Protein Structure and Function

Proteins have similar relationships between their structures and function to the structures and functions of our body parts.  Check out the questions before watching the video: we're only going to watch part of it!

Questions

Please answer the questions below.

Match the following proteins, non-protein analogs, and functions.

Note: Draw your sketch in the sketchpad below

Watch the video from 1:16-3:21. How can you remember the hierarchy of protein structure? (remember, the primary structure is just the sequence of amino acids…)

Amino acids can act differently from each other (they can be different sizes like the beads in the necklace have different hydrophobic and hydrophilic properties like phospholipids, oils, water, etc.). Based on this information, how do you think the primary structure could affect the other structures (secondary, tertiary, quaternary)?

 

SAQ: Eumelanin and pheomelanin (the pigments that make Maria and Lucy's hair different colors) are made by slightly different versions of the same protein.  Thinking back over the previous questions, why do you think slightly different versions of the same thing might do things differently?

Notes
