Product Application of Palmitic Acid CAS#57-10-3
Palmitic acid is a naturally occurring fatty acid widely present in plants and animals. In the human body, excess carbohydrates can be converted into palmitic acid, making it the primary fatty acid formed during fatty acid biosynthesis and an important precursor for the production of longer-chain fatty acids.
