Food molecules are primarily broken down into macronutrients: carbohydrates, proteins, and fats. Carbohydrates are broken down into simple sugars like glucose, proteins into amino acids, and fats into fatty acids and glycerol. This breakdown occurs through enzymatic processes in the digestive system, allowing these smaller molecules to be absorbed into the bloodstream through the intestinal walls for use by the body. Additionally, vitamins and minerals are absorbed in their original forms, contributing to overall nutrition.
I think chemical digestion
The breakdown of large food molecules into their basic building blocks by enzymes is called digestion. This process allows nutrients to be absorbed and used by the body for various functions.

Digestion is the breakdown of large food molecules into small, water-soluble food molecules that can be absorbed.
The process of food entering the bloodstream is called absorption. Enzymes that are released by various organs of the digestive system assist in the chemical breakdown of food into smaller molecules so that it can be absorbed by the body.
Enzymes are the molecules responsible for catalyzing biochemical reactions, including the breakdown of food molecules. They act as biological catalysts by lowering the activation energy required for these reactions to occur.
Assimilation of food nutrients in the human body refers to the process where the body absorbs and utilizes the nutrients from food for various physiological functions. It involves the breakdown of food into smaller molecules, absorption of these molecules in the intestines, and their transport to cells where they are used for energy production, growth, and repair. Nutrients such as carbohydrates, proteins, fats, vitamins, and minerals are assimilated to support overall health and well-being.
enzymes
The breakdown of food into molecules small enough to enter the bloodstream is primarily accomplished by the process of digestion. This involves mechanical and chemical breakdown of food in the mouth, stomach, and intestines, with the help of enzymes, to break down macromolecules into smaller molecules that can be absorbed by the body.
