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:
“The excessive increase of anything often causes a reaction in the opposite direction.”
—Plato (c. 427347 B.C.)
“In contrast to revenge, which is the natural, automatic reaction to transgression and which, because of the irreversibility of the action process can be expected and even calculated, the act of forgiving can never be predicted; it is the only reaction that acts in an unexpected way and thus retains, though being a reaction, something of the original character of action.”
—Hannah Arendt (19061975)
“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)
