Structure of proteins

Question 1

what bond is formed between amino acids?

Answer 1

peptide

Question 2

name 3 groups within proteins

Answer 2

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

Question 3

what is the primary structure of proteins?

Answer 3

the sequence/chain of amino acids

Question 4

what is the secondary structure of proteins?

Answer 4

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

Question 5

what is the tertiary structure of proteins?

Answer 5

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

Question 6

what is the quaternary structure of proteins?

Answer 6

2 or more subunit interacting

Question 7

how are proteins identified?

Answer 7

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

Question 8

what is the monomer of proteins?

Answer 8

amino acids
