Types
Galactose is converted into glucose by the action of three enzymes, known as the Leloir pathway. There are diseases associated with deficiencies of each of these three enzymes:
| Type | Diseases Database | OMIM | Gene | Locus | Enzyme | Name |
| Type 1 | 5056 | 230400 | GALT | 9p13 | galactose-1-phosphate uridyl transferase | classic galactosemia |
| Type 2 | 29829 | 230200 | GALK1 | 17q24 | galactokinase | galactokinase deficiency |
| Type 3 | 29842 | 230350 | GALE | 1p36-p35 | UDP galactose epimerase | galactose epimerase deficiency, UDP-Galactose-4-epimerase deficiency |

Famous quotes containing the word types:
“He’s one of those know-it-all types that, if you flatter the wig off him, he chatter like a goony bird at mating time.”
—Michael Blankfort. Lewis Milestone. Johnson (Reginald Gardner)
“As for types like my own, obscurely motivated by the conviction that our existence was worthless if we didn’t make a turning point of it, we were assigned to the humanities, to poetry, philosophy, painting—the nursery games of humankind, which had to be left behind when the age of science began. The humanities would be called upon to choose a wallpaper for the crypt, as the end drew near.”
—Saul Bellow (b. 1915)
“He types his laboured column—weary drudge!
Senile fudge and solemn:
Spare, editor, to condemn
These dry leaves of his autumn.”
—Robertson Davies (b. 1913)
