From German, probably a contraction of Essigäther acetic ether, from Essig vinegar (ultimately from Latin acētum) + Ätherether.
APAKAH MAKSUD ESTER dalam CORSICA?
Ester
Ester adalah sebatian kimia yang terdiri daripada karbonyl bersebelahan dengan ether linkage. Mereka diperolehi dengan bertindak balas dengan oxoacid dengan sebatian hidroksil seperti alkohol atau fenol. Ester biasanya berasal daripada asid anorganik atau asid organik di mana sekurang-kurangnya satu -OH digantikan oleh kumpulan -O-alkil, dan yang paling biasa dari asid karboksilik dan alkohol. Iaitu, ester dibentuk dengan menghidupkan asid dengan alkohol. Esters ada di mana-mana. Lemak dan minyak yang paling alami adalah asid lemak gliserol. Esters dengan berat molekul yang rendah biasanya digunakan sebagai wangian dan dijumpai dalam minyak dan pheromone penting. Phosphoesters membentuk tulang belakang molekul DNA. Ester nitrat, seperti nitrogliserin, dikenali dengan bahan peledaknya, manakala poliester adalah plastik penting, dengan monomer yang dikaitkan dengan molekul ester.
Definisi ester dalam kamus Corsica
Takrif ester dalam kamus adalah mana-mana satu kelas sebatian yang dihasilkan oleh tindak balas antara asid dan alkohol dengan penghapusan air. Ester dengan berat molekul yang rendah, seperti etil asetat, biasanya cecair wangi yang tidak menentu; lemak adalah ester padu.
