Question

Why are proteins necessary in our food ? Name one protein deficiency
disease of young children

Answer 1

hair and nails are mostly made of protein. Your body uses it to build and repair tissue. You need it to make enzymes, hormones, and other body chemicals. It is an important building block of bones, muscles, cartilage, skin, and blood.

Kwashiorkor is a severe form of malnutrition, caused by a deficiency in dietary protein. The extreme lack of protein causes an osmotic imbalance in the gastro-intestinal system causing swelling of the gut diagnosed as an edema or retention of water.

Answer 2

Proteins are large and complex molecules or macronutrients and are made up of amino acids which are linked together by peptide bonds.

Explanation:

• Every cell in the body has protein as the major component. Proteins build and repair tissues. Proteins produce enzymes, hormones and other chemicals and carry out several enzymatic reactions.
• Bones, muscles, cartilage, skin and blood have proteins as the major building block. Proteins are needed for growth and maintenance of tissues, for biochemical and enzymatic reactions, providing structure to the cells of the body, maintaining pH of blood and other fluids in the body, balancing fluids, strengthening immune system, transporting and storing nutrients, and providing energy.
• Kwashiorkor is a disease caused by protein deficiency in young children. Symptoms of Kwashiorkor include change in skin and hair colour and texture, fatigue, repeated diarrhoea, loss of muscle mass, failure to gain weight, oedema in ankles feet and belly, liver enlargement, anaemia and pot belly.
