When starch enters the mouth, it is acted upon by salivary amylase which is an enzyme that breaks starch down into maltose. It is not fully digested yet.

In the stomach, low PH levels caused by the hydrochloric acid denatures the salivary amylase, rendering it useless for starch digestion. The starch remains in the stomach, until it's churning action turns starch into chyme (liquefied food) The purpose of this is to increase the surface area to volume ratio, so as to increase the efficiency of enzyme action.

The starch leaves the stomach, and enters the small intestine. In the intestine, it is acted upon by the intestinal amylase, and the pancreatic amylase, which fully breaks down the starch into maltose. Afterwhich, the maltose is acted upon by maltase, which breaks it down into glucose. When this is done, it can be absorbed easily by the villi into the bloodstream.

Glucose is formed. Then to simpler form called maltose. Next it becomes sucrose, galactose, and fructose. I think...

True or false digestion beings in your stomach?

False. Digestion (at least starch digestion) begins in your mouth. Saliva helps begin the break-down process as you chew. Chewing is also a means of the start of the breakdown process of food going into your GI tract.
