Bacteria with other phospholipid head groups

Bacteria with other phospholipid head groups 

A genus of bacteria, termed the Sphingobacterium, produces sphingolipids by a pathway similar to that in mammals. Clostridia produce plasmalogens (l-alk-l -enyl lipids) by an anaerobic pathway clearly different from the Oj-dependent pathway in mammals (Chapter 9). Branched-chain fatty acids are also found in which the methyl group is inserted post-synthetically into the middle of the chain, in a manner analogous to cyclopropane fatty acid synthesis (Section 5.5). S-adenosylmethionine is also the methyl donor for these reactions. The biochemistry surrounding the formation of these and many other bacterial phospholipids remains to be elucidated.
