Biological molecules need to be digested to break them down into smaller, absorbable units that the body can utilize for energy, growth, and repair. Complex macromolecules like proteins, carbohydrates, and fats must be hydrolyzed into amino acids, simple sugars, and fatty acids, respectively. This process also allows for the removal of waste products and the efficient absorption of nutrients through the digestive system. Ultimately, digestion is essential for maintaining cellular function and overall health.
it makes the molecules smaller and simpler
Proteins are obtained from nutrients of food. They starts to digest in stomach by proteases such as pepsin, trypsin in to peptides. These small peptides later digested further to form amino acids after complete digestion.

The large intestines, or colons to be specific, transport digested food molecules into the blood stream
Protein is digested to form amino acids. Lipids are digested to fatty acids. Carbohydrates are digested to glucose and other simple sugars.

No. Being digested would mean the body falling apart into basically molecules. And that is not survivable.

The carbohydrate molecule is often referred to as the backbone of biological molecules as it is essential for storing and providing energy. However, carbohydrates are often not represented in diagrams of biological molecules for simplification purposes.
