Extract: The total lipid content and fatty acid composition of preterm human colostrum and mik were analyzed from aliquots of 24-h collections of colostrum, transitional milk, and mature milk obtained from 21 women who had delivered premature infants with a mean birth weight of 1,049 and a mean gestational age of 29. The total lipid content increased significantly with time of lactation, from 1.99 g/dl in colostrum to 3.89 g/dl in mature milk. With respect to the fatty acid pattern, the percentages of 12:0 and 14:0 increased significantly while those of 16:0 and 18:1 decreased significantly with time of lactation. The percentages of 10:0, 16:1, 18:0, 18:2, and 18:3 did not vary significantly with the duration of lactation. Similar compositional changes have been described in term human colostrum and milk as the duration of lactation progresses. (author)
