GtoPdb Ligand ID: 13100

Synonyms: all-trans-Zeaxanthin | Beta,beta-carotene-3,3'-diol | Zeaxanthol
PDB Ligand
Compound class: Natural product or derivative
Comment: Zeaxanthin is a carotenoid compound that gives certain plants and micro-organisms their characteristic yellow colours. Humans derive zeaxanthin from their diet.
In humans ingested zeaxanthin is accumulated in the macula (central retina), where it is a component of the macular pigment (a blue light filter and antioxidant) that is important for optimal visual acuity [1]. Its use is permitted in many jurisdictions as a safe ingredient for inclusion in food supplements that claim to maintain eye health and visual performance, although clinical benefit has not been robustly established.

2D Structure

An image of the ligand's 2D structure. For small molecules with SMILES these are drawn using the NCI/CADD Chemical Identifier Resolver. Click on the image to access the chemical structure search tool with the ligand pre-loaded in the structure editor. For other types of ligands, e.g. longer nucleotides and peptides, a manually drawn representation of the molecule may be provided.

Physico-chemical Properties

Calculated molecular properties are available for small molecules and natural products (not peptides). Properties were generated using the CDK toolkit. All properties were selected to enable the prediction of the Lipinski Rule-of-Five profile or ‘druglikeness’ for each ligand. For more info on each category see the help pages.

SMILES / InChI / InChIKey

SMILES (Simplified Molecular Input Line Entry Specification) A specification for unambiguously describing the structure of chemical molecules using short ASCII strings. Canonical SMILES specify a unique representation of the 2D structure without chiral or isotopic specifications. Isomeric SMILES include chiral specification and isotopes.

Standard InChI (IUPAC International Chemical Identifier) and InChIKey InChI is a non-proprietary, standard, textual identifier for chemical substances designed to facilitate linking of information and database searching. An InChIKey is a simplified version of a full InChI, designed for easier web searching.
