And we do it with every one of these beakers. And then we plot it on an x y axis, where the y axis is the absorption of light, and the x axis is the type of amino acid we actually use. And so what we see is the higher our value is, the higher this slope is, the higher our absorption is. And because in this protein, we have one alanine, one arginine, one phenylalanine, and one aspartate, the height of these values will be exactly the same. But because we had two glycine amino acids, what that means is this will be twice as high as any other one of these slopes. And so what that means is we have twice as many of the glycine.
