It is more accurate to use the term galactosemia with the appropriate deficient enzyme, as suggested by Segal: `4e galactokinase deficiency galactosemia; transferase deficiency galactosemia; and epimerase deficiency galactosemia. The enzyme galactose-1-phosphate uridyl transferase (GALT) converts galactose-1-phosphate into glucose-1-phosphate, thus enabling further breakdown via glycolysis. These results are clinically significant in which of the following What is the purpose of Clinitest?
