Abstract: The purpose of this study was to describe the relationship between dietary supplementation and concentration of γ‐ and δ‐tocopherol (TOH) in tissues of Atlantic salmon, Salmo salar, L., when α‐TOH was fed at a constant level. Post‐smolt Atlantic salmon (230 g) in duplicate tanks were fed a fish‐meal‐based diet with 250 g kg−1 lipid. Different combinations of RRR‐tocopherylacetate preparations were added to give the following levels of TOH (mg kg−1) in diets 1–4, respectively: 150α; 150α+ 100δ; 150α+ 50γ+ 50δ; … Show more

“…For instance, Ackman and Cormier (15) found that metabolically active dark muscle in cod was richer in αT than the white muscle tissue, since confirmed for Atlantic salmon (34). In this new experiment, the liver and testes exhibited similar proportions of tissue phospholipids, but the γT/αT ratios differed by about 75% (Fig.…”

“…3) than would have been expected from the relatively high phospholipid content, possibly due to γT deposition in neutral lipid of adipocytes attached to connective tissue (35,36), as well as the redirection of essential αT from muscle phospholipids into phospholipids of other and more critical tissues. Hamre and Lie (34) suggest that each organ may have unique combinations of mechanisms by which they take up lipids and tocopherols from plasma.…”

“…The a-TTP facilitates selective uptake of RRR-a-tocopherol from hepatic circulation and may enhance systemic trafficking and tissue deposition of RRR-a-tocopherol (Blatt et al 2001). Although a-TTP has not been isolated from a teleost model, apparent patterns of discriminatory tocopherol trafficking in sunshine bass and Atlantic salmon Salmo salar (Hamre and Lie 1997) are similar to those observed in mammalian models. It is reasonable to assume the increased biological activity (Trushenski and Kohler 2006) and the high level of tissue retention we observed for NSVE is related to the affinity of a-TTP for RRR-a-tocopherol.…”

“…Dietary c-tocopherol is readily deposited in salmon muscle (Sigurgisladottir, Parrish, Ackman, & Lall, 1994). The two isomers forms (a-and c-tocopherol) can be active in salmon, depending the concentrations of these compounds in the diet (Hamre & Lie, 1997;Sigurgisladottir et al, 1994). The chemical antioxidant activity of tocopherols in oils is dependent on their concentrations and generally decreases from c to a (Jung & Min, 1990).…”
