Substance chimique
An amino acid zwitterion obtained from γ-carboxy- L -glutamic acid by transfer of a proton from the α-carboxy group to the amino group.
A tricarboxylic acid dianion that is obtained from γ-carboxy- L -glutamic acid by removal of a proton from each of the carboxy groups and protonation of the amino group; the resulting entity has an overall charge of 2−.
An α-amino-acid residue anion obtained by removal of a proton from both of the γ-carboxy groups of γ-carboxy- L -glutamic acid residue.
A cyclic carotene obtained by the cyclisation of lycopene.
A sesquiterpene that is cyclohexa-1,3-diene which is substituted by a methyl group at position 1 and a 6-methylhept-5-en-2-yl group at position 4 (the R enantiomer).
A cycloamylose composed of eight α-(1→4) linked D -glucopyranose units.
A γ-lactone that is oxolan-2-one substituted by a hexyl group at position 5.
A γ-lactone that is oxolan-2-one substituted by an octyl group at position 5.
A sesquiterpene that is cyclohexane substituted at positions 1, 1, 2, and 4 by methyl, vinyl, isopropenyl and isopropylidene groups, respectively (the S , S stereoisomer).
A eudesmane sesquiterpenoid in which the eudesmane skeleton carries a hydroxy substituent at C-11 and has a double bond between C-4 and C-5.
A dipeptide obtained by formal condensation of the γ-carboxy group of glutamic acid with the amino group of Se -methylselenocysteine.
A nitrile that is L -glutamine in which one of the hydrogens attached to the amide nitrogen is replaced by a 2-cyanoethyl group.
A dipeptide composed of 3-cyano- L -alanine and L -glutamine joined by a peptide linkage formed from the side-chain of glutamine.
An L -glutamine derivative that is L -glutamine in which a hydrogen attached to the amide nitrogen is replaced by a 4-oxobutyl group.
An amino acid zwitterion obtained by transfer of a proton from the carboxy to the amino group of γ-glutamyl-γ-aminobutyraldehyde; major species at pH 7.3.
A dipeptide composed of glutamic acid and phenylalanine joined together by a peptide linkage.
A non-proteinogenic α-amino acid that is glutamine in which one of the hydrogens attached to the carboxamide nitrogen is replaced by a 4-aminobutyl group.
A dipeptide composed of glutamic acid and threonine joined by a peptide linkage.
