Study Notes
Vitamin B2 (Riboflavin)
- Active forms include Flavin mononucleotide (FMN) and Flavin adenine dinucleotide (FAD).
- Acts as co-enzymes in hydrogen transfer processes.
- Deficiency leads to seborrheic dermatitis, a skin condition.
Vitamin B3 (Nicotinic Acid or Pellagra)
- Formed from the amino acid tryptophan in the body.
- Active co-enzymes are Nicotinamide adenine dinucleotide (NAD) and Nicotinamide adenine dinucleotide phosphate (NADP).
- Pellagra manifests as dermatitis, diarrhea, and dementia, often affecting those consuming maize flour lacking tryptophan and nicotinic acid.
- Symptoms can include burning sensations in the feet.
Vitamin B6 (Pyridoxine)
- Active form of vitamin B6 is Pyridoxal phosphate (PLP).
- PLP is crucial for numerous biochemical reactions in the body.
Folic Acid (Vitamin B9)
- Active form is Tetrahydrofolate (FH4).
- Essential for red blood cell formation and various metabolic processes.
Vitamin B12 (Cobalamins - Anti-pernicious Anemia Factor)
- Functions include aiding in the construction of genetic material (nucleic acids).
- Supports the development of normal red blood cells.
- Essential for the maintenance and health of the nervous system.
