Being one of the key enzymes in the pathway of starch biosynthesis, starch synthase is important contents of starch researches which often focus on the research of its isoforms. 摘要澱粉合酶作為澱粉合成的關鍵酶之一，一直是澱粉研究的重要內容。
Starch synthase includes two major kinds of isoforms, granule-bound starch synthase and soluble starch synthase, whose physiological functions are very complicated. 這些研究多集中在對其同工型的研究，澱粉合酶的兩類主要同工型分別為澱粉粒結合的澱粉合酶和可溶性澱粉合酶，這兩類同工型的作用極為複雜。
