Discuss the functions, sources, deficiency diseases, and symptoms of key minerals like iron, zinc, calcium, and phosphorus.

Here is a discussion of the minerals, their functions, sources, deficiency diseases, and symptoms:

• Iron

  • Function: Essential component of hemoglobin, which transports oxygen in the blood. It is also involved in energy production.
  • Source: Red meat, liver, beans, spinach, fortified cereals.
  • Deficiency Disease: Anemia.
  • Symptoms: Fatigue, weakness, pale skin, shortness of breath, dizziness.

• Zinc

  • Function: Crucial for immune function, wound healing, DNA synthesis, and cell division. It also plays a role in taste and smell.
  • Source: Meat, shellfish, legumes, nuts, dairy products.
  • Deficiency Disease: Impaired immune function, growth retardation, delayed wound healing.
  • Symptoms: Hair loss, diarrhea, skin lesions, loss of appetite, impaired immune response.

• Calcium

  • Function: Primary component of bones and teeth, essential for muscle contraction, nerve transmission, and blood clotting.
  • Source: Dairy products (milk, cheese, yogurt), leafy green vegetables (kale, broccoli), fortified foods.
  • Deficiency Disease: Osteoporosis (in adults), Rickets (in children).
  • Symptoms: Brittle bones, muscle cramps, abnormal heart rhythm, numbness or tingling in fingers.

• Phosphorus

  • Function: Works with calcium to build strong bones and teeth. It is also vital for energy metabolism (as part of ATP) and is a component of DNA and RNA.
  • Source: Meat, fish, dairy products, nuts, legumes.
  • Deficiency Disease: Hypophosphatemia (rare, often due to underlying medical conditions).
  • Symptoms: Muscle weakness, bone pain, fatigue, confusion, loss of appetite.

A factor affecting enzymes:

• Temperature is a critical factor affecting enzyme activity. Enzymes have an optimal temperature at which they function most efficiently. Temperatures significantly above this optimum can cause the enzyme to denature, changing its shape and losing its ability to catalyze reactions. Temperatures below the optimum generally slow down enzyme activity without causing permanent damage.
