Calcium and sodium pantothenate can be chromatographed following derivatiza-tion, degradation, or a combination of the two. Derivatization is mostly based on the determination of the corresponding acetates or trimethylsilyl ethers. The determination of pantothenic acid and/or pantothenates as acetates (72) requires esterification of the carboxyl group prior to acetylation of the hydroxyl function. [Pg.587]

Vitamin B5 occurs in three biologically active forms in foods [1] pantothenic acid, coenzyme A (CoA), and acyl carrier protein (ACP). Calcium or sodium pantothenate are the forms generally used as supplements in infant formula [4], The total quantification of vitamin B5 requires the release of pantothenic acid from CoA and ACR Since it consists of pantoic acid linked through an amide linkage to p-alanine, chemical hydrolysis cannot be used. The only alternative to free pantothenic acid from CoA is the digestion with a number of enzymes (pepsin, alkaline phosphatase, pantetheinase) nevertheless, this treatment is unable to release the vitamin from ACP [27,28]. For the extraction of free pantothenic acid from milk and calcium pantothenate from infant formula an acidic deproteination is often used, followed by centrifugation and filtration [29,30]. [Pg.484]
