interacting

7

how are proteins identified?

using a biuret test (the peptide bonds form violet coloured complexes with copper ions in the alkaline solution

8

what is the monomer of proteins?

amino acids
