Octanal
Octanal, also known as 1-caprylaldehyde or aldehyde C-8, belongs to the class of organic compounds known as medium-chain aldehydes. These are an aldehyde with a chain length containing between 6 and 12 carbon atoms. Thus, octanal is considered to be a fatty aldehyde lipid molecule. A saturated fatty aldehyde formally arising from reduction of the carboxy group of caprylic acid (octanoic acid). Octanal is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. Octanal exists in all eukaryotes, ranging from yeast to humans. Octanal is an aldehydic, citrus, and fat tasting compound. Octanal is commonly found in high concentrations in limes, caraway, and mandarin orange (clementine, tangerine) and in lower concentrations in wild carrots and carrots. Octanal has also been detected, but not quantified in several different foods, such as cherry tomato, brussel sprouts, alaska wild rhubarbs, sweet marjorams, and sunflowers.
