A key concern in urea cycle disorders is the toxic accumulation of:

		ammonia.
		homocysteine.
		isovaleric acid.
		phenylalanine.

Expert Solution

A key concern in Urea cycle disorders is the toxic accumulation of:

Answer : Ammonia ( first option)

Urea cycle disorders are a group of inherited disorders characterised by lack of one or more enzymes, that helps in the breakdown of nitrogenous products, end prroducts of protein metabolism, resulting in accumulation of nitrogenous wastes , especially Ammonia. Along with ammonia , glutamine and Alanine also may get accumulated.

Other options: ( are wrong options)

Homocysteine: It is an Aminoacid . It is not a nitrogenous waste. Homocysteine is a homologue of cysteine, amino acid.

Isovaleric acid: It is a natural fatty acid with pungent smell, found in a wide variety of plants and essential oil, whose volatile esters are used in perfumery.

Phenylalanine : An essential amino acid gound in most of the animal protein. It is essential for growth. The inability to metabolize it leads to phenylketonurea.

A. Individuals with urea cycle disorders have glucose intravenously injected into their blood stream. How could maintaining high levels of glucose in the blood stream partially reduce the accumulation of ammonia in individuals with a urea cycle disorder? B. Please explain why individuals with defects in the malate-aspartate shuttle would exhibit increased levels of ammonia in their bloodstream based upon the reactions of the urea cycle?

Urea (CH4N2O) is a common fertilizer that can be synthesized by the reaction of ammonia (NH3) with carbon dioxide as follows: 2NH3(aq)+CO2(aq)→CH4N2O(aq)+H2O(l) In an industrial synthesis of urea, a chemist combines 120.6 kg of ammonia with 211.4 kg of carbon dioxide and obtains 181.4 kg of urea. Part A) Determine the limiting reactant. Part B)Determine the theoretical yield of urea. Part C) Determine the percent yield for the reaction.
