Brain development and assessing the supply of polyunsaturated fatty acid.

Membrane lipids are necessary for structure and function of the developing nervous system. Rapid synthesis of brain tissue occurs during the last trimester of development of the human brain and the early postnatal weeks. This synthesis of brain structure involves the formation of complex lipids, many of which contain significant quantities of chain-elongated desaturated homologs of essential fatty acids. The present report discusses the implications of change in nutritional status on processes of brain development and metabolic events that involve lipids.
