|
Thamine(B1)
|
First B vitamin to be identified
Widely available:pork, legumes, whole grain, nuts seeds deficency: bari bari-effects moral, and warnike-korsakoff syndrome in alcoholics. No toxicity |
|
Riboflavin(B2)
|
Sources:milk,green veggies, whole grains.
Easily destroyed by UV light,that is why milk is in opaque cartons. Co-enzyme-energy release from all nutrients(CA cycle), and helps with vitamin absorbtion deficiency:inflammation of membranes especially eyes and mouth |
|
Niacin
|
Body can make it from tryptophan.
Deficency: mostly slave pop, pellagra-4D's: dermititous, diahria, dementa, death. Toxicity: overuse of supplements, niacin flush: painful dialation of cappillaries, vomiting, diarrhea. Source:meat, poultry, fish, legumes, grains other than corn coenzyme in energy transfer-lower cholesterol, functions in glucose and fatty acid metabolism |
|
Biotin
|
Coenzyme that carries CO2 in TCA cycle
Deficiency: rare-can be induced by raw egg whites which have avidin and causes nausea, hair loss, lethary. Source: egg yolks, and a variety. Toxicity: none reported cooking denatures avidin |
|
Folate
|
helps activate B12
coemzyme assists DNA synthesis and cell growth-prevents nueral tube defects in babies: spina bifia (split or open spine), anecephaly (fatal lack of brain) deficiency: metablastic anemia(large immature RBC, O2 deficency) sources: leafy green veggies, legumes, oranges, and fortified grains. 5 fruits/veggies a day prevents def. |
|
B6
|
Coenzyme in amino acid metabolism, hemoglobin and DNA
toxicity: only with supplements, causes neurological damage Deficiency: depression and confusion-hastened by high protein diet making needs more Source: meat, fish, poultry, veggies, and fruits |
|
Panothenic Acid
|
part of coenzyme A-cross roads compound in metabolic pathways.
deficiency: rare-involves failure of all systems. relative nontoxic |
|
vitamin b12
|
amino acid metabolism, DNA synthesis, folate activation and nerve sheath maintanance.
Deficiency: poor absorption or lack of intrinsic factor(atrophic gastritis is common after 60 & b12 remains attached to food & not ablsorbed) Pernicious anemia-large immature RBC, muscle weakness, nero damage. controversy-folate can cure blood symptoms, but not nerve damage. source-animal products and fortified grains |
