Four levels of protein structure

Question 1

Primary

Answer 1

Sequence of amino acids in a polypeptide chains, influenced by dna
one gene = one polypeptide
Bond between amino acid is called a peptide bond

Question 2

Secondary

Answer 2

Shaoe that polypeptides chains form due to hydrogen bonding
Hydrogen bonds twist and polypeptide forming an alpha helix

Question 3

Teritarty

Answer 3

Alpha helix of a secondary futher twisted and foleded
Disuphic, ionic, covalent hyrophobic and hydrogen bonds
Enzymyms have a teritarty structure

Question 4

Quaternary

Answer 4

Two or more polypeptide chains
Haemaglobin
