Diacylglycerol O-acyltransferase type-1 synthesizes retinyl esters in the retina and retinal pigment epithelium. [PDF]
PLoS ONE, 2015 Retinyl esters represent an insoluble storage form of vitamin A and are substrates for the retinoid isomerase (Rpe65) in cells of the retinal pigment epithelium (RPE).

Effect of Dietary Vitamin A, Breed, and Kidney Function on the Onset of Urinary Vitamin A Excretion and the Vitamin A Transport Complex in Growing Dogs. [PDF]
J Anim Physiol Anim Nutr (Berl)ABSTRACT Vitamin A (retinol and retinyl esters) is present in substantial amounts in the urine of healthy adult dogs, but the mechanisms affecting its excretion are poorly understood. To assess whether the onset of urinary vitamin A excretion is dependent on dietary vitamin A intake, breed, and/or parameters of kidney function, 48 puppies from two ...

Retinyl esters are hydrolyzed in early endosomes of J774 macrophages
Journal of Lipid Research, 1999 The aim of the current study was to identify the subcellular compartment(s) responsible for the hydrolysis of chylomicron remnant-retinyl esters, in J774.1 cells.

Retinol and retinyl esters: biochemistry and physiology [PDF]
Journal of Lipid Research, 2013 By definition, a vitamin is a substance that must be obtained regularly from the diet. Vitamin A must be acquired from the diet, but unlike most vitamins, it can also be stored within the body in relatively high levels.

The mPlrp2 and mClps genes are involved in the hydrolysis of retinyl esters in the mouse liver[S] [PDF]
Journal of Lipid Research, 2011 Retinyl esters are the major chemical forms of vitamin A stored in the liver, and can be delivered to peripheral tissues for conversion into biologically active forms.

Effect of Pea Protein and Arabinoxylans Mixtures as Emulsifiers on Vitamin E Absorption in Mice. [PDF]
Mol Nutr Food ResThe exclusive use of in vitro models forpredicting the bioavailability of lipophilic nutrients when complex plant‐based delivery systems are involved may not always translate to physiologicalefficacy, supporting the need of validation with in vivo models.

Dietary Vitamin A Impacts Refractory Telogen
Frontiers in Cell and Developmental Biology, 2021 Hair follicles cycle through periods of growth (anagen), regression (catagen), rest (telogen), and release (exogen). Telogen is further divided into refractory and competent telogen based on expression of bone morphogenetic protein 4 (BMP4) and wingless ...

Retinol metabolism in the mollusk Osilinus lineatus indicates an ancient origin for retinyl ester storage capacity. [PDF]
PLoS ONE, 2012 Although retinoids have been reported to be present and active in vertebrates and invertebrates, the presence of mechanisms for retinoid storage in the form of retinyl esters, a key feature to maintain whole-organism retinoid homeostasis, have been ...
