Ken, Keith, and Mark~ Thanks for the good information. Ken, I hope you're feeling better! Below is the condensed version of what you taught me:
triglyceride = vegetable oil, three fatty acid tails bonded to one glycerol diglyceride = two fatty acid tails bonded to one glycerol monoglyceride = one fatty acid tail bonded to one glycerol free fatty acid = one fatty acid tail not bonded to anything ester = vegetable oil (triester of glycerol alcohol) or biodiesel (monoester of methyl or ethyl alcohol) transesterification = transformation of one type of ester into another type of ester (triglyceride into methyl ester) I really appreciate the collective brain trust this list embodies. ~leif Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Biofuels list archives: http://infoarchive.net/sgroup/biofuel/ Please do NOT send Unsubscribe messages to the list address.
