Nucleic Acids
It depends on why you mean by "fat" molecules. Lipids in general are usually composed of carbon, hydrogen, and oxygen but they can contain other elements such as phosphorous or nitrogen.
Hydrogen bonds occur between polar molecules when hydrogen is linked to nitrogen, phosphorous or fluorine.
DNA comes to mind.
Nitrogen is composed of molecules each containing two nitrogen atoms
Air is composed of non-metals (Nitrogen, Oxygen, Carbon Dioxide, Hydrogen, assorted Noble Gasses), as is water (H2O), and the majority of living matter (Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorous)
No, it does not contain gold. Hemoglobin is an organic polymer and globular protein consisting of carbon, hydrogen, nitrogen, oxygen, and sulfur with an iron core. When discussing molecules that are organic, they are typically composed of some combination of the elements sulfur, phosphorous, oxygen, nitrogen, carbon, and hydrogen. In college chem, we always learned to remember this with the word "SPONCH".
Molecules can be composed of hydrogen atoms along with other elements such as oxygen, carbon, nitrogen, and more. Water (H2O) is an example of a molecule made up of hydrogen along with oxygen.
Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorous!
No. Lactose is a sugar containing only carbon, hydrogen, and oxygen.
No, it is a molecules composed of a nitrogen atom bonded to three hydrogen atoms.
No, hydrogen chloride is not considered an organic molecule. It is a simple inorganic compound composed of hydrogen and chlorine atoms. Organic molecules are generally composed of carbon atoms bonded to hydrogen and possibly other elements like oxygen, nitrogen, or sulfur.
Yes, and Hydrogen too.
