Study Notes

Sodium (Na)

Essential for nerve signal transmission and regulation of water levels in tissues and blood.
Sixth most common element on Earth, comprising 2.6% of the Earth's crust.
Predominantly found as sodium chloride (table salt).

Nitrogen (N)

Crucial for tissue protein synthesis and production of nitrogenous compounds.
Involved in various functions including hormones, immune mediators, neurotransmitters, and antioxidants.

Magnesium (Mg)

Supports muscle and nerve function, blood pressure regulation, and immune system health.

Phosphorus (P)

Vital for growth, maintenance, and repair of tissues and cells.
Essential for DNA and RNA production.
Helps balance and utilize vitamins and minerals like vitamin D, iodine, magnesium, and zinc.

Sulphur (S)

Third most abundant element in the body, following calcium and phosphorus.
Key component of amino acids, particularly methionine and cysteine.
Aids in bacterial resistance, blood cleansing, and cell protection.

Chloride (Cl)

Regulates fluid balance and nutrient movement in and out of cells.
Maintains proper pH levels and stimulates stomach acid for digestion.
Facilitates oxygen and carbon dioxide flow within cells and supports nerve and muscle activity.

Potassium (K)

Facilitates nerve stimulation response and muscle contraction, including cardiac muscles.
Reduces sodium's impact on blood pressure.
Aids nutrient uptake by cells and removal of waste products.

Calcium (Ca)

Most abundant mineral in the body, essential for strong bones and teeth.
Plays a critical role in numerous bodily functions.

Iron (Fe)

Necessary for growth and development, aiding in hemoglobin and myoglobin production.
Hemoglobin carries oxygen in red blood cells; myoglobin supplies oxygen to muscles.
Important for hormone production as well.

Zinc (Zn)

Supports immune system function, metabolism, wound healing, and sensory perception (taste and smell).
Generally obtained through a varied diet including chicken, red meat, and fortified cereals.

Iodine (I)

Necessary mineral for synthesizing thyroid hormones that regulate metabolism.
Essential for bone and brain development, particularly during pregnancy and infancy.
