[Human milk - variations in lactose, potassium, sodium and total lipid concentrations and in fatty acids composition of lactating women in early puerperium].

Some biochemical components were studied in the milk of 16 lactating women during the first six postpartum days. A gradual increase in the lactose and potassium concentration and a decrease in the sodium concentration were observed, as well as an increase in the total lipids concentration and a significant shifting in the fatty acids composition where the biosynthesis of the fatty acids with a lower number of C atoms (C 10:0, C12:0, C 14:0) at the expence of the fatty acids with higher C atoms number was intensified.
