Vitamin B5 - Pantothenic Acid Flashcards
Vitamin B5 - Pantothenic Acid
• Vitamin B5 (pantothenic acid) is required to make coenzyme A (CoA) the same CoA that forms acetyl CoA (needed for ATP production). In this active form it is involved in hundreds of different reactions.
Vitamin B5- Food Sources
- Richest food sources include shiitake mushrooms, avocados, nuts, seeds, fish and meat. However, it is found widely distributed in almost all foods hence the name.
- Synthesised by intestinal bacteria, but to as yet unknown level of absorption. Theoretically, antibiotics may reduce synthesis
Vitamin B5 - Food prep
• Sensitive to processing, cooking and freezing with up to 80% loss.
