The relationships between essential fatty acid (EFA) composition of
colostrum and white adipose tissue (WAT) were examined on day 5 after
delivery in 69 healthy women. Fatty acid composition was assessed
by capillary gas chromatography, and 33 fatty acids were detected
in colostrum and in WAT. Total polyunsaturated fatty acid (PUFA) content
was similar in colostrum and in WAT (15.7 +/- 3.1% and 16.1 +/- 3.8%,
respectively), but long-chain PUFA content was higher in colostrum
than in WAT (2.9 +/- 0.6% and 1 +/- 0.2%, respectively; P less than
0.001). The concentrations of linoleic acid were significantly correlated
between colostrum and WAT (r = 0.77, P less than 0.0001). No correlation
was found for alpha-linolenic acid. The relationships between long-chain
PUFA composition of colostrum and WAT suggested that individual factors
along with tissue specificity of the mammary gland are involved in
either the capacity of desaturating and chain- elongating pathways
and/or incorporation of long-chain PUFAs into colostrum.
