[Experimental studies concerning the metabolism, the nutriture, and the requirement for vitamin B6 in childhood (author's transl)].

The study presented gives details about vitamin B6 metabolism in infancy and childhood. After a short review about the history of vitamin B6, some details are given about the chemical structure, the metabolism, and the functions of vitamin B6. The description of some modern methods for the determination of vitamin B6 follows. The experimental part describes the relationship between vitamin B6 nutriture of the pregnant woman and the B6 status of her newborn infant. Then some studies about the vitamin B6 nutriture of the preterm and the full term infant follow, giving some details about the maturation time of enzymes in vitamin B6 metabolism itself. The last chapter deals with the vitamin B6 deficiency syndromes in infancy and childhood. The relations between vitamin B6 and iron deficiency anemia on the one hand and vitamin B6 and celiac disease on the other hand represent some other new investigations in this field.
