Uptake and metabolism of β-apo-8′-carotenal, β-apo-10′-carotenal, and β-apo-13-carotenone in Caco-2 cells

β-Apocarotenoids are eccentric cleavage products of carotenoids formed by chemical and enzymatic oxidations. They occur in foods containing carotenoids and thus might be directly absorbed from the diet. However, there is limited information about their in

Preparation method of beta-apo-8 '-carotene aldehyde

The invention discloses a preparation method of beta-apo-8 '-carotene aldehyde, which comprises the following steps: by using beta-apo-8-carotene ethyl ester as a raw material, conducting reducing tofor an alcohol under the action of a reducing agent, and conducting oxidizing to form beta-apo-8'-carotene aldehyde, wherein the reducing agent is one or more of sodium borohydride, lithium borohydride and lithium aluminum hydride, and an oxidizing agent is one or more of pyridinium chlorochromate, hydrogen peroxide, manganese dioxide and 4-hydroxy-2,2,6,6-tetramethyl-piperidinooxy. The target product beta-apo-8 '-carotene aldehyde can be generated only through two-step reaction, the reaction raw materials are cheap and easy to obtain, the process route is simple, the reaction conditions are mild, the process operation is easy to implement, and the method has great industrial value.

Synthesis of carotenoid-monosaccharide conjugates via azide–alkyne click-reaction

Carotenoid pentynoates were coupled to protected and unprotected sugar azides via an azide-alkyne click-reaction using bis-triphenylphosphano-copper(I)-butyrate (C3H7COOCu(PPh3)2) complex. Protected sugars delivered the conjugates with excellent yields, whereas with unprotected ones amphipathic carotenoid-sugar derivatives were obtained in good or moderate yields in a simple way.

Towards carotenoid dendrimers: Carotenoid diesters and triesters with aromatic cores

For the evaluation of the synthesis of dendritic esters from carotenoids, various carotenols or their succinates were reacted with bi- and trifunctional aromatic acids and alcohols. Several methods were tested, from which the Steglich esterification was f

Electronic Relaxation in Long Polyenes
