BiochemistryThe eye change include an increase in blood vessels and inflammation of the conjunctivae, cornea is invaded by capillaries, producing opaque areas and even ulceration. Dermatitis characterized by a greasy and scaly reddened lesion develops on the skin around the nasolabial folds and may extend to a butterfly shape on the cheeks. There many also be lesions at the corners (canthi) of the eyes and lobes of the mouth.

BiochemistryThe synthesis of urea takes place in the liver by the process called ''Ornithine
cycle'' or "Urea cycle"
This cycle was discovered by Hans Krebs and Kurt Henseleit in the year 1932.
The Ornithine cycle is completed in 5 steps:
1. Conversion of ammonia into carbamoyl phosphate
2.The transfer of carbamoyl group from carbamoyl phosphate to ornithine
3. Releasing of the formed citrulline into the cytosol
4. Cleavage of argininosuccinate
5. Hydrolysis of Arginine: The final step involves the hydrolysis of Arginine
into urea and ornithine
Arginase is the sixth and final enzyme of this cycle.
