Lipids represent about 3 to 5 percent of the dry weight of lens. In human lens cholesterol is about 50 percent of lipids followed by phospholipids (45%) and glycosphingolipids and ceramides (5%).
Excessive glycosylation of lens proteins takes place and glucose is converted to sorbitol by auto-oxidation and protein binding (aldose reductase). These chemical changes are present in human diabetic cataract. However, glucose oxidation to sorbitol plays a more important role in the rapidly developing diabetic cataract. Whereas, abnormal protein glycosylation is of greater significance in the slowly developing senile cataracts in patients with diabetes. REFERENCES 1. Garg Ashok.
