Vitamin B1 Thiamin
Properties of Vitamin Not stored in body in large quantities (30-
B1 70 mg); easily destroyed by heat or
oxidation
Foods that destroy tea, raw fish, clams, shrimp, mussels, fish
thiamin paste, betel nut, and fermented tea because
they contain thaminase
Coenzyme for thiamin pyrophoshate (TPP)
thiamin
carbohydrate metabolism (TCA cycle);
Functions of Thiamin maintenance of nervous system;
affects cardiovasular system (weak
muscle, heart failure); normal appetite
(occurs >0.2 mg/1000 calories)
Thiamin Deficiency neuritis (paresthesia), irritability, mental
depression, anorexia

Takaki cured Japanese navy: less rice &
Beri Beri more vegetables; Eijkman fed pigeons
same diet as prisoners; Grijns suggested
rice have vital substance in hulls; Funk
isolated
and named it vital amine
Beri Beri (cont) 1.5 million suffer symptoms in countries
where polished rice is a staple because
failure to enrich rice, washing of rice,
soaking of rice
Infantile: Cyanosis, tachycardia, weak cry,
convulsions; 2-5 months, frequently fatal;
Types of Beri Beri often breastfed mothers with low
thiamin diet
Adult: Wet (edematous) - swelling of
limbs, accumulation of fluid in heart leads
to heart failure; Dry (wasting) - gradual
loss of body tissue
Mental confusion: irritability, depression,
headache, fear, coma
Symptoms of Beri Beri Neurological changes: muscle weakness
and wasting, CNS creates unsteady gait,
peripheral neuritis, decreased speed and
coordination (loss of knee/ankle jerk),

1 mg for any caloric intake)
Males: 1.2 mg; Females: 1.1
Thiamin RDA mg
Requirements Increases with pregnancy, growth, old
age (absorption problems), alcohol
(thiamin necessary to breakdown to
acetaldehyde & interferes with
thiamin absorption)
Decreases with high fat diet (means low
carbohydrates - need thiamin for
metabolism)
Toxicity of Thiamin None Known
Food Sources of pork products, whole grains, and enriched foods
Thiamin
Vitamin B2 Riboflavin
Properties of riboflavin yellow-green luminescence, heat stable,
unstable to alkali & light
Functions of Riboflavin carbohydrate, fat, & energy metabolism;
