| tyrosin | <physiology> A white crystalline nitrogenous substance present in small amount in the pancreas and spleen, and formed in large quantity from the decomposition of proteid matter by various means, as by pancreatic digestion, by putrefaction as of cheese, by the action of boiling acids, etc. Chemically, it consists of oxyphenol and amidopropionic acid, and by decomposition yields oxybenzoic acid, or some other benzol derivative.

| tyrosinaemia | A disorder consisting of elevated blood concentrations of tyrosine, enhanced urinary excretion of tyrosine and tyrosyl compounds, hepatosplenomegaly, nodular cirrhosis of the liver, multiple renal tubular reabsorptive defects, and vitamin D-resistant rickets; autosomal recessive inheritance.
