α-淀(dian)(dian)粉(fen)酶以鏈淀(dian)(dian)粉(fen)為底物時，反應(ying)一般按兩階(jie)段進行。首先，鏈淀(dian)(dian)粉(fen)快速(su)地降解，產(chan)生(sheng)(sheng)低(di)聚(ju)糖(tang)(tang)(tang)(tang)，此(ci)階(jie)段鏈淀(dian)(dian)粉(fen)的(de)黏(nian)度及(ji)與碘發生(sheng)(sheng)呈(cheng)色反應(ying)的(de)能力迅速(su)下降。第二階(jie)段的(de)反應(ying)比階(jie)段慢很多，包括低(di)聚(ju)糖(tang)(tang)(tang)(tang)緩(huan)慢水解生(sheng)(sheng)成終(zhong)產(chan)物葡(pu)萄糖(tang)(tang)(tang)(tang)和麥芽糖(tang)(tang)(tang)(tang)。α-淀(dian)(dian)粉(fen)酶作用于支淀(dian)(dian)粉(fen)時產(chan)生(sheng)(sheng)葡(pu)萄糖(tang)(tang)(tang)(tang)、麥芽糖(tang)(tang)(tang)(tang)和一系列限(xian)制糊精(由4個或更多個葡(pu)萄糖(tang)(tang)(tang)(tang)基(ji)構成低(di)聚(ju)糖(tang)(tang)(tang)(tang))，后者(zhe)都含有α-1，6-糖(tang)(tang)(tang)(tang)苷鍵。
