Aliphatic Acids and Glycolipides 



The metabolic origins of some of the acids in this section can 

 be deduced from the foregoing chapter. Among these are 

 pyruvic, glyceric, acetic, formic, propionic and lactic acids. 



Many of the other simpler acids are recognizable as members 

 of the citric acid cycle and ancillary routes. The citric acid 

 cycle (tricarboxylic acid cycle or Krebs cycle) is outlined 

 below :
