Another fossil-fuel gas used in cooking appliances is "propane", used commonly in backyard grills and RV/camping stoves. Propane is a bigger hydrocarbon: 3 carbons single-bonded in a chain, and the remaining bonds are taken by hydrogen. Its formula is C3H8 and its structure is shown below. KEY POINT: the products are the same as the combustion of methane, but more is produced. The graphic below shows that one propane molecule reacts with 5 oxygen molecules to form molecules of carbon dioxide. C3Hg + 502 → 3CO,+ 4H,0 00O OOO SOLDICKATEr LTELNOO II RLIARaRr H
Nucleotides
It is an organic molecule made up of three basic components- a nitrogenous base, phosphate,and pentose sugar. The nucleotides are important for metabolic reactions andthe formation of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).
Nucleic Acids
Nucleic acids are essential biomolecules present in prokaryotic and eukaryotic cells and viruses. They carry the genetic information for the synthesis of proteins and cellular replication. The nucleic acids are of two types: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The structure of all proteins and ultimately every biomolecule and cellular component is a product of information encoded in the sequence of nucleic acids. Parts of a DNA molecule containing the information needed to synthesize a protein or an RNA are genes. Nucleic acids can store and transmit genetic information from one generation to the next, fundamental to any life form.
