Explanation:

Plants synthesise a huge variety of fatty acids although only a few are major and common constituents [1]. Broadly speaking, long-chain fatty acids are synthesised de novo from small precursors ultimately derived from photosynthate. Two enzyme systems are utilised, acetyl-CoA carboxylase and fatty acid synthase (Fig. 1). The end products of this synthesis are usually the saturated fatty acids palmitate and stearate with the latter predominating (in most plants by 2-3 times that of palmitate). Once the long-chain acids have been produced they can be subject to elongation, desaturation and further modifications (Fig. 1). Unlike acetyl-CoA carboxylase and fatty acid synthase, which are soluble enzymes, the elongases are membrane-bound and sited in the endoplasmic reticulum. Only recently have the details of such reactions started to be elucidated at the molecular level. Elongases are coded by FAE genes while the desaturases are coded by FAD genes.
