Introduction to Nutrition Elements-Inorganic Nutrition

We know that there are six essential nutrients for people’s lives: water, inorganic salts, vitamins, carbohydrates, fat and protein. The first three are inorganic nutrients, and the last three are organic nutrients.

As a college student who majors in bio-chemistry, today, let me introduce the first three inorganic nutrients for you. So let’s start.

Water is the source of life. In any biochemical reaction, water acts as a catalyst and solvent. Water provides a place for chemical reactions. And it also increases the reaction rate extremely. What is more importantly, water and human metabolic reactions are closely related. It is the famous TCA Cycle that is carried out in the human body fluid environment. Nutrition can be dissolved in water and transported to the whole body with blood. It can be said if there is no water, then there is no life. There is nothing important than water.

Also it has been found that inorganic salts have a great relationship with hormone synthesis and some special protein synthesis in human body. For example, human hemoglobin contains negative ferrous elements (creative proteomics provides excellent bioinformatics analysis ). Human bones and teeth are rich in calcium. And the substances that control human neurons, synapses that release neurotransmitters, are sodium and potassium salts. Lack of these two inorganic salts can lead to symptoms of muscle weakness. Dangerous words can even lose the ability to breathe. In addition to metal salts, other non-metallic salts are also very important. N, P and S are necessary for the composition of human genetic material DNA. Lack of these three elements is fatal to human beings.

In addition to the above two accidents, vitamins are also very important nutrients and vitamins are divided into two kinds, Water Soluble Vitamin and Fat Soluble Vitamin. There is a difference between the two. Water-soluble vitamins are soluble in water but not in non-polar organic solvents. They need not be digested. After being absorbed directly from the intestine, they are circulated to the tissues needed by the body. Most of the excess vitamins are excreted by urine and stored very little in the body. Water soluble vitamins are easily soluble in non-polar organic solvents, but not in water. They are absorbed in the small intestine through bile emulsification and enter the various organs of the body from the lymphatic circulation system. A large number of fat-soluble vitamins can be stored in the body. Lack of vitamins can have many effects on the human body. For example, vitamin C deficiency can lead to scurvy. Lack of vitamin D may lead to calcium deficiency. And the most effective way to supplement vitamins is to eat more vegetables and fruits, balanced nutrition. Children can get more sunshine. Sunlight can promote the production of vitamin D in children, which is very helpful for children’s growth.
