La amilasa pancreática es una endoglicosidasa que hidroliza enlaces alfa 1-4 de poliglícidos de glucosa
+
-
 
+
-
para entender porqué solamente ataca los enlaces interiores del poliglícido es necesario ver cómo se coloca el poliglícido al unirse al centro activo . 1cpu muestra la estructura de la amilasa pancreática . El <scene name='42/428167/Centro_activo/2'>centro activo </scene>se muestra ocupado por 5 unidades glicídicas que son abrazadas por la hendidura del centro activo . En rojo se muestran los dos aminoácidos principales que participan en la catálisis, aspártico 197 y glutámico 233.

-
En esta nueva visión vemos <scene name='42/428167/Detalle_centro_activo/1'>la relación entre los aminoácidos ácidos del centro activo y el pseudosubstrato (superfície de puntos)</scene> Vemos como los dos aminoácidos ácidos caen en el centro del glícido y atacan la parte central. Por tanto dado el "diseño" de este centro activo es imposible que pueda hidrolizar diglícidos con eficiencia

==Regulation==

α-Amylase is regulated through a number of inhibitors. These inhibitors are classified according to six categories, based on their tertiary structures<ref name="inhibit">PPMID: 17713601</ref>. Inhibitors of α-amylase block the active site of the enzyme. In animals, inhibitors control the conversion of starch to simple sugars during glucose peaks after a meal so that breakdown of glucose occurs at a rate the body can handle<ref name="inhibit"/>. This is particularly important for diabetics, who require low quantities of α-amylase to maintain control over glucose levels. After taking insulin however, pancreatic α-amylase escalates. Plants use these inhibitors as a defense mechanism to inhibit the use of α-amylase in insects, thus protecting themselves from herbivory<ref>PMID: 11856298 </ref>.
