9-cis-β-Carotene, a precursor of retinal, is cleaved by beta-carotene oxygenase 1 (BCMO1) to produce 9-cis-retinal. It inhibits photoreceptor degeneration and restores retinal function in vivo.

β-Carotene (Standard) 是 β-Carotene 的标准品，适用于定量分析、质量控制及生化实验等相关研究。β-Carotene (Provitamin A) 是一种天然存在的视黄醇（维生素 A）前体。它是一种 ROS 调节剂，具有抗氧化和抗炎活性。它可作为抗氧化剂或者促氧化剂，可诱导乳腺癌细胞凋亡，具有抗癌活性。

Retinyl acetate (Vitamin A acetate) 是一种视黄醇的合成乙酸酯形式衍生物，有抗肿瘤和化学预防活性的潜能。

Ketoisophorone (2,6,6-Trimethyl-2-cyclohexene-1,4-dione) 是工业上重要的环状内酯，是合成类胡萝卜素和调味剂的关键中间体。

Lycopene (ψ,ψ-Carotene) 是一种番茄及其产品和其他红色水果和蔬菜中天然存在的类胡萝卜素，具有抗氧化活性。

Dihydro-β-erythroidine hydrobromide(DHβE) is a potent, oral active and competitive antagonist of neuronal nicotinic acetylcholine receptors (nAChRs). Dihydro-β-carotene hydrobromide showed selectivity to α4β4 and α4β2nAChR, with IC50 of 0.19 and 0.37 μM,

β-Carotene-13C10 (Provitamin A-13C10) 是一种13C 标记的β-Carotene，属于类胡萝卜素，是维生素 A 的天然前体。作为一种 ROS 调节剂，β-Carotene 具备抗氧化和抗炎特性，其抗氧化或促氧化功能取决于自身特性及其所处生物环境的氧化还原电位。此外，β-Carotene 能诱导乳腺癌细胞凋亡 (apoptosis)，展现出抗癌特性。

9(Z),11(E)-Conjugated linoleic acid is an isomer of linoleic acid that has been found in beef and milk fat.1It binds to peroxisome proliferator-activated receptor α (PPARα; IC50= 140 nM) and activates the receptor in a reporter assay using COS-1 cells expressing mouse PPARα when used at a concentration of 100 μM.29(Z),11(E)-Conjugated linoleic acid inhibits TNF-α-inducedGLUT4expression and increases insulin-stimulated glucose transport in 3T3-L1 adipocytes.3Dietary administration of 9(Z)11(E)-conjugated linoleic acid reduces serum fasting glucose, insulin, and triglyceride levels and decreases white adipose tissue macrophage infiltration inob/obmice. It also increases body weight gain and body fat in weanling mice.4[Matreya, LLC.
