Organic ester
* Ester chemists word to describe a particular chemical bonding configuration.
* Ester is an organic compound
  - organic matter
* Esters also have an important function in organic synthesis
  - remarkable applications in everyday life
* Esters are a class of compound that can help to illustrate the correlation between smell and flavor
  - ubiquitous class of aroma compounds present in many fruits
  - very important functional group
  - aromas and flavors in the beer that are a byproduct of fermentation
* Esters are compounds formed when carboxylic acids react with alcohols
  - that are sort of like alcohols bonded to acids
  - derived from carboxylic acids
  - named as derivatives of the carboxylic acid from which they are formed
  - organic molecules
  - present in small quantities after distillation, and are also formed during aging
  - the most common functional group
  - usually non-staining and cosmetically easier to work with than other chemical absorbers
  - very common in nature and an important part of Organic chemistry courses
* Esters can also do many reactions
  - react with amines or ammonia to form amides
  - degrade most rapidly
  - enolize too , and their enolate ions do the same things that ketone-enolates do
* Esters have a very sweet fruity smell
  - important medical uses
  - two carbon chains separated by an 'ether' oxygen
  - often have a fruity taste or odor
  - react in the presence of an acid or base to give back the alcohol and a salt
  - require an organic acid and an alcohol to condense by the elimination of water
  - usually have a pleasant fruit-like flavor
* Esters vary from low to high
  - only in their ability to reduce a steroid's water solubility
* Many esters are very fragrant
  - occur naturally and can be derived from a variety of plants
* Some esters also have useful physiological effects
  - have recognizable odors and are used in food flavorings.
  * Esters are a very important functional group. They can be found in many substances. They are very common in fats and oils. They sometimes have a very strong, nice smell. They can be used to make perfumes. Polyesters are found in plastics.
  * Esters can also do many reactions. It is very easy to change the ether part of the molecule with another similar one. It is also possible to reduce the ester to a ketone or an alcohol, which can do many different reactions. Nucleophilic addition is also a good reaction, though a bit more difficult than with ketones

### organic ester:

Glyceride
* are ester
  - fats and oils that are esters of glycerol with one or more fatty acids
  - fuel
  - lipids in which fatty acids are attached to the glycerol molecule
  - part of fat
* contain fatty acids and glycerol.
* is ester
* occur naturally in oils and fats.

Lactate
* act as a bacteriostat by increasing the lag phase or dormant phase of microorganisms.
* are a partial measure of the amount of anaerobic work that is performed in a task.

Organic ethyne
* An ethyne is an organic compound
* Ethynes readily form compounds with metal.

Organic furan
* A furan is an organic compound
* Furan produces liver cancer in rats and mice and therefore has been studied in detail.
* Furans are chemical compounds
  - organic compounds
  - similar chemicals and are often found with dioxins
  - structurally similar to dioxins and share many of their toxic effects
  - very similar to dioxins
  - have one or two phenyl rings connected to a furan ring
* Some furans are nearly identical to dioxins in structure and toxicity.

Organic glycoside
* A glycoside is an organic compound
* Glycosides are a group of sugar derivatives found widely in plants
  - important sugars for the proper functioning of the heart and blood stream
  - molecules in which a non-sugar chemical is bound to a sugar
* Glycosides are very common in nature
  - varied in structure and have a wide range of functions
  - neutralize glucose capturing inhibitor that arises in blood during stress
