The methods of the measurement of free form and bound form pantothenic acid (PaA) were studied and PaA in blood and urine of the children in each age was measured. The bacteriological method of Skeggs-Wright using Lactobacillus arabinosus was applied to measure PaA. The decomposition of bound form was carried out according to the method reported by Novelli et al.. The following results were obtained on the studies of PaA metabolism in childhood. The total PaA existed in extremely high level in cord blood and new born baby's blood, and decreased with ages. The free type PaA was also in higher level in the children of younger age. The level of PaA in urine was also measured in the children with age 4 to 16. The average value in 24 hours urine was calculated to be 1.8〜3.0 mg which was lower compared with the average value of 2.6〜5.7 mg obtained from the data of the adult.
