The interaction of sulfur mustard with aminoacids and proteins has been investigated in this study. Rats were injected with sublethal doses of sulfur mustard subcutaneously and intraperitoneally. At different time intervals, plasma and urine samples were collected. The binding affinity of sulfur mustard with urinary and plasma proteins and enzymes was studied for the first time using non-i...

Amino acids are one of the most necessary substances in intracellular metabolic processes.aromatic aminoacids such as phenylalanine and tyrosine are precursor of melanin so are important materials for the skin pigmentation.metabolic disorders in the melanin synthesis causes milky macules on the skin of patients,known as vitiligo.these patients are hypersensitive to sunlight and consequently at ...

Maple syrup urine disease (MSUD) is an autosomal recessive metabolic disorder caused by a deficit of oxidative decarboxylation of branched-chain aminoacids. It leads to a build-up of leucine, isoleucine, valine, and toxic metabolites in blood and urine, progressing to acute and chronic brain dysfunction. The first symptoms appear in early childhood and are characterized by sweet-smelling urine,...

Cushny in 1917 first remarked on the extensive amino acid reabsorption which occurs in the nephron. Although many workers since then have studied the nature and localization of the reabsorptive mechanism, progress has been slow because of the technical difficulties of micropuncture work. The bulk of filtered amino nitrogen is reabsorbed in the proximal tubule although the possibility of there b...

organic acid occur as physiologic intermediates in variety of intracellular metabolic pathways, such as catabolism of aminoacid, mitochondrial β oxidation of fatty acids, tricarboxilic acid cycle, and cholestrol and fatty acid biosynthesis. the classical organic aciduria represent the pursuit of abnormalities of aminoacid degradation beyond deamination their diagnostic hallmark is an accumulati...
