Create a protin structure

Primary
Secondary
Tertiary
Quaternary 

Questions:
1. The type of bond that is found in the primary structure is polypeptide it`s
 a sequence of ameino acids with a minimum of 50 with a selection of 20 different acids . The peptide bonds are polar making one side negative and the other positive.

2.The secondary structure forms a alpha helix due to the polar  peptide bonds. the positive side is trying to attract to the negative side , forming a spiral shape. 

3. The tertiary  structure  is formed from the reaction of R groups , whether they be covaylant , hydorgin bonds or repulsion. It changed there shape making it look like a 3D structure 

4. The Quaternary structure is created when two or more polypeptides stick together through bonds creating a protein. 

5. The protein would be completely rearranged if the primary structure was to be altered with. For one , the amino acids would react to each other differently.  if in a sequence P and Y attracted and was changed to P and A and detracted from each other you would get a different  as well  other Polypeptides will stick together with other polypeptides which will make a different protein.

6.  and 

the amino acid structure has amino group ( left ) and a carboxylic acid (right). The Difference between their R groups is what makes them variant. Lucine is more coomple where serine has CH2 and OH.

  1. Well done - it looks like you understand protein structure.
