Which of the following is an example for transesterification reaction?
The reverse reaction, methanolysis, is also an example of transesterification. This process has been used to recycle polyesters into individual monomers (see plastic recycling). It is also used to convert fats (triglycerides) into biodiesel. This conversion was one of the first uses.
What is transesterification and where it is used?
Transesterification is the displacement of alcohol from an ester by another one in a process similar to hydrolysis, except that alcohol is used instead of water [18]. This process has been widely used to reduce the high viscosity of triglycerides.
What is esterification transesterification?
Esterification is any reaction (typically between an fatty acid and an alcohol) that results in the production of an ester, while transesterification is the reaction of an ester with an alcohol in order to replace the alkoxy group; it is used in the synthesis of polyesters and in the production of biodiesel.
Is transesterification a hydrolysis reaction?
Ester compounds can be transformed from one type of ester into another via a reaction called transesterification, which is basically another ester hydrolysis reaction. This reaction can occur either under basic or acidic conditions and the reaction mechanism depends on which conditions are used.
What is transesterification in RNA splicing?
The bonding of the guanine and adenine bases takes place via a chemical reaction known as transesterification, in which a hydroxyl (OH) group on a carbon atom of the adenine “attacks” the bond of the guanine nucleotide at the splice site.
Which is the process that removes introns from RNA?
In splicing, some sections of the RNA transcript (introns) are removed, and the remaining sections (exons) are stuck back together. Some genes can be alternatively spliced, leading to the production of different mature mRNA molecules from the same initial transcript.
What is the process of RNA splicing?
RNA splicing is a process that removes the intervening, non-coding sequences of genes (introns) from pre-mRNA and joins the protein-coding sequences (exons) together in order to enable translation of mRNA into a protein.
What is process of splicing?
Splicing occurs during protein synthesis, and involves cutting out and rearranging sections of mRNA. Before mRNA is used as instructions to make a protein, it can be cut into smaller sections and re-arranged in a process called splicing.
What is the chemical composition of biodiesel?
Although a mixture, the basic biodiesel chemical formula is C17H34O2, with the ester group –CO2CH3 at the end of the long carbon chain.
Why is NaOH used as a catalyst in transesterification?
CH3OH (methanol) and NaOH (sodium hydroxide) as base catalyst are mostly used in this process because of their lowest costs, higher reaction rates and higher yields. From the WCO generation of about 80 lites per week, yield for biodiesel production is considered in the range of 80-90%.
