His attempts to isolate a glycolytic ferment from flesh were also only partially successful.
We do not know at present if any corresponding anti-toxin or antitrypsin, as we may term it, is returned into the lymphatics or blood from the gland, but the pancreas, which in addition to secreting trypsin secretes a diastatic ferment forming sugar from starch, pours this into the intestine and secretes at the same time a glycolytic ferment which breaks up sugar, and this latter passes into the blood by way of the lymphatics.
These individuals typically have a large majority of "fast twitch" muscle fibers that have a highly developed glycolytic energy system.
