A molecule must contain this exact arrangement to be a steroid, though most also have side chains— additional atoms that can dramatically impact the molecule's function.

And each of those amino acids are going to have a different side chain which is going to be if we look at everyone of these amino acids, the top part is identical.

And so if we change the pH of the overall protein, so this is the myoglobin, for example, it's going to change the behavior of each of those side chains and the amino acid inside it.

因此， 果我们改变整个蛋白质的 pH 值，例肌红蛋白，它将改变每个链和其中氨基酸的行为。
