Abstract
The gross chemical composition was determined in placentas of normal preterm, term, and intrauterine growth–retarded infants. In the placentas of the three groups of infants, there were no significant differences in the concentration of water or in the concentrations of collagen or ash. The protein concentration of the placentas in the intrauterine growth–retarded infants was significantly higher than that of the preterm and term infants. In the latter two groups, the concentrations of protein were approximately equal. The placental lipid content was significantly higher in preterm infants than in the other two groups. Placentas of the term and intrauterine growth–retarded infants contained approximately the same concentration of lipids.
