Alcaptonuria is a condition in which large quantities of homogentisic acid are excreted into the urine, which turns black on standing. Under normal conditions, the amino acid tyrosine is converted through a series of enzymatic reactions to fumarate and acetoacetate (La Du, 1966). Garrod noted that when ...

Alcaptonuria is a rare hereditary disease characterized by the presence of homocysteic acid in the urine and subsequent development of degenerative joint disease (Krane, 1984). The disorder is accompanied by pigmentation of the connective tissues, particularly of cartilage. The metabolic defect is caused by a deficiency in the enzyme homogentisic acid oxidase, which catalyzes the conversion of homogentisic acid to maleylacetoacetic acid (LaDu, 1978). Homogentisic ...

Alcaptonuria is a non-serious genetic flaw that can be detected easily by a blackening of the urine. It is the result of a blockage caused by the mutation of an enzyme involved in the catabolism of an amino acid, tyrosine, this blockage leading to the accumulation of homogentisic acid, the polymerization of which gives rise to a brownish color. The patient 286 DISCOVERING ...

alcaptonuria. (alkaptonuria) n. the congenital absence of an enzyme, homogentisic acid oxidase, that is essential for the normal breakdown of the amino acids tyrosine and phenylalanine. Accumulation of *homogentisic acid causes dark brown discoloration of the skin and eyes (ochronosis) and progressive damage to the joints, especially of the spine. The gene responsible for the condition is recessive, so that a child is affected only if both parents are carriers of the defective gene.
