How nutrients influence it

Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.

How nutrients reach it in more than one step

Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What acts on it

  1. The principal analogues detected in oleoresin capsicum were capsaicin and dihydrocapsaicin, and these appeared to be the analogues primarily responsible for the pungency of the sample, with pungency proportional to total capsaicinoid concentration at roughly 15,000 Scoville Heat Units per microgram of total capsaicinoids.

  2. The capsiate to dihydrocapsiate ratio presented a higher variation between genotypes and developmental stages than the capsaicin to dihydrocapsaicin ratio, and capsaicinoids could already be determined at 10 days post-anthesis in Bhut Jolokia with an accumulation pattern different from that of the capsinoids.

Where it participates (unsigned role)

  1. Analysis of commercially available pepper spray products demonstrated variability in capsaicinoid concentrations among products from different manufacturers and among different product lots from the same manufacturer, indicating that commercial pepper products are not standardised for capsaicinoid content even though they are classified by Scoville Heat Units, which could alter potency and jeopardise the safety and health of users and assailants.

  2. Much of the published literature on capsaicin is based on pepper extracts, which are typically a mixture of capsaicin and other capsaicinoids including norhydrocapsaicin, dihydrocapsaicin, homocapsaicin and homodihydrocapsaicin, which is why this study examined the in vitro metabolism of pure capsaicin; that metabolism was similar in human, rat and dog microsomes, yielding 16-hydroxycapsaicin, 17-hydroxycapsaicin and 16,17-dehydrocapsaicin, with biotransformation slow in human skin so that cytochrome P450 metabolism in skin is minimal relative to hepatic metabolism.
