Unlike land plants, which mostly contribute cellulose and lignin, marine life is rich in lipids and proteins. These hydrocarbons exist in various forms, ranging from simple gases like methane to complex, heavy molecules.
The Molecular Building Blocks: From Ancient Organisms to Hydrocarbons
Aromatics: Stable ring structures that, while less prevalent, are highly reactive and valuable for chemical manufacturing. When these organisms died, they sank to the seafloor and became buried under layers of sediment.
The Molecular Composition: Hydrocarbons and More Chemically speaking, what is made out of oil is primarily hydrocarbons—molecules consisting entirely of hydrogen and carbon atoms. Paraffins: Straight-chain molecules that are usually the most abundant, determining the oil's volatility and energy content.
The Molecular Composition of Crude Oil: Hydrocarbons and Organic Matter from Ancient Marine Life
Oil also contains trace amounts of metals such as nickel, vanadium, and iron, which originate from the rocks surrounding the organic-rich source material. Biological Origins: The Organic Matter The primary ingredient in oil is organic matter, specifically the fossilized remains of tiny marine organisms such as algae and zooplankton.
