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.
