Ventajas y desventajas del aceite de pescado como Triglicérido y Etil Ester
Reseña Desde que el mercado de los Omega‐3 de aceite de pescado entró en la vida del consumidor, ha existido gran controversia sobre cuál es la forma química más beneficiosa para el organismo, si en forma de triglicérido o en forma de etil ester. A pesar de que ambas formas químicas han demostrado ser bastante beneficiosas para la salud, existe todavía una disputa principalmente debido al marketing que se maneja en esta industria. Es importante entender la diferencia en la estructura química tanto del triglicérido (TG) como el etil ester (EE). Triglicéridos Triglicéridos son la forma molecular natural de las grasas que se encuentran en los alimentos. Por ejemplo los omega‐3 presentes en el pescado EPA & DHA están como triglicéridos. Consisten de una columna vertebral de glicerol unida a tres ácidos grasos. En el caso del aceite de pescado, los ácidos grasos presentes mayoritariamente son el eicosapentanoico (EPA) y docosahexanoico (DHA). Los ácidos grasos se oxidan rápidamente por lo que la columna de glicerol ayuda a estabilizar las moléculas de grasas y evitar la oxidación.

A continuación una estructura de un triglicérido.

Etil Esteres
Los etil ésteres son una forma alternativa de grasas que son derivadas al reaccionar ácidos grasos libres con etanol. Durante este proceso, algunos ácidos grasos son separados de su columna natural de glicerol y vinculados a una molécula de etanol. En este proceso llamado trans‐esterificación se producen los etil ésteres de aceite de pescado (fish oil EE).

    Esters are carboxylic acid derivatives in which the acyl carbon bears an ether group instead of the hydroxy group. Esters are synthesized by different methods such as an Sn2 process where a carboxylic acid is treated with a strong base followed by an alkyl halide. Fischer Esterification is a nucleophilic acyl substitution reaction that converts a carboxylic acid into an ester when the carboxyl group of an acid and the hydroxyl group of an alcohol are condensed with the expulsion of a water molecule. The by product is removed to exploit Le Chatelier’s principle in order to favor the formation of the ester over the starting material.…

    The technique for esterification that was employed in the experiment was to use a reflux apparatus (Figure 1) while heating in order to evaporate out water to drive our reaction into the product favored direction. The starting material of isopentyl alcohol (1.0 mL) and excess glacial acetic acid(1.5 mL, 17.6M) were eppendorf pipetted into a 5 mL conical vile. This mixture was acid catalyzed by the addition on two drops of H2SO4. The mixture was then heated to 150-160⁰C in order to increase energy for esterification to occur over a period of 60- 75 minutes.…

    Isopentyl alcohol (0.787 g, 1.2 mL, 8.93 mmol), acetic acid (1.574 g, 1.5 mL, 26.20 mmol), and sulfuric acid (0.368 g, 0.2 mL, 3.75 mmol) was added to a 5 mL conical vial containing a spinvane. The vial was connected to a water condenser and refluxed for 60 min. The cooled mixture was washed with 5% sodium bicarbonate (2 x 1.0 mL). Sodium sulfate was added to the vial and the crude ester was removed and transferred to a clean vial. The vial was sealed and allowed to stand for 48 hr at rt. The clear liquid was distilled using a Hickman still and hot plate. The purified ester was removed from the still head to yield isopentyl acetate (0.29 g, 25%) and observed as a clear liquid. bp 140°C (lit1 142°C).…

    Omega-3 fatty acids refer to a set of polyunsaturated fatty acids that include docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), which is found in fish; alpha-linolenic acid (ALA), which is obtained from plants and Krill oil. Unlike the concentration in the level of fats in foods such as meat and butter that can increase the levels of unhealthy cholesterol, these fats are healthy because they help the human body to lower levels of unhealthy cholesterols as well as reducing the inflammation in the body (Allport 12).…

    Esters are in a lot of natural products like flowers, spices and fruits. They are usually used in artificial flavorings. Carboxylic esters help amplify the sensory effect of esters. Isopentyl acetate is made from the direct esterification of acetic acid and isopentyl alcohol. The direct esterification of acetic acid and isopentyl alcohol is an equilibrium reaction that shifts the product to the side by using the excess of one of the starting reagents. Acetic acid usually used in excess because it is easier to remove from the reaction. The excess acetic acid and the remaining isopentyl alcohol are removed through extraction with water and sodium bicarbonate, during the isolation step. Anhydrous sodium sulfate is used to dry the…

    The purpose of this experiment is to synthesize isopentyl ester by an esterification reaction between a carboxylic acid and an ester. Carboxylic esters, like isopentyl acetate, are normally used to create artificial flavors. In the preparation of isopentyl acetate, esterification of acetic acid and isopentyl alcohol occurs. Esterification is an equilibrium shift to the product side using an excess of one of the starting components. In this experiment, the excess reagent is acetic acid because it is not expensive and can easily be removed for the reaction. The acetic acid and isopentyl alcohol are removed by extraction with sodium bicarbonate and water. The limiting reagent is isopentyl alcohol. A limiting reagent is completely consumed when…

    PURPOSE: The purpose of this experiment was to illustrate the extraction of a solid natural product from its natural source by partition with the aid of an organic solvent. Extraction is the process by which a compound or mixtures of, is transferred by separation from one phase into another. In this case, the major triglyceride contains a single fatty acid identified as myristic acid. It is a substituent of the triglyceride called trimyristin, which embodies 20-25% of the dried weight of ground nutmeg we will eventually use in this experiment. The purpose of this lab is to extract trimyristin from nutmeg with the organic substance, diethyl ether, to evidently produce trimyristin with a small portion of myristicin (solid-liquid extraction). Also, it is good to know that due to impurity the best way purify the product of trimyristin is by recrystallization through hot acetone.…

    Acetylsalicylic acid is the active pharmaceutical ingredient in aspirin and can be synthesized by the esterification reaction of salicylic acid and acetic anhydride in the presence of an acid catalyst. An esterification reaction is when an acid is converted into an ester by combining with an alcohol and removing a water molecule. When heating the salicylic acid mixture in the warm water bath, the mixture should be removed from the bath within 8 minutes, to reduce the chance of the acetylsalicylic acid decomposing. The purpose of this procedure is to isolate acetylsalicylic acid from its accompanied acid catalyst, unreacted salicylic acid, acetic anhydride, and other impurities. Their removal can be done by crystallization, a purification technique in which, upon cooling, product crystals will be separated from impurities that are present in the solution, which can then be filtered off using a vacuum. In this procedure, acetic anhydride is used to wash the reactants, and phosphoric acid is used as a catalyst to…
