MINERAL WATA Flashcards
they increase insulin receptor-mediated signaling
chromium
this mineral mediates deiodination of thyroxine to triodothyronine
selenium
functions of this mineral is to maintain fluid and cell integrity, acid-base balance and the conduction of cardiac muscle and nerve impulses
potassium
responsible for antagonizing the effect of Ca++ in CNS and CVS
Mg
calcium absorption is hindered by
oxalic acid
mineral involved in protein metabolism and oxidation reactions
molybdenum
mineral deficiency may result into impaired growth and development, skin lesions and loss of appetite
zinc
is osmoregulation a function of iron
oh hell naw
mineral that is considered important in maintaining electrical potential in nerves and membranes is
magnesium
mineral necessary for the clotting of blood. functions of certain enzymes and control of fluids through cell membranes
calcium
normal glucose metabolism requires
chromium/zinc
alcohol dehydrogenase from liver contains
zinc (PTCLAAS)
mitochondrial superoxide dismutase contains
zinc, copper, manganese, selenium
the deficiency of copper decreases the activity of the enzyme
lysine oxidase (FSLTCH)
mitochondrial pyruvate carboxylase contains
manganase
iron transport is mainly regulated by
hepcidin
the mineral deficient in keshans disease is known to be a cofactor of this enzyme
iodothyroninedeiodinase
mineral required as a constituent of B12
cobalt
molybdenum, copper and nickel are
essential cation trace elements
is molybdenum-xanthine oxidase correctly paired
yes
zinc level in the prostate gland is said to be preventive of prostate cancer because it
stimulates expression of BAX gene that increases caspase cascade
an endemic disease of cardiomyopathy in children is attributed to which mineral
low Se in the environment
cofactor in melanin production
copper
enzyme-controlled energy yielding reactions of metabolism
phosphorus
utilization of iron and in hemoglobin synthesis
copper
wilsons disease is an example of copper
toxicity
menkes syndrome is an example of copper
deficiency
antioxidant property is seen where
Zn,Cu,Mg(superoxide dismutase) and selenium(glutathione peroxidase)
metallothionein is a binding protein both for
zinc and copper
increase in zinc decreases ____ in order for estrogen conversion to decrease
aromatase
HFE GENE is located in chromosome
6
most numerous cation
calcium
most numerous anion
phosphorus
most numerous essential trace element
iron
contains FERRIC REDUCTASE
Duodenal cytochrome B
master regulator of iron
hepcidin
contains the eznyme ferrous oxide
hephaestin
what downregulates ferroportin
hepcidin
what will increase your hepcidin
lipopolysaccharides, inflammatory mediators, increase ferrous in blood, hemochromatosis gene
(LPS,IL-6, increase Fe++ and HFE gene)
what will happen to iron in the blood if hepcidin is high
decreased of iron
decreased ferroportin
low iron level in blood
movement into zincosomes
ZNT
movement out of plasma
ZNT
major signaling molecules to boost immune system
kinases, protein phosphatases, transcription factors
Mn-superoxide dismutase is found
in the mitochondrial matrix
treatment for copper toxicity(wilsons)
penicillamine
