Product Description
α-Linolenic acid is extracted from perilla and is an essential fatty acid that cannot be synthesized by the human body. α-Linolenic acid can affect the thrombosis process by regulating PI3K/Akt signaling. α-Linolenic acid has antiarrhythmic properties and has been linked to cardiovascular disease and cancer, among others.
Biological Activity I Assay Protocols (From Reference)
Targets
PI3K; Akt
ln Vitro
α-Linolenic acid converses into the longer chain fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)[1].
ln Vivo
In mice, α-Linolenic acid (50, 100, or 250 mg/kg; for 10 days) completely inhibits collagen- and adrenaline-induced thrombosis at 250 mg/kg[1]. Rats weighing 250–300 g have less A-V thrombus formation when given 35, 70, or 175 mg/kg of α-Linolenic acid[1]. In rats, α-Linolenic acid (70 or 175 mg/kg) inhibits collagen stimulated platelet aggregation[1].
Animal Protocol
Mice weighing at 18 ~ 22 g[1]
50, 100, 250 mg/kg
For 10 days
Toxicity/Toxicokinetics
Toxicity Summary
Alpha Linolenic Acid or ALA is considered an essential fatty acid because it is required for human health, but cannot be synthesized by humans. It is in fact a plant-derived fatty acid. Humans can synthesize other omega-3 fatty acids from ALA, including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). EPA is a precursor of the series-3 prostaglandins, the series-5 leukotrienes and the series-3 thromboxanes. These eicosanoids have anti-inflammatory and anti-atherogenic properties. ALA metabolites may also inhibit the production of the pro-inflammatory eicosanoids, prostaglandin E2 (PGE2) and leukotriene B4 (LTB4), as well as the pro-inflammatory cytokines, tumor necrosis factor-alpha (TNF-alpha) and interleukin-1 beta (IL-1 beta). Omega-3 fatty acids like ALA and its byproducts can modulate the expression of a number of genes, including those involved with fatty acid metabolism and inflammation. They regulate gene expression through their effects on the activity of transcription factors including NF-kappa B and members of the peroxisome proliferator-activated receptor (PPAR) family. Incorporation of ALA and its metabolites in cell membranes can affect membrane fluidity and may play a role in anti-inflammatory activity, inhibition of platelet aggregation and possibly in anti-proliferative actions of ALA. ALA is first metabolized by delta6 desaturease into steridonic acid.

Mechanism of Action
Alpha Linolenic Acid or ALA is considered an essential fatty acid because it is required for human health, but cannot be synthesized by humans. It is in fact a plant-derived fatty acid. Humans can synthesize other omega-3 fatty acids from ALA, including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). EPA is a precursor of the series-3 prostaglandins, the series-5 leukotrienes and the series-3 thromboxanes. These eicosanoids have anti-inflammatory and anti-atherogenic properties. ALA metabolites may also inhibit the production of the pro-inflammatory eicosanoids, prostaglandin E2 (PGE2) and leukotriene B4 (LTB4), as well as the pro-inflammatory cytokines, tumor necrosis factor-alpha (TNF-alpha) and interleukin-1 beta (IL-1 beta).

ALA is first metabolized by delta6 desaturease into steridonic acid.
Pharmacodynamics
Alpha Linolenic Acid (ALA) is an 18-carbon polyunsaturated fatty acid with three double bonds. It is also called an omega-3 fatty acid, and is essential for all mammals. Alpha-linolenic acid (or omega 3 fatty acid) intake can decrease the risk of cardiovascular diseases by 1) preventing arrhythmias that can lead to sudden cardiac death, 2) decreasing the risk of thrombosis (blood clot formation) that can lead to heart attack or stroke, 3) decreasing serum triglyceride levels, 4) slowing the growth of atherosclerotic plaque, 5) improving vascular endothelial function, 6) lowering blood pressure slightly, and 7) decreasing inflammation. ALA deficiencies can lead to visual problems and sensory neuropathy. Scaly and hemorrhagic skin or scalp inflammations may also develop.

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
