How is starch transformed in human body?

It is first decomposed into maltose by salivary amylase, and then maltose is decomposed into glucose. Glucose is glycolytic to produce pyruvate, pyruvate; Or starch is directly decomposed into glycolytic intermediate glucose-1-P (this part has not been fully mixed with saliva). Then pyruvate is produced.

Pyruvate combines with enzyme to produce acetyl coenzyme A, and then enters citric acid cycle. Citric acid, sir. For every glucose consumed in the citric acid cycle, six NADH and two FADH2 are produced. (electronic carrier). Then in the mitochondrial membrane structure, these electrons produce a lot of ATP and energy through ATPase.
