Hasil dari pemotongan enzim ini antara lain maltosa, maltotriosa, dan glukosa. Enzim bekerja dengan cara bereaksi dengan molekul substrat untuk menghasilkan senyawa turunan melalui suatu reaksi kimia organik yang membutuhkan energi aktivasi lebih rendah, sehingga percepatan reaksi kimia terjadi karena reaksi kimia dengan energi aktivasi lebih tinggi membutuhkan waktu lebih lama.

While amylases are found naturally in yeast cells, it takes time for the yeast to produce enough of these enzymes to break down significant quantities of starch in the bread. Despite the obvious benefits, early humans did not possess salivary amylase, a trend that is also seen in evolutionary relatives of the human, such as chimpanzees and bonobos eenzim, who possess either one or no copies of the gene responsible for producing salivary amylase.

In addition the same event occurred enaim in rodents, emphasizing the importance of salivary amylase in organisms that consume relatively large amounts of starch.

Such is the case for some Asian populations that have been shown to possess few AMY1 copies relative to some agricultural population in Asia. Alfa-amilase akan memotong ikatan glikosidik -1,4 pada molekul amilum karbohidrat sehingga terbentuk molekulmolekul karbohidrat yang lebih pendek. Five to 10 times the ULN may indicate ileus or duodenal disease or renal failure, and lower elevations mailase commonly found in salivary gland disease.

Pelepasan produk menyebabkan sisi aktif enzim bebas untuk berikatan dengan substrat lainnya. Pemanasan yang dilakukan bertujuan agar enzim pada percobaan berada dalam suhu optimum.

Different temperatures optimize the activity of alpha or beta amylase, resulting in different mixtures of fermentable and unfermentable sugars.

Yeast then feeds on these simple sugars and converts it into the waste products of alcohol and CO 2. The test for amylase is easier to perform than that for lipasemaking it the primary test used to detect and monitor pancreatitis.
