Answer:
Fatty acids have an even number of carbons because they are synthesized from a starting material (acetyl-CoACoA) that has an even number of carbons.
Explanation:
Fatty acids are carboxylic acids and are known to have even number of carbon atoms because they are synthesized from a 2 carbon atom acetyl Co-A molecules which are assembled together. It contains a carboxylate group covalently joined with an hydrophobic head of CH3-(CH2)n and may have an unsatireated CH=CH group within its CH2 chain. The synthesis of fatty acids from acetyly Co-A involves the activation reaction of an enzyme acetyl Co-A synthetase with an acid. It involves dehydrogebation, hydration, oxidation and thiolysis. Fatty acids vary in length of its chain, the number of carbon-carbon double bonds attached to its CH2 chain nd also the location of those double bonds in the carbon chain. Saturated fatty acids are those without carbon-carbon double bond in its chain while unsaturated have carbon- carbon double bonds. Monounsaturated fatty acids have one carbon-carbon double bonds and polyunsaturated fatty acids have two or more carbon-carbon double bonds.
Question
Define chemical symbol and what is the significance of a chemical symbol. who first invented a chemical symbol.
Answer:
Chemical symbol - notation of one or two letters representing a chemical element.
J.J Berzelius - Swedish Scientist introduced chemical symbol in 1813.
The significant of chemical symbol is to have shorthand way to represent an element on the periodic table. it also used to standardized the language of chemistry and to identify elements and atoms in a chemical formula.
