12-Methyltridecanal

Description

12-Methyltridecanal, also known as 12-MT aldehyde or isotetradecan-1-al, 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, 12-methyltridecanal is considered to be a fatty aldehyde lipid molecule. 12-Methyltridecanal is considered to be a practically insoluble (in water) and relatively neutral molecule. 12-Methyltridecanal has been primarily detected in urine. Within the cell, 12-methyltridecanal is primarily located in the membrane (predicted from logP) and cytoplasm. 12-Methyltridecanal has a broth, cooked, and cooked meat taste.

Chemical properties

12-Methyltridecanal has an aroma characteristic of stewed beef (meaty, tallow)

Occurrence

Stated to be of natural origin; has not been reported in any food items by TNO (Nutrition and Food Research) (TNO, 2000)

The Uses of 12-Methyltridecanal

12-Methyltridecanal (MT) smelling tallowy, beef-like was formed from plasmalogens when beef was boiled. It was found in microorganisms samples isolated from beef.

Biosynthesis

It is believed that 12-methyltridecanal is preferentially a constituent of ruminants, possibly being synthesized by the bacteria in the rumen, andincorporated in the plasmalogens.
