Detailed explanation-1: -Alkaptonuria, or black urine disease, is a very rare inherited disorder that prevents the body fully breaking down two protein building blocks (amino acids) called tyrosine and phenylalanine.
Detailed explanation-2: -A defect in the HGD gene causes alkaptonuria. The gene defect makes the body unable to properly break down certain amino acids (tyrosine and phenylalanine). As a result, a substance called homogentisic acid builds up in the skin and other body tissues. The acid leaves the body through the urine.
Detailed explanation-3: -The name Alkaptonuria is derived from the Arabic word “alkali” (meaning alkali) and the Greek word meaning “to suck up oxygen greedily in alkali”. The name was created by Boedeker in 1859 after he discovered unusual reducing properties in the urine of a patient.
