A new method of tracking the dietary habits and contaminant exposure of animals in Arctic marine ecosystems is providing ...

Animals, plants and many other living organisms inhale oxygen to "burn" (oxidize) compounds like sugar into CO2 and water—a process during which the energy-rich molecule ATP is produced. Cells require ...

Linolenic and linoleic fatty acids contain long carbon chains of 18 carbons each, but other fatty acids of similar size, such as steric acid and oleic acid, cannot replace them. These "essential ...

(A) This is the structure of stearic acid, an 18-carbon saturated fatty acid. The normal numbering system, starting with the carboxylic acid, is shown in blue. The carbons and oxygens of the ...

Carbon is found in organic matter (carbon-based compounds associated with living things), from complex proteins down to amino acids, chemicals so simple they're called the "building blocks" of life.

Researchers in Sweden report a green alternative to reduce reliance on mining graphite, the raw source behind the "wonder ...

Carbon dioxide reacts with water to produce carbonic acid. The double arrow means that carbonic acid breaks down pretty readily to form carbon dioxide and water again. A hydrogen atom from the ...

In its solid state, carbon dioxide is commonly called dry ice. CO2 is an acidic oxide: an aqueous solution turns litmus from blue to pink. It is the anhydride of carbonic acid, an acid which is ...

“We are taking a biologically sustainable source of carbon and hydrogen, and we are turning that into renewable hydrogen and renewable acetic acid. That’s quite neat.” The team says the ...
