There are 20 different tRNA molecules, one for each of the 20 amino acids found in protein
There are 20 different tRNA molecules, one for each of the 20 amino acids found in protein. During protein synthesis, the job of a tRNA molecule is to carry its particular amino acid to the growing protein chain and find the correct amino acid position there. It does this by matching a 3- letter anticodon on the tRNA to a complementary 3-letter codon on mRNA. Below, in a diagram of a ERNA molecule, nucleotides are represented by small circles, some...

reaction scheme. Thanks.
Reductive amination is usually a one-pot procedure during which a carbonyl compound is reacted with ammonia or a primary amine to yield an imine. Subsequently the imine is reduced in situ to an amine. The procedure has application in synthesis of biologically active molecules. In this experiment the imine will be prepared quantitatively through a solvent free reaction (green chemistry) between ortho-vanilin and para-toluidine. The imine is...

1. Reductive amination (Carey, Section 22.10) is an important C-N bond forming strategy widely used in the synthesis of biologically active natural product. It's a powerful and reliable strategy that avoids the problem of overalkylation that often accompanies direct alkylation of amines with alkyl halides (Figure 1). secondary amine r tiary amine quemary sa Figure 1: Yields are generally poor as product amines are more nucleophilic and can also react with halide. The result is often a mixture of amines...

Compound A is a novel polyester amide) copolymer that can be used as a bioabsorbable coating for the controlled release of drugs. A is a copolymer of four monomers, two of which are amino acids or amino acid derivatives. The body's enzymes recognize the naturally occurring amino acids in the polymer backbone, allowing for controlled enzymatic breakdown of the polymer and steady release of an encapsulated drug. Draw the four monomers used to synthesize A in the order that they...

Synthesis is a major area of organic chemistry which often requires multiple material to a target compound. A systematic way to propose a synthesis e chemistry which often requires multiple steps to convert one organic systematic way to propose a synthesis is to work backwards from the target compound to a readily available starting material.
