So for this question, we're going to determine whether these statements are explaining or describing the primary, secondary, tertiary, or quaternary structure.
00:12
So briefly, the primary structure is just the amino acids lined up in a linear chain or the only interaction is this peptide bond here.
00:25
And then secondary, we have two forms.
00:29
So we have the alpha helix, which is made from these hydrogen bonds within one chain, and it's just the backbone of the peptide interacting.
00:43
And then same with this beta sheet.
00:48
It's the backbone, the interaction between them, and it's just hydrogen bonds.
00:54
Then we have tertiary, which is interactions between residues.
01:02
Of a peptide.
01:05
So you can have distant amino acids interacting because of their functional groups and forming bonds and causing this folding interactions.
01:17
So you'll see some i drew beta sheet here and the alpha helix here.
01:22
So you'll see those structures within the tertiary.
01:24
And then coronary structure is the interactions between different chains or different peptides.
01:35
So i have these pink, yellow, and this, for example, is four different chains interacting together...
