Highlights from the Lipid Analysis Literature - 1998

The following references were collected as part of a weekly literature search that reflects my (former) personal research interests. However, most mainstream lipid analytical topics are covered. Among the exceptions are "steroidal hormones", "prostanoids", "fat-soluble vitamins" and "terpenoids", although some papers in these categories may be posted. My intention is to list only those papers that exhibit novel analytical methodology as opposed to tried and tested methods, although this may appear to introduce a bias towards modern mass spectrometry techniques. References are listed alphabetically by the first author.
