Concept explainers
Interpretation:
The IUPAC names of five
Concept introduction:
Isomers:
The compounds with the same molecular formula but different in structure is called as Isomers
IUPAC naming for
International Union of pure and applied chemistry has formulated general rules for nomenclature of organic compounds.
Systematic name of chemical should contain 4 essential parts.
Prefix: To specify the location and identity of various substituent groups in the molecule.
Locant: To specify the location of the primary
Parent: To specify the main part of the molecule with the number of carbon atoms.
Suffix: To specify the primary functional group.
IUPAC Rule-1: Finding the parent hydrocarbon
IUPAC Rule-2: Numbering the carbon chain
IUPAC Rule-3: Assigning the prefix and the Locant
IUPAC Rule-4: Assembling the full name.

- You have isolated a protein and determined that the native molecular weight of the holoenzyme is 160 kD using size exclusion chromatography. Analysis of this protein using SDS-PAGE revealed 2 bands, one at 100 kD and one at 30 kD. Describe the architecture of the polypeptide component of this enzyme.arrow_forwardIn a cell free preparation of beta-lactamase, penicillin is hydrolyzed in a D2O enriched assay. After one round of catalysis, where would you anticipate finding Deuterium? please help thank youarrow_forwardTo map the active site of -lactamase, the enzyme was hydrolyzed with trypsin to yield a hexapeptide (P1) with the following amino acids. Glu, Lys, Leu, Phe, Met, and Ser. Treatment of P1 with phenyl isothiocyanate yielded a PTH derivative of phenylalanine and a peptide (P2). Treatment of P1 with cyanogenbromide gave an acidic tetrapeptide (P3) and a dipeptide (P4).Treatment of P2 with 1-fluoro-2,4-dinitrobenzene, followed by complete hydrolysis, yields N-2,4-dinitrophenyl-Glu. P1, P2, and P3 contain the active site serine. question: the b-lactamase hydrolyzes the lactam-ring in antibiotics like penicillin. Describe the mechanism, of hydrolysis, insuring to include the involvement of S, D, and K in the reaction sequence. Please help!arrow_forward
- Three of these amino acids participate in the proteolytic hydrolysis of polypeptides. Show the charge-relay network generated by the serine proteases and identify the nucleophilic species that initiates the hydrolysis. please help!arrow_forwardYou have isolated a protein and determined that the native molecular weight of the holoenzyme is 160 kD using size exclusion chromatography.
