The macrophage eats short chain proteins?

They are an alteration of the white cell, but seem to be quite happy with a variety of short chain protein strands. It is about error counts, not quantities.   SHortmchains in the environment are not fixing nitrogen  efficiently, debris, so the macrophage are the shortened shortened fractional sets from the original.  They put out the rawest of sewage.

So, we really have some collection of antibody that eat four chain proteins, macrophage, then there is the five chain eater, and likely one more the seven chain.  At any given time, the  arrangement of these will all operate with the same closest match to proteins available. Likely a small number, 35? But that is error updates, not full amounts, it need only count this accuracy to the current environment. But the immunologist knows that with that accuracy, it is possible to count out the most dastardly and leave alone the least, if he could measure with that accuracy.
