Structure Of Proteins

Option 3: is the correct answer

Kwashiorkor is a severe form of protein malnutrition characterized by adequate calorie intake but insufficient protein consumption. It commonly affects children in regions experiencing famine or food scarcity. Symptoms include edema, irritability, an enlarged liver, and skin conditions. Unlike marasmus, which results from overall calorie deficiency, kwashiorkor specifically arises from a lack of protein, leading to impaired growth and development.
Characteristics of Kwashiorkor: Edema (swelling) due to low plasma protein levels Fatty liver (hepatomegaly) Dermatitis and hair discoloration Irritability and lethargy
Conclusion: Kwashiorkor is directly caused by protein deficiency, distinguishing it from other malnutrition-related diseases involving vitamin deficiencies or overall calories.
