vitamin A

fat-soluable vitamin
Retinol, Beta-Carotene
function: imp. for pigment of rods in retina. rods enable us to seen in dim light. a lack of vit. A will cause night blindness. long-term vit. A deficency will cause blindness.
--protects against cancer of skin, and other epithelial cells in respiratory tract, GI tract, urinary bladder, and breast.

--vit. A is an antioxidant, attaching to dangerous free radicals

also necessary for proper bone growth renal function, digestive activity, and normal reproductive function in both sexes.

SOURCES: dairy, liver, fish, yellow and green fruits and vegetables

OD: nausea, vomiting, diarrhea, HA, skin peeling, anorexia, irritability, wasting of bone mass, and in fatal cases destruction of the liver.

vitamin A is teratogenic when taken in large doses by pregnant mothers in the first 3 months of pregnancy
vitamin B1

water-soluable vitamin
Thiamine (coenzyme)

function: enables proper carbohydrate metabolism. also plays roll in well-being of the nervous or cardiovascular system

deficency: causes beriberi. beriberi symptoms include wasting of muscles, and malfunctioning of the nervous system. other signs of deficency include anorexia constipation, nausea, mental confusion and depression

sources: grains, cereals, beans, pork, liver
vitamin B2

water-soluable vitamin
Riboflavin

function: important component for proper enzymatic activity in metabolism of carbohydrates and its production of energy for the body. necessary for proper growth and maintenance of the body

deficency: can cause anemia and affect the nervous system and cause depression. the tounge, mouth, eyes, and skin may become dried out or sore. HA, burning of the skin (especially the feet), cracking of the corners of the mouth, and seborrheic dermatitis.

sources: cereals, eggs, dark green vegetables, milk, liver
>>may turn urine yellow to orange

function: used in tissue respiration and metabolism.

nicotinic acid has been found to lower LDL (bad) cholesterol. it releases histamine and causes periphial vasodialation.

necessary for lipid metabolism, proper nerve functioning, and overall maintenace of cells

Panthothenic acid (coenzyme)

function: affects body metabolism. it is incorperated into a coenzyme or the enzyme itself to synthesize important compounds in the body such as fatty acids, steroid hormones, and other molecules necessary for protein and carbohydrate metabolic processes.

produced by bacteria within the GI tract of many animals, and is also in plant cells

deficency: HA, sleep disturbances, muscle cramps, and fatigue.

sources: vegetables, cereals, yeast, liver
vitamin B6

water-soluable vitamin
Pyridoxine

function: functions in the metabolism of carbohydrates, proteins, and fats in the diet. because it aids in metabolism this is why it is added to foods. greater metabolism means that carbs are not absorbed by the body

it aids in the absorption of B12. and is a component needed for the production of many different amino acids, inlcuding a major amino acid neurotransmitter found in the brain and spinal cord

deficency: skin problems such as seborrheic type lesions, stomatitis and even seizures. can cause dwarfism, blindness, dementia, depression and osteoporosis.

meat, liver, chicken, salmon, trout, beans, rice, whole grains

function: essential vitamin for DNA synthesis and creation of cells in areas that have high growth turnover. thse are bone marrow and GI tract.

sources: green vegables, beets, OJ, and liver

deficency: diarrhea, weight loss, weakness, sore mouth, irritability, and behavior disorders. interactions may occur with phenytoin, estrogen, or nitrofurantoin

sources: green vegetables and liver
vitamin B12

water-soluable vitamin
Cyanocobalamin (coenzyme)

function: required by the body for red blood cell production, myelin sheath production, and the synthesis of neucleic acids.

deficency: anemia, dementia, depression, hair loss, poor growth rate in children, and anorexia.

pernicious= severe anemia, unspecific to any cell type
megaloblastic= red blood cells are abnormally formed

sources: meats, liver, chicken, dairy products
vitamin C

water-soluable vitamin
Ascorbic Acid

function: anti-oxidant, formation of connective tissue found in bones, teeth, and gums. aids in wound healing. aids in proper nutrition of cells and their permeability

deficency: causes scurvy=excessive bleeding in the skin and gums, causing teeth to become loose. reduction in body's ability to produce T cells
vitamin D2

fat-soluable vitamin
Ergocalciferol

result of UV radiation on a yeast product found in bread and milk. this gets injested, transported to the liver, and then the hormone calciferol is formed. calciferol is then transported to the kidneys where calcitriol (aka vit D hormone is produced).

vit D hormone increases P absorption and Ca intake. necessary for providing adequate CA and P to mother and child during preg. and breast-feeding.

sources: dairy, eggs, natural light, and artificial light containing UV

deficiency: causes rickets in children=bone weakness and deformities and causes osteomalacia in adults. osteomalacia in adults also causes osteoporosis

OD: hypercalcemia, calcium deposits in various areas of the body such as soft tissue and joints, causing muscle weakness or pain. convulsions or death may occur in serious cases
vitamin D3

fat-soluable vitamin
Cholecalciferol

produced by the skin in presence of UV light

vit D hormone increases P absorption and Ca intake. necessary for providing adequate CA and P to mother and child during preg. and breast-feeding.

sources: dairy, eggs, natural light, and artificial light containing UV

deficiency: causes rickets in children=bone weakness and deformities and causes osteomalacia in adults. osteomalacia in adults also causes osteoporosis

OD: hypercalcemia, calcium deposits in various areas of the body such as soft tissue and joints, causing muscle weakness or pain. convulsions or death may occur in serious cases
vitamin E

fat-soluable vitamin
Alpha-tocopherol

potent anti-oxidant, essential for normal metabolism and protection of the skin, eyes, tissues, and muscles. protects red blood cells from damage

source: whole grains, nuts, corn, vegetables, eggs, and butter

deficency: anemia and cardiovascular disease
vitamin K

fat-soluable vitamin
Phytonadione

responsible for the formation of blood coagulation factors

sources: found in wheat, legumes, egg yolks, milk, and vegetables such as broccoli and spiniach. certain bacteria in the intestine also produce vitamin K as a byproduct of their metabolism.

deficency: cause an increased tendency to bleed. the bleeding may be repeated nosebleeds, blood in the sputum w/o coughing, spontanious bruising in several parts of the body, or blood in the urine
