Vitamins and Minerals Flashcards
What is the function of Sodium (Na) as a macromineral?
Is it more concentrated in or out of the cell?
Sodium (Na) functions in the rising phase of action potential of nerve and skeletal muscle.
Its concentration is higher in the extracellular fluid.
What is the function of Potassium (K) as a macromineral?
Is it more concentrated in or out of the cell?
Potassium (K) functions in the falling phase of action potential of nerve and skeletal muscle.
Its concentration is higher in the intracellular fluid.
What is the function of Calcium (Ca) as a macromineral?
Is it more concentrated in or out of the cell?
Calcium (Ca) is necessary for muscle contraction, is a constituent of bone, and allows release of neurotransmitters at the presynaptic terminal.
Its concentration is higher in the extracellular fluid.
What is the function of Magnesium (Mg) as a macromineral?
Is it more concentrated in or out of the cell?
Magnesium (Mg) is located in the NMDA and AMPA receptor to modulate the entry of calcium and sodium into the post synaptic neuron. It’s also a cofactor for Kinases.
Its concentration is higher in the intracellular fluid.
What doses are needed for macrominerals?
Gram doses
What is the the function of Chromium (Cr) as a micromineral?
Chromium (Cr) is a Glucose Tolerance Factor that helps insulin bind to the cell.
What enzymes is Copper (Cu) a cofactor for?
Where are these enzymes found?
Copper (Cu) is a cofactor for Copper-Zinc Super Oxide Dismutase found in the cytoplasm, and for cytochrome c oxidase found in Complex IV in ETC.
What is the function of Fluoride (F) as a micromineral?
What else should you know about Fluoride (F)?
Fluoride (F) increases hardness of enamel of teeth.
You should know that high levels of Fluoride (F) are toxic.
What is Iodine (I) a cofactor for?
Describe what these chemicals are made of.
Iodine (I) is a part of Thyroxine T4, 2 tyrosine + 4 iodine, and part of Triiodothyronine, 2 tyrosine + 3 iodine.
Where is Iron (Fe) found?
What does Iron (Fe) deficiency lead to?
Iron (Fe) is found in cytochromes, hemoglobin, and myoglobin.
Iron (Fe) deficiency leads to microcytic anemia.
What enzymes is Manganese (Mn) a cofactor for?
Where are these enzymes found?
Manganese (Mn) is a cofactor for Mn Super Oxide Dismutase and Decarboxylase.
Both enzymes are found in the mitochondria.
What enzyme is Molybdenum (Mo) a cofactor for?
What does this enzyme do?
Molybdenum (Mo) is a cofactor for Xanthine Oxidase.
Xanthine Oxidase breaks down purines.
What enzyme is Selenium (Se) a cofactor for?
What else should you know about Selenium (Se)?
Selenium is a cofactor for Glutathione Peroxidase.
You should know that Selenium (Se) is deficient in soil today.
What enzymes is Zinc (Zn) a cofactor for?
What does Zinc (Zn) deficiency cause?
Zinc (Zn) is a cofactor for Cu-Zn SOD (located in the cytoplasm) and Carbonic Anhydrase (located in red blood cells).
Zinc (Zn) deficiency causes white lines on nails and poor wound healing.
What doses are needed for microminerals?
All microminerals are needed at microgram amounts. They are toxic at higher levels.
