Biological Activity

Description Retinyl (Vitamin A) Palmitate is a more stable, synthetic version of the essential nutrient vitamin A joined to palmitic acid.
In vitro

The microencapsulation of vitamin A palmitate by gelatin-acacia complex is a promising method for converting an oily vitamin to solid powders for an aid to handling and ease of incorporation in preparations. [1]

In vivo Vitamin A Palmitate (80 mg/kg daily p.o.) or (800 mg/kg once a week p.o.) dose-dependently decreases the size of papillomas in mice, the daily administration induces a somewhat higher extent of regression than the weekly application if the total doses are compared. Water miscible solutions of Vitamin A Palmitate as well as of Vitamin A acid given by the oral route elicit the same effect on papillomas. [2] Vitamin A Palmitate (A single simultaneous injection of 150 g) enhances cell-mediated immunity to sheep red blood cells(SRBC) as early as 3 days following immunization, and the enhancement persists for at least 3 weeks. [3]


Solubility (25°C)

In vitro Ethanol 5 mg/mL (9.52 mM)
DMSO 3 mg/mL (5.71 mM)
Water Insoluble

* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

Bio Calculators

Molarity Calculator

Molarity Calculator

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:

Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)

  • Mass
    Molecular Weight

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration (start) x Volume (start) = Concentration (final) x Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

  • C1

* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
