Is transesterification an equilibrium reaction?
The reaction is called “transesterification” because it is a process of converting one kind of ester (triglycerides) into another kind (methyl fatty acid esters). Transesterification is a reversible reaction and will reach equilibrium as the reaction proceeds (Figure 2).
What is the geometry of the intermediate formed in the mechanism of transesterification?
2. What is the geometry of the intermediate formed in the mechanism of transesterification? Explanation: In the transesterification mechanism, the carbonyl carbon of the starting ester reacts to give a tetrahedral intermediate, which either reverts to the starting material, or proceeds to the transesterified product.
What is transesterification in 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.
Is transesterification a hydrolysis reaction?
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 a spliceosome and what does it do?
Spliceosomes are multimegadalton RNA–protein complexes responsible for the faithful removal of noncoding segments (introns) from pre-messenger RNAs (pre-mRNAs), a process critical for the maturation of eukaryotic mRNAs for subsequent translation by the ribosome.
How does gene splicing work?
Gene Splicing. In gene splicing, scientists take a specific restriction enzyme to unravel a certain strand or strands of DNA. The DNA’s double helix structure is then separated into single strands.
Is transesterification the same as Fischer esterification?
It is two step process. Esterification includes an ester as the end product whereas transesterification includes an ester as a reactant.
What are Fischer projections used for?
Fischer projections are a convenient way to depict chiral molecules (see optical activity) and distinguish between pairs of enantiomers (see racemic mixture). They are most often used to depict isomers of the sugars.
