How do the levels of structure achieved in proteins?

Need both questions answered

Protein Structure and Folding:a. Explain how changes in a protein’s amino acid sequence can change the way it behaves in water.b. Explain how changes in a protein’s amino acid sequence can change the way it interacts with othermolecules.c. Explain how changes in a protein’s amino acid sequence can change the way it forms secondary andtertiary structures when placed in water.

can you help me with this question? the list at the bottom is for part a.

Part C - Classifying molecules by their functional groups Functional groups confer specific chemical properties to the molecules of which they are a part. In this activity, you will identify which compounds exhibit certain chemical properties as well as examples of those six different compounds. Drag one molecule and one chemical property to each bin. If one property can apply to more than one functional group, choose the best answer for each functional group. ▸ View Available Hint(s) forms HHO disulfide H-C C-C-O-H HHO H-C-C-C-H acts as a base bonds A A H A contributes negative charge HH H -S-H HH HH A alcohol carboxylic acid aldehyde 0 C-0- P-0- thiol is polar and makes compounds HHH | | | may H-C-C-C-H structura more soluble HNH of a k in water H H acts as an acid amine

1.Describe in detail how to detect the primary structure of protein. 2.Given a mixture of lysine,histidine and cysteine.The isoelectronic point of the amino acids are as follows: histidine:7.64 lysine:9.74 cysteine:5.02 Show how you will separate the mixture into the pure forms. State and describe any instrument that you will use to separate the components in the mixture.

Answer the following multiple choice questions, and pick from the following a, b, c, d

1.Describe in detail how to determine the primary structure of protein. 2.You have been given a mixture of lysine, histidine and cysteine.The isoelectric point of the amino acids are as follows; histidine 7.64 lysine:9.74 cysteine:5.02 Show how you will separate the mixture into the pure forms. State and describe any instrument that you will use to separate the components in the mixture.

How does knowledges of protein structure help us to predict the function of unknown proteins?
