ester Definition
Noun
- an organic compound made by replacing the hydrogen of an acid by an alkyl or other organic group. Many naturally occurring fats and essential oils are esters of fatty acids.
ester Example
- These esters are readily hydrolysed and yield the monoand di-alkylimalonic acids which, on heating, are readily decomposed, with evolution of carbon dioxide and the formation of monoand di-alkyl acetic acids. ( ये एस्टर आसानी से जल-अपघटित हो जाते हैं और मोनो और डाइ-एल्काइलमेलोनिक एसिड उत्पन्न करते हैं, जो कार्बन डाइऑक्साइड के विकास और मोनो और डाय-एल्काइल एसिटिक एसिड के निर्माण के साथ, गर्म होने पर आसानी से विघटित हो जाते हैं। )
- Of other syntheses of true benzene derivatives, mention may be made of the formation of orcinol or [3 s]-dioxytoluene from dehydracetic acid; and the formation of esters of oxytoluic acid (5-methyl3-oxy-benzoic acid), C6 H3 CH3. ( सच्चे बेंजीन डेरिवेटिव के अन्य संश्लेषणों में, डिहाइड्रैसेटिक एसिड से ओर्सिनॉल या [3 एस] -डाइऑक्साइटोल्यूइन के गठन का उल्लेख किया जा सकता है; और ऑक्सीटोलुइक एसिड (5-मिथाइल3-ऑक्सी-बेंजोइक एसिड), C6 H3 CH3 के एस्टर का निर्माण। )
- The tissue was dried by grinding with anhydrous sodium sulfate and extracted with several volumes of hexane to remove carotenoids, retinols, and retinyl esters. ( ऊतक को निर्जल सोडियम सल्फेट के साथ पीसकर सुखाया गया और कैरोटीनॉयड, रेटिनॉल और रेटिनिल एस्टर को हटाने के लिए हेक्सेन के कई संस्करणों के साथ निकाला गया। )
More Sentence
- As a useful preliminary it is convenient to divide heterocyclic ring systems into two leading groups: (I) systems resulting from simple internal dehydration (or similar condensations) of saturated aliphatic compounds - such compounds are: the internal anhydrides or cyclic ethers of the glycols and thioglycols (ethylene oxide, &c.); the cyclic alkyleneimides resulting from the splitting off of ammonia between the amino groups of diaminoparaffins (pyrrolidine, piperazine, &c.); the cyclic esters of oxycarboxylic acids (lactones, lactides); the internal anhydrides of aminocarboxylic acids (lactams, betaines); cyclic derivatives of dicarboxylic acids (anhydrides, imides, alkylen-esters, alkylenamides, &c.).
- By actual observations it has been shown that ether, alcohol, many esters of the normal alcohols and fatty acids, benzene, and its halogen substitution products, have critical constants agreeing with this originally empirical law, due to Sydney Young and Thomas; acetic acid behaves abnormally, pointing to associated molecules at the critical point.
- Using a photo fragmentation process that breaks an ester bond we demonstrate the system's ability to produce simple lipids (carboxyl acid).
- Recent researches have shown that the law originally proposed by Kopp - " That the specific volume of a liquid compound (molecular volume) at its boiling-point is equal to the sum of the specific volumes of its constituents (atomic volumes), and that every element has a definite atomic value in its compounds " - is by no means exact, for isomers have different specific volumes, and the volume for an increment of CH 2 in different homologous series is by no means constant; for example, the difference among the esters of the fatty acids is about 57, whereas for the aliphatic aldehydes it is 49.
