Properties of Proteins
Concept Questions
Question #1

One of the major discoveries made about the structure of proteins was the size of the intact molecule, and the way in which the components of the molecule interacted together to form complex three dimensional shapes in space. These shapes are very, very important to the ability of the protein to carry out its functioin.

In which of the links below do you find a description of the folding of the intact protein molecule so that any part of the constituent amino acids which are hydrophobic are located towards the interior of the macromolecule as it begins to function?

Link-#22 Link-#63 Link-#87 Link-#39

Question #2

Intact protein molecules are very large, and would not normally be soluble in water. However, the shape of the macromolecule is such that R-groups from certain amino acids extend out, into the surrounding water, and interact strongly.

In which of the links below is the role that hydrophilic forces play in determining protein shape described?

Link-#79 Link-#17 Link-#14 Link-#46

Question #3

Often the weakest forces play the most important roles in determining the three dimensional shape of a protein molecule. The hydrogen bond is a very weak, but very important force.

In which of the links below is the hydrogen bond discussed and its role examined?

Link-#88 Link-#21 Link-#03 Link-#54

Question #4

The final shape of a protein often includes a series of 'domains' of secondary structure.

In which of the following links is there a description of these domains and how they come together?

Link-#92 Link-#71 Link-#72 Link-#93
