• activates folate
• maintains nerve cells
• helps metabolize some fatty acids and amino acids

part of coenzyme A used in energy metabolism

coenzyme in energy metabolism, fatty acids synthesis, amino acid metabolism, and glycogen formation

• collagen synthesis
• antioxidant
• promotes iron absorption
• involved in the metabolism of certain amino acids
• thyroxin synthesis
• immune system functioning
