Nothing is digested by the liver in the digestive system at all. So there is basically no answer to it.
The ileum is the end of the small intestine it basically absorbs digested material through its wall which enters into the bloodstream.
Starch is digested by ptyalin.
Protien
Saliva
It is starch! I think
The nutrient that is not digested but stimulates intestinal muscle contractions is fiber. Fiber is a type of carbohydrate that may be soluble or insoluble.
Starch (carbohydrates) is broken down (digested) to maltose by salivary amylase.
CelluloseAnswer:To be a nutrient a food material has to be digested and incorporated into the body as stored fat, converted to muscle or other protein, or converted to energy. So no nutrient as "not digested"/ Non-nutrient materials which provide other functions are fiber and water, and minerals asn trace chemicals such as salt, iron, zinc. Vitsmins can be regarded as supplimental to the body's own production. fibre can not be digested
fats
In the Small Intestine there are three section that are responsible for digestion and nutrient absorption. The first section is called the duodenum. The duodenum is manly responsible for the digestion of food. The second section is called the jejunum. The jejunum is the primary site of nutrient absorption. The third section is called the ileum. The ileum is the section that absorbs the nutrients that the jejunum missed.

the portion of the mammalian small intestine that follows the duodenum and precedes the ileum that is the function of absorbing digested food
