[Fatty-acid pattern of serum lipids (standards for mothers, placentas and infants)].

The standard distribution of the fatty acids in the total lipids of serum was gaschromatographically defined in the respective umbilical cord blood of 24 mothers and their newborn babies, as well as in 20 placentas. The same examinations were made with 30 newborn babies on the day of birth, 14 children in the newborn stage, 22 young babies between 3 and 10 weeks old and 16 older babies between 4 and 12 months old. In the umbilical cord mixed blood of another collective (n = 10) the separation of the total serum lipids in the individual fatty fractions (neutral lipids, phospholipids, cholesterol esters) was also undertaken. The results were compared and existing differences were discussed. It was further established that an advance towards the adult's fatty acid pattern already takes place at an age between 4 and 12 months.
