'The protein-folding problem' box at the beginning of this chapter discussed how scientists are trying to predict the final shapes of proteins from a knowledge of their primary structures. What information about amino acids and proteins would be relevant to feed into a computer program trying to make such predictions? 

Try making models of or drawing these molecules:

methane, CH₄

Try making models of or drawing these molecules:

water, H₂0

Try making models of or drawing these molecules:

a hydrocarbon, e.g. C₃H₈

Try making models of or drawing these molecules:

ammonia, NH₃

Try making models of or drawing these molecules:

 ethanoic acid, CH₃COOH

Copy the table and complete both the columns. The table shows some functions of proteins, with examples of proteins that carry out these functions.
