Explanation
Homogentistic acid is an intermediate in the metabolism of tyrosine and phenylalanine. In individuals with alkaptonuria, a genetic disorder, homogentisic acid accumulates in the body due to a deficiency in the enzyme homogentisate 1,2-dioxygenase, leading to its excretion in urine and various health issues including dark pigmentation of connective tissues.
