Can someone explain the levels of protein structure to me? (9th grade honors biology student)
Im so confused. especially around the secondary structure.
heres what I know:
Primary - One polypeptide, the kind of amino acids in chain and how they’re arranged
secondary - two polypeptides and how they interact (I don’t understand the alpha helix and folds in the chain)
tertiary - two polypeptides folding
quaternary - 2+ tertiary structures folding together to make a functioning protein.
I don’t really know how to explain what I don’t know. I think I just don’t understand the difference between 2+3
