- Function:
- TPP acts as a coenzyme in oxidative decarboxylation reactions in carbohydrate metabolism.
- Crucial for nerve conduction.
- Deficiency (Beriberi):
- Reduced TPP levels
- Impaired carbohydrate metabolism
- Decreased energy production
- Impaired nervous system function
- Two types:
- Dry Beriberi: Peripheral neuritis, indigestion, constipation, muscle wasting, and hyperesthesia
- Wet Beriberi: Heart failure, edema
Vitamin B2 (Riboflavin)
- Active forms: Flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD)
- Function:
- FMN and FAD act as coenzymes in oxidation-reduction reactions, specifically carrying hydrogen in carbohydrate and protein metabolism.
- Deficiency:
- Not life-threatening
- Characterized by:
- Ocular disturbance
- Cheilosis
- Glossitis
- Photophobia
- Vascularization of the cornea
