Agric. Capsaicin is the chemical in chili peppers that gives it heat. This two-step method produces raspberry ketone in 99% yield. Raspberry ketone has a structure similar to capsaicin and synephrine. [4] It can be extracted from the fruit, yielding about 1–4 mg per kg of raspberries. [5] Synthetic raspberry ketone is cheaper, with estimates ranging from a couple of dollars per pound[9] to one fifth of the cost of the natural product. [3] It is biosynthesized from coumaroyl-CoA. Raspberry ketone is a natural phenolic compound that is the primary aroma compound of red raspberries. This potential weight-loss link prompted the current research which is now being used as “support” for the over-the-top marketing claims for RK. Capsaicin, which has a similar chemical structure to raspberry ketone and anti-obese activity, showed no increase or decrease of induced luc activities at its highest treated concentration of 1 × 10 −3 M (data not shown). Zingerone (4-(4-hydroxy-3-methoxyphenyl)-2-butanone) (Fig. [5], Since the natural abundance of raspberry ketone is very low, it is prepared industrially by a variety of methods from chemical intermediates. It was discovered that Raspberry Ketone Forte increased both the expression and secretion of adiponectin. However, it’s a compound known as ‘raspberry ketone’ (which has the chemical name 4-(4-hydroxyphenyl)butan-2-one)) that is considered the ‘impact molecule’ for the aroma. [6] One of the ways this can be done is through a crossed aldol condensation followed by catalytic hydrogenation. Raspberry ketone is said to have a similar structure as capsaicin (a chemical found to increase fat metabolism in many preliminary studies). First, the raspberry ketones are chemically similar to capsaicin from cayenne and also synephrine found in bitter orange. It gives the raspberry the pleasant sweet smell.

This potential weight-loss link prompted the current research which is now being used as “support” for the over-the-top marketing claims for RK. Capsaicin, which has a similar chemical structure to raspberry ketone and anti-obese activity, showed no increase or decrease of induced luc activities at its highest treated concentration of 1 × 10 −3 M (data not shown). Zingerone (4-(4-hydroxy-3-methoxyphenyl)-2-butanone) (Fig. [5], Since the natural abundance of raspberry ketone is very low, it is prepared industrially by a variety of methods from chemical intermediates. It was discovered that Raspberry Ketone Forte increased both the expression and secretion of adiponectin. However, it’s a compound known as ‘raspberry ketone’ (which has the chemical name 4-(4-hydroxyphenyl)butan-2-one)) that is considered the ‘impact molecule’ for the aroma. [6] One of the ways this can be done is through a crossed aldol condensation followed by catalytic hydrogenation. Raspberry ketone is said to have a similar structure as capsaicin (a chemical found to increase fat metabolism in many preliminary studies). First, the raspberry ketones are chemically similar to capsaicin from cayenne and also synephrine found in bitter orange. It gives the raspberry the pleasant sweet smell.
