L-Glu (Otbu) -Otbu-OH

Ester ikozwe muri esterisation reaction ya acide organique cyangwa aside organic cyangwa alcool.Inzoga cyangwa fenol cyangwa acide anhydride, inzoga na Ethylene, aside irike yubusa hamwe nibikomoka kuri azote bishobora nanone kubyara ester.Hydrogene kuri alfa-karubone muri molekile ya ester itakaza inzoga ya molekile hamwe nindi ester ya molekile mubihe bya alkaline kugirango itange β-keto ester, ibyo bita ester contraction reaction.Kurugero, acetyl acetate ikorwa kugirango habeho acetyl Ethyl acetate.Iyi reaction ningirakamaro cyane muri synthesis.

Izina rya ester rikomoka ku izina rihuye na aside ya karubonike na alcool cyangwa fenol, nka "aside runaka na ester runaka".Uruziga ruzenguruka rwitwa lactone (lactone).Imiterere yimiti ya ester isa na amyl niche anhydride, ikunda hydrolysis, alcool na ammonia reaction.Ester nkeya-ester ni impumuro nziza kandi ihindagurika idafite ibara, kandi ester yateye imbere irakomeye.Estes ni umusemburo wingenzi nibikoresho fatizo ngengabihe, kandi est est ni ibiyobyabwenge ubwabyo.Ukurikije ubwoko bwa acide, ester irashobora kugabanywamo aside estorganic ester na ester acide organic.Etate, Ethyl acetate ni ibinure bya ester, acetate ni ester ya aromatic, na namanonate ni cyclic ester.
