Inorganic compounds, compounds unrelated to the body (some compounds related to the body are also inorganic compounds, such as water), corresponding to organic compounds, usually refer to compounds that do not contain carbon elements, but include carbon oxides, carbonates, hydrides, etc., abbreviated as inorganic compounds.
Inorganic compounds, abbreviated as inorganic substances, refer to all elements and their compounds except for organic substances (substances containing carbon frameworks), such as water and air. Salt, sulfuric acid, carbon monoxide, carbon dioxide, carbonic acid, carbonates, hydrides, etc. are also inorganic substances. The vast majority of inorganic substances can be classified into four categories: oxides, acids, bases, and salts. The inorganic substances in living organisms mainly include water and some inorganic ions, such as Na+, K+, Ca2+, Mg2+, Cl -, SO42-, etc. See "Biological Elements" section. Medical | Education Network collects and organizes various elements that almost exist in nature in human tissues. Except for carbon, hydrogen, oxygen, and nitrogen, which mainly exist in the form of organic compounds, the rest are collectively referred to as inorganic substances (minerals or ash). So, inorganic substances are mainly composed of water and inorganic salts, among which water can be classified as bound water and free water. bound water is an important component of cell structure, and free water is a good solvent for transporting substances and participating in chemical reactions. Inorganic salts can be divided into ions and compounds. Ions are essential components for maintaining normal cellular life, while compounds are important components of intracellular compounds.
