Abstract
The fatty acid components of cobostruin collected from seventeen normal Lebanese women on the day before delivery and on the three successive days were determined. The laurie and myristic acid contents of the first two days’ collection of cobostrum were relatively small compared with mature milk, but rapidly increased after the second day. The increase in laurie and myristic acids was compensated for by a decrease in the C18 acids. The level of palmitoleic acid increased at approximately the same rate as that of mynistic acid. It is concluded that almost all the fatty acid components of early cobostrum are derived from extrainaininary fatty acids.
