Question

Item 33 

Which pair of side chains could be involved in a hydrophobic interaction? Check all that apply. 

Item 35 

Cold cereal is often fortified with all sorts of vitamins and minerals but is deficient in the amino acid lysine. How might this deficiency be compensated for? Check all that apply 

Item 36 

The following statement describes what level of structure in a protein? 

The set of linked amino acids folds repeatedly and creates a large linear globular shape. 

quaternary structure 

tertiary structure 

secondary structure 

primary structure 

none of the above 

Answer 1

Hydrophobic interactions take place when there are no partially or completely charged ions or functional groups like acid and amine. Therefore options 1 & 2 are correct.

Fruit, beans, milk and vegetables have a rich amount of lysine in it. Hence options 2,4,5,6 can be used.

The globular protein arrangement is simply the 3-D dimensional structure of a protein where the protein forms globules or spheres. This kind of structure is seen in RBC. It is the Tertiary Structure of protein.
