Properties of retinoids
TLDR
In this review, procedures for handling and storage of retinoids and biological samples containing them have been described, and simplified procedures for derivatizations and purification, and methods for quantitation ofretinoids have been presented.

beta-carotene is converted primarily to retinoids in rats in vivo.
TLDR
The view that central cleavage is by far the major pathway for the formation of vitamin A from beta-carotene in healthy rats in vivo is agreed.

Induction of differentiation of human promyelocytic leukemia cell line HL-60 by retinoyl glucuronide, a biologically active metabolite of vitamin A.
TLDR
It is concluded that retinoyl beta-D-glucuronide can arrest HL-60 cell proliferation and induce their differentiation into mature granulocytes; it may act by itself or by being hydrolyzed to retinoic acid, which could be immediately utilized and metabolized.

Bioactivities of N‐(4‐hydroxyphenyl) retinamide and retinoyl β‐glucuronide
TLDR
Two derivatives of retinoids show interesting physiologic effects and potentially beneficial pharmacologic actions that are effective in the topical treatment of acne in humans and in animals.

Chemical synthesis and growth-promoting activity of all-trans-retinyl beta-D-glucuronide.
TLDR
Water-soluble retinyl beta-D-glucuronide, when administered intraperitoneally in saline (0.9% NaCl), supports well the growth of vitamin A-deficient rats and is susceptible to hydrolysis by bacterial beta- glucuronidase.
