vitamins Flashcards
vitamins function like
drugs, not nutrients. Large doses of
niacin are used to lower cholesterol, low- density lipoprotein (LDL) cholesterol, and
triglycerides in people
with hyperlipidemia who do not respond
to diet and exercise.
Vitamins as Drugs
It consists of Vitamin A,
D, E, and K.
FAT-SOLUBLE
VITAMINS
It also functions as a primary fat
soluble antioxidant in the body,
protecting the polyunsaturated fats
and other lipids molecules.
Vitamin E
coenzyme essential for
the synthesis of prothrombin and at
least 6 of the other 13 proteins
needed for normal blood clotting.
Vitamin K
consists of Vitamin C and
the B Vitamins ( thiamin,
riboflavin, niacin, folate, B6,
b12, biotin, and pantothenic
acid)
WATER-SOLUBLE
VITAMINS
coenzyme in the
metabolism of carbohydrates and
branchedchain amino acids. In
Thiamin
an integral component of the coenzymes flavin adenine dinucleotide and flavin mononucleotide that function to release energy from nutrients in all
body cells.
Riboflavin
exists as nicotinic acid and
nicotinamide. The body converts nicotinic
acid to nicotinamide, which is the major form
of niacin in the blood. All protein foods
provide niacin, as do whole-grain and enriched
breads and fortifi ed ready-to-eat cereals.
Niacin
plays a role in the synthesis,
catabolism, and transport of amino acids and in
the conversion of tryptophan to niacin.
Vitamin B6
generic term for this B vitamin that
includes both synthetic folic acid found in
vitamin supplements and fortifi ed foods and
naturally occurring folate in foods such as green
leafy vegetables, legumes, seeds, liver, and
orange juice.
Folate
has an interdependent relationship with folate: each
vitamin must have the other to be activated.
is
involved in DNA synthesis and maturation of red
blood cells.
Vitamin B12
such as inositol
and carnitine, are sometimes
inaccurately referred to as B
vitamins because they are
coenzymes.
Non - B Vitamins
broad class of
nonnutritive compounds that
plants produce to protect
themselves against viruses,
bacteria, and fungi.
