Complex answer: Cellulose is a polysaccharide that provides structural support for plants. Humans cannot digest cellulose. Thus, you cannot digest wood, which is mostly cellulose.
:Simple answer Humans cannot digest the carbohydrate cellulose.

Fiber
Celulose. Some humans also cannot digest lactose aka someone who is lactose intolerant.
Humans can digest starch because they produce an enzyme called amylase that can break down starch into simpler sugars. However, humans lack the enzyme needed to break down cellulose, which is a complex carbohydrate found in plant cell walls. This is why humans cannot digest cellulose.
Fibre is a carbohydrate that the body cannot break down. It is very important for functionality of the digestive system and to control glucose absorption and other functions that we are learning about. Fibre is in a form of soluble and insolubles. Both are needed and beneficial to our bodies
Yes, humans can digest starch. Starch is a complex carbohydrate that is broken down by enzymes in the digestive system into simpler sugars that can be absorbed by the body for energy.
It is Cellulose
No. Tissues are made of paper which is made from cellulose which humans cannot digest.
As dogs will primarily eat and digest meat, animal protein is far more important than carbohydrates. A dog does not need a great deal of carbohydrate, and cannot digest certain carbohydrates as efficiently as protein.
One common complex carbohydrate made up of plants is cellulose. Cellulose is a structural component of cell walls in plants and provides rigidity and support to the plant structure. It is a type of fiber that humans cannot digest but is important for digestive health.
glucose
Humans can't digest roughage (eg. cellulose) because of the beta linkages that hold the glucose molecules together. Humans don't have enzymes that can break these linkages.
No, humans cannot ingest any counties, Irish or not.
