Week 9 and 10 Flashcards
Name the water-soluble vitamins
B1: Thiamin B2: Riboflavin B3: Niacin B5: Pantothenic acid B6: Pyridoxine B7: Biotin B9: Folate B12: Cobalamin Choline Vitamin C Ascorbic acid
B1: thiamin coenzyme
TPP
B1: thiamin Deficiency
Berri Beri
Wernicke-korakoff Syndrome
B1: thiamin function
- coenzyme in carbohydrate metabolism and energy release
- decarboxylation reactions
B1: thiamin absorption
- In Small intestine
- Via sodium-dependent active or passive absorption
B1: thiamin Transport
Transported by red blood cells as TPP
B1: thiamin converted to the active form by
adding two phosphate groups
B1: thiamin rich food source
Meat
B2: Riboflavin coenzyme
FMN and FAD
B2: Riboflavin Deficiency
Glossitis
- inflammation of mouth and tongue
Angular stomatitis
-cracks corner of the mouth
B2: Riboflavin function
co-enzyme in numerous oxidation-reduction reactions including those of energy release
B2: Riboflavin absorption
HCl in the stomach releases B2 bound to dietary compounds
free riboflavin absorbed via active transport or diffusion depending on the concentration
B2: Riboflavin transport
via protein carriers in the blood
B2: Riboflavin rich food source
dairy milk products
B3: Niacin coenzyme
NAD/ NADP
B3: Niacin Deficiency
Pellagra
- 4D’s
- dermatitis, diarrhea, demintia and death
- red rash
B3: Niacin function
coenzyme in numerous oxidation-reduction reaction in energy metabolism, synthesis, and breakdown of fatty acids
B3: Niacin toxicity
from fortified foods only: leads to flushing of the skin
B3: Niacin absorption
in the stomach but mainly small intestines via active transport and passive diffusion depending on the concentration available
B3: Niacin food source
Chicken
