Major kinds of inorganic molecules inside cells:

• Water. perhaps most important and most abundant. molecule in the body.
• Electrolytes (ions) molecules that tend to disperse in solution into. charged atoms.
• Gasses.
• carbohydrates.
• lipids.
• proteins.
• nucleic acids (include ATP)
• vitamins. most larger organic molecules are polymers of.

The three elements that make up over 99 percent of organic molecules are carbon, hydrogen and oxygen. These three combine together to form almost all chemical structures needed for life, including carbohydrates, lipids and proteins.

While organic molecules can have non-carbon atoms contained inside them, like oxygen, nitrogen, or even iron, they are mostly made of carbon and hydrogen chains. Because of this, they are made almost entirely of covalent bonds. Inorganic molecules do not contain carbon-hydrogen bonds.

In general, there are four groups of inorganic compound types. They are divided into bases, acids, salts, and water. Note that these are the broadest categories of inorganic compounds.

Carbon compounds such as carbides (e.g., silicon carbide [SiC2]), some carbonates (e.g., calcium carbonate [CaCO3]), some cyanides (e.g., sodium cyanide [NaCN]), graphite, carbon dioxide, and carbon monoxide are classified as inorganic. …

Four elements, hydrogen, carbon, oxygen and nitrogen, are the major components of most organic compounds.

noun, plural: inorganic molecules. (1) A molecule not consisting of carbon atoms. (2) Any molecule that is not considered organic, or not of biological origin. Supplement. Inorganic molecules are not usually found in living things but abound in nature or Earth.

Molecules other than organic molecules (see also organic molecule). Inorganic molecules are generally simple and are not normally found in living things. Although all organic substances contain carbon, some substances containing carbon, such as diamonds, are considered inorganic.

Inorganic compounds essential to human functioning include water, salts, acids, and bases. These compounds are inorganic; that is, they do not contain both hydrogen and carbon.

Some simple compounds that contain carbon are often considered inorganic. Examples include carbon monoxide, carbon dioxide, carbides, and the following salts of inorganic cations: carbonates, cyanides, cyanates, and thiocyanates.

Water
Water, which is the most important inorganic molecule for life has a very peculiar behaviour when it becomes solid. Ice floats on top of liquid water as a result of its hexagonal packing within its crystalline structure.

Many inorganic compounds are ionic compounds, consisting of cations and anions joined by ionic bonding.

But the basic inorganic chemical principles are the same. Transition metals, almost uniquely, react with small molecules such as CO, H 2, O 2, and C 2 H 4. The industrial significance of these feedstocks drives the active area of catalysis. Ligands can also undergo ligand transfer reactions such as transmetalation .

An inorganic compound is a substance that does not contain both carbon and hydrogen. A great many inorganic compounds do contain hydrogen atoms, such as water (H 2 O) and the hydrochloric acid (HCl) produced by your stomach. In contrast, only a handful of inorganic compounds contain carbon atoms.

„Organic molecules: Larger, more complex molecules whose structure is based on a backbone of C atoms (always contain C as a major part of their structure). Examples: C6H12O6, C2H5COOH „Living organisms are composed of
