Explain the effect of saliva on starch?
  • 1 answers

Yogita Ingle 7 years, 5 months ago

Saliva is the first digestive juice secreted in our mouth by the salivary gland. It has an enzyme called salivary amylase that breaks down starch,a complex molecule,to sugar. So when saliva is added to starch it breaks it down into sugar and when we drop iodine solution to this mixture it will not turn blue black indicating that starch is broken into sugar. But if the solution turns blue black then it means that the starch has not completely broken into sugar. This is the effect of saliva on starch.
