Study Notes
Essential Trace Elements
- Copper, zinc, and iron are essential trace elements.
- Chromium, cobalt, iodine, manganese, molybdenum, and selenium are essential ultratrace elements.
Functions of Essential Trace Elements
- Cellular respiration
- Neurotransmitter regulation
- Collagen synthesis
- Development of vascular and skeletal structures and CNS
- Protection from free radical damage
Copper
- Ceruloplasmin is a protein that transports copper.
- Wilson's disease is a condition caused by copper toxicity.
- Deficiency in copper can lead to malnutrition, Menke's syndrome (kinky hair), and other disorders.
Iron
- Iron is the fourth most abundant element in the earth's crust.
- It is stored as ferritin (soluble) and hemosiderin (insoluble).
- Transferrin is a protein that transports iron.
- Diurnal variation: iron levels are higher in the morning.
- Iron deficiency can lead to iron deficiency anemia (microcytic, hypochromic RBCs).
- Iron is a co-factor for over 300 enzymes.
Chromium
- Chromium is an important component of glucose tolerance factor.
- It potentiates insulin action and is involved in glucose and lipid metabolism.
- Cr(III) is an essential nutrient, while Cr(VI) is a recognized allergen and respiratory tract irritant.
Iodine
- Iodine is necessary for the synthesis of thyroid hormones.
- Thyrotoxicoses can occur due to iodine toxicity.
- Iodine deficiency can lead to goiter, hypothyroidism, cretinism, and congenital myxedema.
Vitamins
- Vitamins are organic compounds that occur in natural foods.
- They are classified into two groups: water-soluble (vitamins B and C) and fat-soluble (vitamins A, D, E, and K).
- Vitamins have various functions, including:
- Antioxidant functions (vitamins A, C, and E)
- Energy production (vitamins B and C)
- Blood clotting (vitamin K)
- Bone health (vitamin D)
Minerals
- Minerals are essential for various bodily functions, including:
- Providing a suitable medium for protoplasmic activity
- Regulating osmotic phenomena
- Maintaining acid-base equilibrium
- Serving as a primary component of some tissues
- Participating in enzymatic reactions
- Minerals are classified into two groups: macro-minerals (Na, K, Ca, Mg, P, Cl) and micro-minerals (essential trace elements and toxic elements).
