6-Hydroxychroman (6-chromanol) is the fundamental unit of the tocopherols (vitamin E), tocols, and tocotrienols, as well as of ubi-, toco-, and phyllochromanol.
See also: chroman, chromene, chromenol.
Synonym(s): hydroxychroman

In general, the correlation between determined AOP of investigated antioxidants (Table 4) which are structurally different compounds such as hydroxycinnamic acids, trihydroxybenzoic acid, flavanols and their derivatives, vitamers of vitamin C, and synthetic chromanol, is much poorer than correlation between the types of assays.
Vitamin E has chromanol ring in its structure which donates hydrogen to free radicals thus making them unreactive (Kumari et al., 2013).
It contains extracts of avocado and soybean, hyaluronic acid, vitamin E, sodium carboxymethyl beta glucan, dimethylmethoxy chromanol, and trimethylglycine.
At the same time, [I.sub.Ks] channel blocker, chromanol 293B, increased the field potential duration in control EBs, but not in patient-specific EBs.
Nifedipine (10 [micro]M) and chromanol B (10 [micro]M) were added to the bath solution to block L-type calcium and [I.sub.Ks] currents, respectively.
The polyphenolic flavonoids share a basic 15-carbon skeleton core structure (represented as C6-C3-C6) consisting of two phenylbenzene (chromanol) rings linked through a pyran ring.
Tocopherols and tocotrienols have a chromanol head and a side chain at C-2 position.
Chromanol ring of tocopherols donates its phenolic hydrogen to reduce the free radical and is itself oxidised to the quinone form.
It is comprised of a family of hydrocarbon compounds characterised by a chromanol ring with a phytol side chain referred to as tocopherols and tocotrienols.
These compounds exert antioxidant activity by one electron reduction of the phenolic group in the chromanol moiety.
Different numbers and positions of methyl groups present on the chromanol head of individual molecules ("R" positions, Figure 1) distinguish each isomer by a Greek letter [alpha], [beta], [gamma]or [delta].
