Vitamin A Aldehyde

Enzymatic oxidation of vitamin A aldehyde to vitamin A acid.

Studies indicating that vitamin A (1) and vitamin A aldehyde (2) are metabolized to water-soluble degradation products and CO% provide support for the suggestion (3) that there exists an oxidative pathway of major importance in the metabolism of vitamin A. The detection of vitamin A aldehyde in the liver (4, 5) and observations (6-8) that dietary vitamin A acid supports the growth of vitamin A-...

Vitamin A-aldehyde adducts: AMD risk and targeted therapeutics.

Although currently available treatment options for age-related macular degeneration (AMD) are limited, particularly for atrophic AMD, the identification of predisposing genetic variations has informed clinical studies addressing therapeutic options such as complement inhibitors and anti-inflammatory agents. To lower risk of early AMD, recommended lifestyle interventions such as the avoidance of...

Studies in vitamin A. 6. Conversion in vivo of vitamin A aldehyde (retinene(1)) to vitamin A(1).

The colorimetric reaction between vitamin A2 aldehyde and antimony trichloride.

1. Columns of Sephadex G-25 have been used for the preliminary fractionation of tryptic digests of casein. 2. Fractions from Sephadex columns have been examined for their ability to stimulate the growth of a strain of Streptococcus equi8imili8. Maximum stimulatory activity appeared to be localized in a fairly narrow region of the total peptide material. 3. Further fractionation of peptides deri...
