Fatty Acid Synthesis

Copyright © 2011 Kevin Ahern

 

For fatty acid synthesis,

I must reverse the path

Of breaking fatty acids,

Though youÕll wonder Ôbout the math

 

Each cycle of addition starts

With carbons one two three

Yet the products of reactions

Number carbons evenly

 

The answer is that CO2

Plays peek-a-boo like games

By linking to an Ac-CoA

Then popping off again

 

Three reactions are like oxidations

Ôcept theyÕre backwards here

Reduction, dehydration

Then two hydrogens appear

 

The product of the process

Is a sixteen carbon chain

The links are saturated

No double bonds remain

 

For them desaturases toil

Arranging only cis

The animals get delta nine

But no more go past this

 

And last thereÕs making longer ones

Eicosanoidic fun

TheyÕre made by elongases

In the e. reticulum
