Beschreibung
Linolenic acid (LA), also known as Alpha-linolenic acid (ALA), is an omega-3 essential fatty acid with a wide range of biological activities such as cardiovascular protection, anticancer, neuroprotection, anti-osteoporosis, anti-inflammatory, and antioxidant.LA is mainly sourced from plants, such as nuts and seeds, and is used for the endogenous synthesis of LC omega-6 fatty acids. It is used medicinally as a nutritional supplement and to treat dietary deficiencies or imbalances.
Chemische Eigenschaften
clear light yellow to yellow liquid
Occurrence
linolenic acid occurs as the glyceride in many seed fats. It is an essential fatty acid in the diet.
Verwenden
linolenic acid is also known as alpha-linolenic acid; omega-3. An essential fatty acid found in most drying oils. It is slightly irritating to the mucous membranes. It may be used in a cosmetic preparation for any of the following broad uses: anti-static, cleansing, emollient, skin-conditioning, and surfactant properties.
Definition
ChEBI: Alpha-linolenic acid is a linolenic acid with cis-double bonds at positions 9, 12 and 15. Shown to have an antithrombotic effect. It has a role as a micronutrient, a nutraceutical and a mouse metabolite. It is an omega-3 fatty acid and a linolenic acid. It is a conjugate acid of an alpha-linolenate and a (9Z,12Z,15Z)-octadeca-9,12,15-trienoate.
benefits
Linolenic acid (LA) is an essential fatty acid with anti-inflammatory, anti-bacterial, anti-atherosclerotic and anti-cancer activities, and has a variety of health benefits, including: lowering high blood pressure and cholesterol, lowering the risk of heart disease, maintaining the membrane fluidity of the epidermal transdermal water barrier, improving the barrier function of the skin, decreasing inflammation, regulating sebum secretion, moisturising the scalp, promoting hair growth and prevents hair breakage. It also has a whitening effect on over-pigmented skin.
Allgemeine Beschreibung
Linolenic acid is a clear colorless liquid. (NTP, 1992)
Air & Water Reaktionen
Oxidizes in air to form peroxides, which spontaneously ignite. Insoluble in water. Sensitive to heat and moisture.
Reaktivit?t anzeigen
Linolenic acid is incompatible with bases, oxidizing agents and reducing agents. Also incompatible with peroxides, oxygen and water.
Brandgefahr
Linolenic acid is probably combustible.
Carcinogenicity
Narisawa et al. found that
diets high in perilla oil (with high a-linolenic acid but also
high levels of linoleic acid) lowered the risk of colon cancer
in a rat model initiated with the carcinogen N-methyl-Nnitrosourea.
Okuno found a suppressive effect on diethylnitrosamine-
induced heptaocarcinogenesis in male Fischer
344 rats treated with either safflower (high in linoleic
acid) or perilla oil (high in both linoleic and α-linolenic
acids). Kitano et al. found that 10% α-linolenic
acid did not promote urninary bladder cancer initiated in rats
with N-butyl-N-(4-hydrocybutyl)nitrosamine. Mice fed
a-linolenic acid at 5–10% of the diet had increased mammary
gland ductular cell proliferation.
