because oxygen was not present in the early earth.
Carbon is always present in all organic compounds, but lacking in inorganic compounds. Similarly hydrogen is always present in organic compounds but are missing in inorganic compounds.
Carbon and hydrogen are found in all organic compounds. Oxygen and nitrogen are also commonly present in organic molecules.
Organic compounds comprise more of the body than inorganic compounds. Organic compounds, such as carbohydrates, lipids, proteins, and nucleic acids, are essential for the structure and function of cells and tissues. Inorganic compounds, such as salts and minerals, play important roles in various bodily processes but are present in smaller quantities compared to organic compounds.
aliphatic, alicyclic, aromatic and heterocyclic compounds.
Carbon. That is why organic chemistry is often called carbon chemistry.
Carbon is present in all organic compounds.
Carbon is always present in all organic compounds, but lacking in inorganic compounds. Similarly hydrogen is always present in organic compounds but are missing in inorganic compounds.
Carbon is the element present in every organic compound. Organic compounds are defined as compounds that contain carbon-hydrogen bonds.
lipids
No, all organic compounds contain carbon and hydrogen. Hydrogen is an essential element in organic chemistry and is always present in organic compounds.
Carbon is the basic element.
Carbon is fundamental to all organic compounds. Organic compounds contain one or more C-H or C-C bonds. All organic compounds contain carbon, but not all carbon-containing compounds are organic, such as carbon dioxide.Carbon is the foundation for making organic compounds. Every organic contains carbon. Hydrogen is also present in every organic compound.
Carbon and hydrogen are found in all organic compounds. Oxygen and nitrogen are also commonly present in organic molecules.
Carbon
Yes, sulfur, hydrogen, and plutonium can be found in organic compounds. Sulfur is commonly found in amino acids, such as cysteine and methionine. Hydrogen is present in virtually all organic compounds, as it forms covalent bonds with carbon. Plutonium can be incorporated into organic compounds through synthetic processes in laboratories, but naturally occurring organic compounds with plutonium are rare.
Although Carbon is present in all organic compounds, carbon dioxide is not considered to be an organic compound. Nor are carbonates.
Carbon and hydrogen are the elements present in every organic compound. Additionally, organic compounds can also contain oxygen, nitrogen, sulfur, and other elements.
