The peptide Leu-Cys-Arg-Ser-Gln-Met is subjected to Edman degradation. In the first cycle the peptide first reacts with phenylisothiocyanate under basic conditions. The product of this reaction is incubated with anhydrous trifluoroacetic acid and subsequently with an aqueous acid. What are the products generated in the first cycle. PTH-Leu-Cys-Arg-Ser-Gln-Met PTH-Leu, PTH-Cys, PTH-Arg, PTH-Ser, PTH-GIn, and PTH-Met PTH-Leu and Cys-Arg-Ser-Gln-Met PTH-Met and Leu-Cys-Arg-Ser-GIn-Met PTH-Leu-Cys and PTH-Arg-Ser-Gln-Met O O O O
Nucleotides
It is an organic molecule made up of three basic components- a nitrogenous base, phosphate,and pentose sugar. The nucleotides are important for metabolic reactions andthe formation of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).
Nucleic Acids
Nucleic acids are essential biomolecules present in prokaryotic and eukaryotic cells and viruses. They carry the genetic information for the synthesis of proteins and cellular replication. The nucleic acids are of two types: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The structure of all proteins and ultimately every biomolecule and cellular component is a product of information encoded in the sequence of nucleic acids. Parts of a DNA molecule containing the information needed to synthesize a protein or an RNA are genes. Nucleic acids can store and transmit genetic information from one generation to the next, fundamental to any life form.
