Buy Vitamin B5

Contents: 1000 gr Pantothenic acid (vitamin B5)

Vitamin B5, also known as pantothenic acid, is found in a variety of foods, both animal and plant-based. Here are some examples of foods that are good sources of vitamin B5:

  1. Meat: Beef, chicken, turkey, pork, and organ meats like liver are rich sources of vitamin B5.
  2. Fish: Salmon, trout, tuna, mackerel, and other fatty fish contain significant amounts of vitamin B5.
  3. Dairy Products: Milk, yogurt, cheese, and other dairy products are good sources of vitamin B5.
  4. Eggs: Eggs, particularly the yolks, contain vitamin B5.
  5. Whole Grains: Whole grains like brown rice, oats, barley, and wheat are rich in vitamin B5.
  6. Legumes: Lentils, chickpeas, black beans, kidney beans, and other legumes are good sources of vitamin B5.
  7. Nuts and Seeds: Sunflower seeds, peanuts, almonds, and hazelnuts are examples of nuts and seeds that contain vitamin B5.
  8. Vegetables: Avocado, broccoli, sweet potatoes, corn, mushrooms, and cauliflower are some vegetables that provide vitamin B5.
  9. Fruits: Fruits like avocado, strawberries, oranges, and bananas contain modest amounts of vitamin B5.
  10. Fortified Foods: Some breakfast cereals and other processed foods may be fortified with vitamin B5.

Including a variety of these foods in your diet can help ensure an adequate intake of vitamin B5.

Vitamin B5, also known as pantothenic acid, is a water-soluble vitamin that is part of the B-vitamin complex. It plays a crucial role in the synthesis and metabolism of carbohydrates, proteins, and fats. Pantothenic acid is a component of coenzyme A (CoA), which is essential for numerous biochemical reactions, including the production of energy from carbohydrates, fatty acid synthesis, and the synthesis of cholesterol and steroid hormones.

Vitamin B5 is found in a variety of foods, including meat, poultry, fish, whole grains, legumes, eggs, dairy products, and some vegetables and fruits. Additionally, it is widely available as a dietary supplement.

A deficiency in vitamin B5 is rare since it is present in many foods, but it can occur in cases of severe malnutrition or in individuals with certain medical conditions. Symptoms of deficiency may include fatigue, irritability, gastrointestinal disturbances, and neurological symptoms.

Overall, vitamin B5 plays a vital role in maintaining overall health and is involved in numerous physiological processes within the body.

Vitamin B5 supplement

Vitamin B5, also known as pantothenic acid, can be synthesized by plants, bacteria, and fungi. The primary pathway for its biosynthesis involves several enzymatic steps. Here's a simplified overview of the process:

  1. The initial step in pantothenic acid biosynthesis is the condensation of pantoate and β-alanine. Pantoate is derived from α-ketoisovalerate, an intermediate in the biosynthesis of valine, while β-alanine is formed from aspartate.
  2. The condensation reaction is catalyzed by the enzyme 2-dehydropantoate 2-reductase, also known as ketopantoate reductase (KPR), forming 2-dehydropantoate.
  3. Next, 2-dehydropantoate undergoes a reduction reaction to form 2,4-dihydroxy-3,3-dimethylbutanoate, catalyzed by the enzyme 2-dehydropantoate 4-reductase (DPAR).
  4. The final step involves phosphorylation of 2,4-dihydroxy-3,3-dimethylbutanoate to produce pantothenate (vitamin B5). This reaction is catalyzed by the enzyme pantothenate kinase.

In microorganisms such as Escherichia coli, the genes responsible for encoding the enzymes involved in pantothenic acid biosynthesis are organized into an operon known as the pan operon. The expression of these genes is regulated by various factors, including the availability of precursor molecules and the need for pantothenic acid.

While plants, bacteria, and fungi can synthesize pantothenic acid de novo, animals, including humans, cannot produce it and must obtain it from their diet or from supplements.

Excellent produit, au goût moins amer que d'autres poudres b5 mais aussi efficace.
