The biosynthesis of fatty acids and lipids meets two imperatives in the
cell :
- supply of fatty acids necessary for the synthesis of structural lipids;
- storage of energy.
The synthesis of fatty acids goes through a dehydration step during its synthesis. and its catabolism goes through a hydration stage, which shows the importance of H2O molecules to build lipids (even cholesterol).
Synthesis of the fatty acid:
firstly, acetyl-ACP and malonyl-ACP were condensed, followed by reduction of acetoacetyl-ACP to β-hydroxybutyryl-ACP, followed by dehydration of β-hydroxyacyl-ACP, and finally reduction of the double bond by NADPH + H
Catabolism:
The reverse steps will occur: a beta oxidation, a hydration of the molecule, and finally another oxidation.
The physical appearance of a trait is called the phenotype of an organism.

If only one parent has sickle cell allele, then the child won’t get sickle cell disease. However, if both parents have sickle cell allele, then the probability of their child having the disease is pretty high
