There are two major classes of Neuraminidase that cleave exo or endo poly-sialic acids:
- Exo hydrolysis of α-(2→3)-, α-(2→6)-, α-(2→8)-glycosidic linkages of terminal sialic acid residues
- Endo hydrolysis of (2→8)-α-sialosyl linkages in oligo- or poly(sialic) acids

Famous quotes containing the word reaction:
“In a land which is fully settled, most men must accept their local environment or try to change it by political means; only the exceptionally gifted or adventurous can leave to seek his fortune elsewhere. In America, on the other hand, to move on and make a fresh start somewhere else is still the normal reaction to dissatisfaction and failure.”
—W.H. (Wystan Hugh)
“Children, randomly at first, hit upon something sooner or later that is their mothers and/or fathers Achilles heel, a kind of behavior that especially upsets, offends, irritates or embarrasses them. One parent dislikes name-calling, another teasing...another bathroom jokes. For the parents, this behavior my have ties back to their childhood, many have been something not allowed, forbidden, and when it appears in the child, it causes high-voltage reaction in the parent.”
—Ellen Galinsky (20th century)
“The excessive increase of anything often causes a reaction in the opposite direction.”
—Plato (c. 427347 B.C.)
