Sugar, protein, and fat have long been viewed as the three main nutrients, for they are deemed important as bioenergy sources and biogenic materials. The inner side of the small intestine is corrugated, bristled with innumerable villi protruding toward the lumen. Although enzymes that hydrolyze proteins are named generically as proteases, the structures of substrates to be most easily severed and their optimum conditions differ depending on each enzyme.
After being decomposed by proteases into amino acids or peptides consisting of several amino acids linked together, proteins enter the blood vessels via the epithelial cells of the microvilli protruding from the small intestine.
Blood that contains nutrients absorbed from the stomach and intestine converges at the portal vein and is conveyed to the liver. We consume genes of various animals, plants, and microorganisms in huge quantity in the form of food every day.

Sugar is also called carbohydrate, including monosaccharides, oligosaccharides, and polysaccharides, as well as glycoconjugates. The surface of the villi is covered with single-layer epithelial cells, and peripheral lymphatic vessels called capillaries and lacteal vessels run inside the villi. The portal veins are blood vessels located in the region between 2 capillary systems and transport nutrients and toxins absorbed from the intestines and stomach to the liver. Their decomposition into amino acids progresses in the cellular membranes or epithelial cells as well. These proteases are first biosynthesized in the cells and secreted into the lumen of the digestive tracts as inactive precursor proteins called pepsinogen, trypsinogen, and chymotrypsinogen, which include superfluous parts of proteases.


The surface area of the epithelial cells is enormous on account of their brush-like structure referred to as microvillus.
Pancreatic juice, which is produced in the pancreas and secreted from duodenum, is weak alkaline and neutralizes gastric acid, thus keeping the inside of the small intestine neutral. The blood, after being treated in the liver, returns to the heart via the hepatic veins and is pumped into the whole body from there. For instance, ethanol is detoxified in the hepatic cells by oxidation to acetaldehyde and further to acetic acid, which is ultimately reduced to carbon dioxide and water after being circulated and decomposed in tissues throughout the body. It is not before these parts are cut off by already-active proteases in the lumen that these enzymes form active steric structures. Since the pancreas secretes nuclease (enzymes to hydrolyze RNA) and deoxyribonuclease (enzymes to hydrolyze DNA), and the small intestine secretes other nucleolytic enzymes, almost all nucleic acids present in the food are decomposed into bases or sugar phosphates before being absorbed into the blood vessels via epithelial cells.
Amylases produced in and secreted from the salivary glands and the pancreas eventually hydrolyze starch into oligosaccharides such as maltose. Nutrients absorbed from here pass through the epithelial cells and are transported to the portal vein via the capillaries or to the lymphatic vessels via the lacteal vessels. Pancreatic juice contains various digestive enzymes functioning under neutral conditions, for example, amylases and proteases including trypsin and chymotrypsin, lipases that hydrolyze lipids, and nucleolytic enzymes. 8-1), meanwhile, are absorbed into the epithelial cells along with other fatty acids after partial hydrolyzation by lipases.
In addition to the portal vein, the hepatic artery branching from the aorta also flows into the liver. The cells therefore can synthesize and secrete a copious amount of proteases without being digested until then. Although some base moieties are reutilized, other bases are discharged as uric acid in the case of humans, which sometimes causes gout due to crystallization owing to its low solubility.


These oligosaccharides are decomposed further into glucose by small intestinal enzymes and absorbed from microvilli in the small intestine. The duodenum also receives the bile, which is secreted in the liver and temporarily stored in the gallbladder before being released. In the epithelial cells, they are resynthesized into neutral lipids, which form complexes with proteins there (referred to as chylomicrons) and then enter the lymphatic vessels.
After being filtrated in the liver, the blood exits the liver via the hepatic vein and is pumped into the whole body from the heart (Fig. Besides, mucus is secreted profusely from the surface of the gastric wall, serving as a barrier to protect the wall from gastric acid and pepsin. Bile contains surfactants that assist digestion through emulsification and dispersion of lipids in food. Besides, in order for genes to function, DNA macromolecules with genetic information need to be absorbed intact into cells and integrate into their chromosomes. Moreover, such a phenomenon must occur in reproductive cells if the offspring are to inherit the genetic information. Hydrolyzation of starch involves various types of enzymes, such as ones that break the middle of glucose chains, ones that snip off branches, and ones that cut the chains from their termini. Considering this, it is unlikely that food-derived DNA is passed down to future generations among humans; factually, no trace for such a phenomenon has been discovered in the human genome.
