Most organic compounds contain carbon and hydrogen, but they may also include any number of other elements (e.g., nitrogen, oxygen, halogens, phosphorus, silicon, sulfur). Originally limited to the ...

Virtually all organic material on Earth ... process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis ...

The function of many biologically active molecules ... transfer to organic molecules. Rather, the majority of biosynthetic carbon-nitrogen bonds are generated downstream of carbon-oxygen bonds ...

He had studied and taught organic chemistry before that, with a specialization in polymers, molecules composed ... or more repeating units of carbon, hydrogen, and oxygen atoms, strung in a ...

Researchers have discovered a new method by which a catalyst can be used to selectively burn one molecule in a mixture of hydrocarbons -- compounds made of hydrogen and carbon atoms.

These compounds of carbon and nitrogen use light to break water into its constituent parts, oxygen and hydrogen—with hydrogen representing a promising renewable energy source. But how exactly does ...

However, Ph.D. Candidates Emma Cook and Anna Davis, along with Associate Professors of Chemistry Charles Machan and Michael Hilinski, discovered an organic molecule made of carbon, hydrogen ...

Students use Snap Cubes to make models of atoms and molecules. They are given white, red, blue, and black cubes that represent hydrogen, oxygen, nitrogen, and carbon atoms respectively. Students are ...
