[Glycerin supply and procurement] Glycerin has been present in our bodies for countless thousands of years

Glycerin (also known as glycerol) is colorless, odorless and tasteless Sweet, an organic substance that appears as a clear, viscous liquid. It is miscible with water, alcohols, amines and phenols in any proportion, and the aqueous solution is neutral. Glycerin is a polyol moisturizer. The hydroxyl groups in the molecular structure can form hydrogen bonds with water molecules, which plays a good role in absorbing and locking water. Glycerin has a wide range of uses. Currently, it has more than 1,700 uses. It is used in both food and industry. Glycerol can generally be divided into four grades: industrial grade, cosmetic grade, food grade, and pharmaceutical grade. In fact, our body also contains glycerol. Let’s take a look at the supply of glycerol:

Glycerin that exists in the human body:

The hydrolysis reaction of fats , is also ongoing in our bodies, but what catalyzes this reaction is mainly lipase secreted by the pancreas. The fats and oils in the food we ingest have been ground by the stomach and dispersed by bile. In the duodenum, the fats and oils have been dispersed into small oil droplets. Catalyzed by lipase, they are hydrolyzed into fatty acids and glycerin. These fatty acids and glycerol are absorbed into the bloodstream in the small intestine and enter our bodies. Therefore, glycerol is not toxic to us humans, and we can absorb glycerol directly. Glycerol has existed in our bodies for countless thousands of years, but we just don’t know it.

Of course, it is not just oils that contain glycerol in living organisms. As we all know, the basic unit of living organisms is the cell, and the basic scaffold that constitutes the cell membrane is a bilayer with phospholipids as the main component. Most of the phospholipids that make up the cell membrane are glycerophospholipids. The so-called glycerophospholipids also use glycerol as the skeleton and are connected with different fatty acids and phosphates. These glycerophospholipids ingested as food are also hydrolyzed into glycerol, fatty acids and phosphoric acid in our small intestine and absorbed into our bodies.

What is the use of glycerin that we absorb? The most important uses are to re-synthesize fat with appropriate fatty acids, and to re-synthesize glycerophospholipids with appropriate fatty acids and phosphoric acid. The fatty acids here may be ingested or synthesized by the body itself. The fat re-synthesized in this way is our own body fat, and the synthesized glycerophospholipid is our own glycerophospholipid, which forms the cell membrane of our own cells.

In this way, no matter what kind of plants or animals we eat, no matter where the fat is on them, no matter where the cell membranes are, they are all turned into glycerol, fatty acids, and phosphoric acid in our gastrointestinal tract. These small chemical parts. These parts are absorbed into the body and reassembled in our own way into our own fat, our own cell membranes. You will never grow pig fat by eating pig fat or beef by eating beef.

Of course, some glycerol will participate in other biochemical processes in our body. For example, it can be synthesized into glucose through a more complex process, or it can be directly oxidized to release heat, etc. In short, glycerin is a chemical that plays an important role in our bodies.
