Abstract
Published data from chemical analyses of human fetuses were utilized to construct a reference fetus of representative body composition. For gestational ages 20-40 wk body composition of the reference fetus is presented, including water, lipid, protein and major minerals. Concentrations of water, Na and Cl per unit of body weight decreased with increasing gestational age, whereas those of protein, lipid, C, P, Mg and K increased. From the estimates of body composition at each age and from the gain in body weight, composition of gain and daily increments of body components were calculated.
