Functions Of Vitamin B5

  • Involved in the breakdown of carbohydrates and fats –Vitamin B5 helps in the breakdown of carbohydrates and fats to release energy.  
  • Involved in the biosynthesis of essential lipids, steroids, haemoglobin, and neuro-transmitters– Vitamin B5 is required in the synthesis of lipids (e.g., phospholipids, sphingolipids), steroids (e.g. growth and sex hormones), triglycerides (required for energy storage), cholesterol, and bile salts.
  • Synthesis of red blood cells-It is involved in the production of red blood cells.
