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. 摘要淀粉合酶作为淀粉合成的关键酶之一，一直是淀粉研究的重要内容。
Starch synthase includes two major kinds of isoforms, granule-bound starch synthase and soluble starch synthase, whose physiological functions are very complicated. 这些研究多集中在对其同工型的研究，淀粉合酶的两类主要同工型分别为淀粉粒结合的淀粉合酶和可溶性淀粉合酶，这两类同工型的作用极为复杂。
