What's the difference between endecane and undecane?
Endecane
Definition:
(n.) One of the higher hydrocarbons of the paraffin series, C11H24, found as a constituent of petroleum.
Example Sentences:
Undecane
Definition:
(n.) A liquid hydrocarbon, C11H24, of the methane series, found in petroleum; -- so called from its containing eleven carbon atoms in the molecule.

(7) The unsubstituted hydrocarbons were straight-chain (n-hexane through n-undecane) and branch-chain (eight carbons).
(8) Cells grown on n-tridecane or n-tetradecane yielded small amounts of acids homologous to the carbon source, but a similar correlation was not noted for n-decane, n-undecane, or n-dodecane.
(9) Non-proteinogenous aminobutyric acids were found in the pool of the cells grown on all tested media with an exception of the medium containing undecane.
(10) The pharmacokinetic and pharmacodynamic properties of the spiro carboxylic acid, spiro[4.6]undecane-2-carboxylic acid (SUCA, ADD 93024), were investigated in rats and compared with those of the standard anticonvulsant carboxylic acid, valproate (VPA).
(11) The adsorbed amounts decreased approximately in the order: propanal, biacetyl, hexenal, hexanal, acetone, pentan-3-one, nonan-3-one, undecanal and nonan-5-one, but there were great differences in the adsorption capacity of the amino acids.
(12) Histrionicotoxin is (2pR, 6S, 7pS, 8aS)-7-(cis-1-buten-3-ynyl)-8-hydroxy-2-(cis-2-penten-4- ynyl)-1-azaspiro[5.5] undecane, while in dihydro-isohistrionicotoxin the acetylenic 2-pentenynyl side chain is replaced by an allenic 2-(3,4 pentadienyl) substituent.
(13) The maximum effect within the first 10 min of the exposure period decreased from heptane to undecane, equivalent to a decrease in intrinsic activity.
