General Grouped Questions Flashcards
Which vitamin does not have specific or sensitive biomarkers?
choline
Name the vitamins
thiamin (b1), riboflavin (b2), niacin (b3), biotin, folate, b6(PLP), b12, panthothenic acid(coa, acyl carrier protein), vit c, vit E, and choline(acetycholine, sphingomyelin)
Name vitamin active forms.
thiamin -- TDP, TPP Riboflavin -- FMN, FAD niacin -- NAD, NADP biotin -- biotin pantothenic acid -- CoA, acyl carrier protein folate -- methyl-THF b12 -- b12 b6 -- PLP Vit C-vit C vit E -- vit E cholin -- acetycholine, sphingomyelin, betaine
the ones who no diff name are biotin, b12, b6, vit c, vit E
what vitamins are involved in the methionine synthase pathway?
riboflavin, folate, choline (as betaine), B6, B12
Which vitamin is needed to synthesize another vitamin?
riboflavin (B2) is needed for B6
NAD(niacin) synthesis requires which two vitamins?
riboflavin (B2) and thiamin(b1); deficiency of one starts secondary another.
What are the water soluble vitamins?
thiamin, riboflavin, niacin, biotin, panthothenic acid, folate, b12,b6, vit c and FREE choline
what food source do most (not vit c) vitamins have in common?
milk, eggs. vit C and E mostly from plant sources.
what vitamins are not found in both plant and animal sources?
B12–animal
folate–mostly plants and yeast and grain
Vit C –primarily fruits,veggies, citrus, green peppers
Vit E – plants, canola and wheat germ oil, corn oil, cashews
Which vitamins are susceptible to destruction and how?
Thiaminases in nardoo ferns and some raw fish destroy thiamin
Avidin in raw egg whites destroys biotin
Thiamin is heat-sensitive
Nixtamalization treatment releases tryptophan, a niacin-equivalent
Riboflavin is light-sensitive
Pyridoxine & niacin are heat-stable(b6,b2)
