- Q:How the most primitive life on earth is produced under what conditions
- These macromolecules are not in the modern sense of the protein and nucleic acid polymer, but a variety of amino acids, nucleosides, phosphoric acid, carbohydrates and some other small molecules of the disorder of the polymer, when the nucleoside and phosphoric acid composition of nucleoside Acid, and gradually form a nucleotide chain, the formation of these nucleotide chain of the amino acid on the formation of the field of binding force, and then assembled peptide chain. Or by the combination of a variety of amino acids into peptide chain formed by the force field on the surrounding nucleus formation field binding effect, and then assembled the nucleotide chain, with the formation of peptide chain and nucleotide chain longer and longer , The molecular weight is growing, and ultimately the formation of nucleic acids and proteins, nucleic acid and protein formation is the product of interaction with each other, is generated at the same time.
- Q:Simply talk about hydrocarbons
- Hydrocarbon products in the daily production, life is widely used, the most representative of the commercial life of the HCR433b hydrocarbon refrigerant, and the most representative of the automotive HCR436a hydrocarbon refrigerant.
- Q:From the molecular level, are not all the energy obtained from the redox reaction?
- You find the block out of the lithium battery thrown into the fire try ........ look at how the energy density
- Q:Why does the molecular atom compound do not belong to the life structure
- Life structure is composed of CHO as the main element through the covalent bond of the combination of hydrocarbons and their derivatives, and you said the molecular atomic compounds are usually atomic or ionic bond
- Q:Carbon compounds (except inorganic carbon compounds), hydrocarbons and derivatives of the general term is?
- Organic matter
- Q:Are all carbon compounds all organic?
- Not ah, like CO, CO2, carbonated, carbonate is not ah
- Q:What is organic matter?
- Organic matter usually refers to carbon-containing compounds, or hydrocarbons and their derivatives are collectively referred to as organic compounds.
- Q:What is the definition of organic matter
- Organic matter usually refers to carbon-containing compounds, or hydrocarbons and their derivatives are collectively referred to as organic compounds.
- Q:What is a derivative of a hydrocarbon? What is an aromatic hydrocarbon derivative?
- Hydrocarbon derivatives include derivatives of linear and aromatic hydrocarbons such as chloroethane bromopropane bromobenzene
- Q:Why is dry ice not organic?
- Inorganic compounds are pure metals that do not contain carbon and a collection of simple carbon compounds such as carbon monoxide, carbon dioxide, carbonates, carbonates and carbides.
