Individual minerals
CALCIUM AND PHOSPHORUS
Calcium is the most common mineral in the body and phosphorus is the next most common. Calcium and phosphorus serve as structural components of the bones and the teeth.
Calcium is also important as a messenger which mediates the following:
constriction and dilation of blood vessels
nerve impulse transmission
muscle contractions
secretion of hormones
blood coagulation
a co-factor for enzymes
Since calcium participates in so many functions including keeping the heart beating, it is essential to keep the blood level of calcium at a steady level. This explains why, even when the food is quite deficient in calcium it is not reflected in the blood levels. Additional calcium is quickly released from the bones when the levels in the blood drop below a certain point to ensure that enough calcium is present to keep vital functions working.
SODIUM, POTASSIUM AND CHLORIDE
Sodium, potassium and chloride are the major electrolytes in the body water.
Interesting fact
Electrolytes are minerals found naturally in the body that are present as electrically charged particles, or ions. Electrolytes are needed to keep the body's balance of fluids at the proper level.
They are involved in:
maintaining acid-base balance
maintaining osmotic balance
transmitting nerve impulses
facilitating and transmitting muscle contractions
Many cat foods sold in grocery stores have a very high salt content.
MAGNESIUM
is a component of bone, enzymes and intracellular fluids
has influence on neuromuscular transmissions
IRON
Is an essential component of:
haemoglobin: the oxygen carrying pigment of the blood
myoglobin: the oxygen carrying pigment of the muscles
ZINC
Zinc is a constituent or activator of more than 200 enzymes, so it is involved in a high number of diverse physiological functions. Some of zinc's primary functions include:
immunocompetence
skin and wound healing
growth
reproduction
COPPER
Copper is needed for:
the formation of red blood cells
normal pigmentation of skin and hair
SELENIUM
Is an essential component of the naturally occurring antioxidant, gluthathione peroxidase, which is present in all body cells.
