I'm going as this question again as it seems to far down the list to be answered now. Sorry if this is considered spam.
Wow, look how smart I am! I didn't even ask the question.
We are learning about proteins and their structure, but one thing is confusing me.
At what structural point is something considered a protein? Is a protein formed after two amino acids synthesis, or is a protein the whole structure (all four levels) put together?
I would think you would need all four structural levels to form a protein, but my teacher refers to the first structure as a protein molecule.
