Match the following. 1. vitamin c deficiency pellagra 2. thiamine deficiency (hyphenated) rickets 3. vitamin d deficiency scurvy 4. niacin deficiency albumen 5. vitamin a (retinol) deficiency beri-beri 6. milk protein casein 7. egg white protein glycogen 8. starch stored in liver and muscle keratomalacia

This question is in the context of diseases acquired from the deficiency of these vitamins.

Vitamin C deficiency causes scurvy and this is characterized by decreased collagen production leading to easy bleeding of the soft tissues. Thiamine deficiency causes beriberi which is characterized primarily by symptoms associated with heart failure. Vitamin D deficiency causes rickets which is the abnormal softening of the bones of children (vitamin D deficiency causes osteomalacia in adults). Niacin deficiency causes pellagra characterized by diarrhea, dermatitis, dementia, and even death if untreated. Vitamin A deficiency causes keratomalacia which causes death of corneal cells leading to cloudy vision. 

The others are to be matched by description. Milk protein is called casein. Egg white protein is called albumen. Lastly, starch stored in the liver and muscle is called glycogen.
