Retinol esterification in Sertoli cells by lecithin-retinol acyltransferase

, 1989
Esterification of retinol occurs during the metabolism of vitamin A in the testis. An acyl- CoA:retinol acyltransferase (ARAT) activity has been described for microsomes isolated from testis homogenates. That activity was also observed here in microsomal

Retinol and Retinol-Binding Protein Stabilize Transthyretin via Formation of Retinol Transport Complex

, 2016
Transthyretin (TTR) is a plasma hormone carrier protein associated with hereditary and senile forms of systemic amyloid disease, wherein slow tetramer disassembly is thought to be an obligatory step. Plasma transport of retinol is carried out exclusively

Cellular retinol-binding protein (type two) is abundant in human small intestine.

Journal of Lipid Research, 1987
Human small intestine was found to contain a retinol-binding protein similar to the gut-specific cellular retinol-binding protein, type two [CRBP (II)], described in the rat.

Vitamin A equivalency of ß-carotene in healthy adults: limitation of the extrinsic dual-isotope dilution technique to measure matrix effect

, 2009
Data on the vitamin A equivalency of ß-carotene in food are inconsistent. We quantified the vitamin A equivalency (¿g) of ß-carotene in two diets using the dual-isotope dilution technique and the oral¿faecal balance technique.

19F-NMR studies of retinol transfer between cellular retinol binding proteins and phospholipid vesicles

, 1997
The cellular retinol binding proteins, CRBP and CRBP II, are implicated in the cellular uptake of retinol and intracellular trafficking of retinol between sites of metabolic processing.

Transport of retinol in the duck plasma [PDF]

, 1981
. Retinol-binding protein and prealbumin were isolated from duck plasma by chromatography on DEAE-cellulose-and DEAE-Sephadex A-50, gel filtration on Sephadex G-100 and preparative Polyacrylamide gel electrophoresis.

Blood Biomarkers of Helicobacter pylori‐Infected Chronic Gastritis in Active Versus Stable Phases: A Clinical Indicator Analysis Combined With Proteomic and Metabolomic Investigations

iMetaMed, EarlyView.
Combining clinical data with serum proteomics and metabolomics, the HGB–CAPZB–acetic acid model was developed as a potential diagnostic index to distinguish the active and stable stages of Helicobacter pylori‐infected chronic gastritis, and the related mechanism was explored through multi‐omics.

Mechanism of pH-induced Release of Retinol from Retinol-Binding Protein

, 1993
A hypothesis is proposed explaining the mechanism of pH-induced release of retinol from retinol-binding protein (RBP). A number of conservative positively charged side chains located on the retinol-binding face of the RBP molecule are involved in salt ...
