(a)

Summary Introduction

To determine: The atom of urea in which the isotope will be found.

Introduction:

The breakdown of nitrogenous compounds produces crystalline compounds which is colorless and is known as urea. The ammonia is the most common form of nitrogenous waste. It is mostly found in mammals’ urine.

(b)

Summary Introduction

To determine: The atom of succinate in which the isotope will be found.

Introduction:

The metabolic pathway in humans includes the succinate in many of the reactions which also involves the enzyme succinate dehydrogenase. It is also called as the Ester or salt form of succinic acid.

(c)

Summary Introduction

To determine: The atom of arginine in which the isotope will be found.

Introduction:

Arginine is one of the most essential amino acid. The person who is on diet lacks arginine in the urea cycle, so there will be no conversion of ammonia to urea. Arginine plays an important role in urea formation.

(d)

Summary Introduction

To determine: The atom of citrulline in which the isotope will be found.

Introduction:

Citrulline is the amino acid which aids in the flow of blood in the body. It is made in the body. Citrulline maintains the health of heart and body by improving the flow of blood.

(e)

Summary Introduction

To determine: The atom of ornithine in which the isotope will be found.

Introduction:

Ornithine is one of the amino acid which can replace arginine because ornithine is proteogenic and it can easily be converted into arginine through urea cycle. This conversion removes the toxicity which is due to the accumulation in the body.

(f)

Summary Introduction

To determine: The atom of aspartate in which the isotope will be found.

Introduction:

Aspartate is the amino acid which is salt or ester of aspartic acid. Similarly, succinate is salt or ester of succinic acid. It plays a vital role in the cycle of urea.

Students have asked these similar questions

The beta-lactamase hydrolyzes the lactam-ring in penicillin. Describe the mechanism of hydrolysis, insuring to include the involvement of S, D, & K in the reaction sequence. Please help

To map the active site of beta-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. Why doesn't D in this hexapeptide not participate in the hydrolysis of the beta-lactam ring even though S, K, and D are involved in the catalyst?
