And actually, this is the reverse pathway that we discussed in the previous lecture. So previously we discussed how we can break down alanine into ammonium, but now we see how, under other conditions, we can actually do the reverse. We can take the ammonium combined with Pyruvate to ultimately form that alanine, and it's the alanine that is transported out of the cell into our bloodstream and that ultimately is absorbed by hepaticides, our liver cells. Now, once the alanine moves into the liver, the alanine basically undergoes this pathway. But in reverse. So we begin with Alanine.
