Quiz for trace minerals Flashcards
Component of enzymes that participate in energy production in mitochondoria
Iron
Important for oxygen carrying molecules (hemoglobin and myoglobin)
Iron
Heme iron
Animal protein
Non hem iron
Plants
Essential for citric acid cycle(Kreb cycle) enzime
iron
What will help iron absorption
Vitamin C and stomach acid
What will prevent iron absorption
Tannins( black tea)
Phytate (beans, seeds, tofu, etc)
Dietary fibre
Iron deficiency pathology
very common, due to menstration, pregnancy. Fetus requires more.
Iron deficiency anemia,fatigue, feeling cold,
Iron toxicity
liver failure, renal damage, significant mortality, hemachromatosis
non meat conversion factor
RDA values increase 90%, multiply by a factor of 1.8
Cofactor in a wide variety of enzyme, cellular signalling immune function
Zinc
heme production, energy metabolism, pancreatic hormones, and digestive enzymes, visual pigments in retina, endoctrine signalling
Zinc
immune booster
zinc
Why leavened breads make zinc more available?
yeast reduces phytate
Zinc deficiency phathology
diet high in phytate and malnourished
Phytate limits
iron and zinc absorption
zinc interfere with
copper and iron absorption, reduces HDL cholesterol, damages heart muscles
helps to build hemoglobin and collagen
Copper
enzyme help handle oxygen
Zinc
Go hand in hand with iron, help body to use iron efficiently
Zinc
important component of antioxidant enzyme
Zinc
Need for the function of superoxide dismutase and important enzyme for disposing free radicals
zinc (and Manganase)
Copper deficiency pathology
genetic disorder (menke's disease) Heavy iron or vitamin C supplementation interfere with copper absorption Zinc over dose
Copper toxicity pathology
Wilson’s disease - an uncommon genetic disorder where copper is not eliminated from the body
important part of enzyme that limit free radicals
Selenium (zinc and managanese)
Necessary for thyroid hormones synthesis
Selenium (and Iodine)
Important for the function of glutathione peroxicidase an antioxidant enzyme in the liver
Selenium
Cooperates with Vitamin E in eliminating free radicals
Selenium
where do you find selenium
soil
Meats, seeds and whole graines
Selenium deficiency
found in the area with low soil content
Sole purpose is for synthesis for thyroid hormone
Iodine
Where do you find iodine
Table salt, seafood daily product
Iodine deficiency
goitre
fetal death or severe mental retardation called cretinism
Iodine toxicty
death
Goitres (enlargement of the thyroid gland)
where do you find copper
organ meat
Chocolate
nuts and seeds, whole grains
interact with insulin to improve insulin function
Chronium (especially for type II diabetes)
Where do you find Chronium
liver nuts whole grains and stainless steel implements,
Dairy products and veggie are poor
associate with many enzyme
superoxide dismutase
Molybdenum (meats, daily, cereals legumes) and manganese (whole grains, nuts fruits and vegetables)
Manganese’s toxicity is from inhaled dust in mines
