Mange mennesker er let forvirrede overanthocyaniner and procyanidins (OPC). In fact, they are not the same substance, and there are many differences between the two. This article explains the differences between the two in detail.
Forskelle mellem Anthocyanin og Phycocyanin
1. Kemisk struktur
Procyanidins are polyphenols, and anthocyanins are flavonoids. OPC can be produced by heating in acidic medium. Therefore, such polyphenols are named procyanidins.
2. Områder Hvor
Proanthocyanidiner findes i vid udstrækning i skind, skaller og frø af planter, såsom vindruekerner, æbleskind, jordnøddeskind og tranebær. Anthocyaniner findes i vid udstrækning i blåbær, kirsebær, jordbær, vindruer, solbær, blåbær osv. Blandt dem tre slags lilla-rødt kornblomstpigment, orange-rødt geraniumpigment og blåt{{2 }}lilla delphiniumpigment er almindelige i naturen.
3. Farveforskel
Anthocyanin er et vand-opløseligt pigment, der er et af de vigtigste pigmenter, der udgør farven på kronblade og frugter. Det kan ændre farve med den sure-base i cellevæsken. Hvis cellevæsken er sur, bliver den rødlig, og hvis cellevæsken er basisk, bliver den mere blå. Proanthocyanidiner er farveløse og dannes ved at kombinere forskellige mængder catechin eller epicatechin.
Forholdet mellem Anthocyanin og Phycocyanin
1. Both anthocyanins and OPC are based on three aromatic ring structures. Both are powerful antioxidants. Anthocyanin is a pure natural anti-aging nutritional supplement. Research has proved that it is the most effective antioxidant found by humans today. Its antioxidant properties are fifty times higher than vitamin E and two hundred times higher than vitamin C. It is 100 percent bioavailable to humans and can be detected in the blood twenty minutes after taking it.
2. Procyanidins can be converted into anthocyanins. Proanthocyanidins need to be broken down into anthocyanins in the human body before they can be absorbed by the human body. Studies have shown that the absorption of proanthocyanidins in the body is only 5 percent , while anthocyaniner can reach about 20 percent .
