Pantothenic acid, also known as Calpan or Vitamin B5, plays a very important role in the metabolism of carbohydrates, fats, and amino acids through its presence as the prosthetic group of Coenzyme A (CoA). CoA derivatives are involved in the synthesis of triglycerides and phospholipids. D-calcium pantothenate is the common source used to supply pantothenic acid in the livestock, poultry, and aquafeed market. The most important processes in the body that require Vitamin B5 include: – its role in enzymes involved in cellular metabolism and energy production – its role in optimal nervous system function – its role in antibody production and proper immune function. Calpan is a product of Hwatson (China) and has a purity of 98%.
