Metabolite Identification
Common NamePalmitaldehyde
DescriptionPalmitaldehyde, also known as 1-hexadecanal, belongs to the class of organic compounds known as fatty aldehydes. These are long chain aldehydes with a chain of at least 12 carbon atoms. Thus, palmitaldehyde is considered to be a fatty aldehyde lipid molecule. Palmitaldehyde is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.

Enzymes

General function:
Involved in carboxy-lyase activity
Specific function:
Cleaves phosphorylated sphingoid bases (PSBs), such as sphingosine-1-phosphate, into fatty aldehydes and phosphoethanolamine. Elevates stress-induced ceramide production and apoptosis.
Gene Name:
SGPL1
Uniprot ID:
O95470
Molecular weight:
63523.265
Reactions
Sphinganine 1-phosphate → O-Phosphoethanolamine + Palmitaldehydedetails
General function:
Involved in G-protein coupled receptor protein signaling pathway
Specific function:
Photoreceptor required for image-forming vision at low light intensity. Required for photoreceptor cell viability after birth. Light-induced isomerization of 11-cis to all-trans retinal triggers a conformational change leading to G-protein activation and release of all-trans retinal
Gene Name:
RHO
Uniprot ID:
P08100

General function:
Involved in acyl-CoA binding
Specific function:
Binds medium- and long-chain acyl-CoA esters with very high affinity and may function as an intracellular carrier of acyl-CoA esters. It is also able to displace diazepam from the benzodiazepine (BZD) recognition site located on the GABA type A receptor. It is therefore possible that this protein also acts as a neuropeptide to modulate the action of the GABA receptor
