Answer
Starch molecules are not absorbed into the blood from the digestive system because they are complex carbohydrates that need to be broken down into simpler molecules first by digestive enzymes.
Explanation
Starch is a complex carbohydrate that the body cannot readily absorb in its whole form. In order for it to be absorbed into the blood from the digestive system, it first needs to be broken down into simpler sugars or molecules. This process, known as digestion, is facilitated by enzymes in the body.
