• 説明

  Myristic acid, also called tetradecanoic acid , is a common saturated fatty acid with the molecular formula CH₃(CH₂)₁₂COOH. A myristate is a salt or ester of myristic acid.
  Myristic acid is named after the nutmeg Myristica fragrans. Nutmeg butter is 75 % trimyristin, the triglyceride of myristic acid. Besides nutmeg, myristic acid is also found in palm kernel oil, coconut oil, butter fat and is a minor component of many other animal fats. It is also found in spermaceti, the crystallized fraction of oil from the sperm whale.
  Myristic acid is also commonly added co-translationally to the penultimate, nitrogen-terminus, glycine in receptor-associated kinases to confer the membrane localisation of the enzyme. The myristic acid has a sufficiently high hydrophobicity to become incorporated into the fatty acyl core of the phospholipid bilayer of the plasma membrane of the eukaryotic cell. In this way, myristic acid acts as a lipid anchor in biomembranes.
  The ester isopropyl myristate is used in cosmetic and topical medicinal preparations where good absorption through the skin is desired.
  Reduction of myristic acid yields myristyl aldehyde and myristyl alcohol.

• 化学的特性

  Myristic acid occurs as an oily white crystalline solid with a faint odor.

• 天然物の起源

  Reported found in nutmeg, palm seed, sperm whale oil, blue cheese, burley tobacco, cooked beef and chicken, fish, rum, apricot, banana, lemon and grapefruit juice, cranberry, guava, grapes, melon, papaya, raspberry, strawberry fruit and jam, cucumber, tomato, many cheeses, thyme, breads, butter, milk, lamb liver, pork, hop oil, beer, cognac, whiskies, peanut oil, cocoa, tea, coconut meat and milk, cloudberry, beans, passion fruit, mushroom, mango, starfruit, tamarind, kelp, cardamom, rice, buckwheat, watercress, malt, wort, loquat, Bourbon vanilla, lemon balm, shrimp, nectarine, crab, scallop, squid, cape gooseberry, Chinese quince, pawpaw and sweet grass oi

• 使用

  Myristic Acid is a common saturated fatty acid found in nutmeg, palm kernel oil, coconut oil and butter fat.

• 製造方法

  From fatty acid mixture of palm seed oil

• 調製方法

  Myristic acid occurs naturally in nutmeg butter and in most animal and vegetables fats. Synthetically, it may be prepared by electrolysis of methyl hydrogen adipate and decanoic acid or by Maurer oxidation of myristyl alcohol.

• 定義

  ChEBI: A straight-chain, fourteen-carbon, long-chain saturated fatty acid mostly found in milk fat.

• 一般的な説明

  Oily white crystalline solid.

• 空気と水の反応

  Insoluble in water.

• 火災危険

  Myristic acid is probably combustible.

• 応用例（製薬）

  Myristic acid is used in oral and topical pharmaceutical formulations. Myristic acid has been evaluated as a penetration enhancer in melatonin transdermal patches in rats and bupropion formulations on human cadaver skin.Further studies have assessed the suitability of myristic acid in oxymorphone formulations and clobetasol 17-propionate topical applications.Furthermore, polyvinyl alcohol substituted with myristic acid (as well as other fatty acids) at different substitution degrees has been used for the preparation of biodegradable microspheres containing progesterone or indomethacin.

• 安全性プロファイル

  Poison by intravenous route. Mutation data reported. An eye and human skin irritant. When heated to decomposition it emits acrid smoke and irritating fumes.

• 安全性

  Myristic acid is used in oral and topical pharmaceutical formulations and is generally regarded as nontoxic and nonirritant at the levels employed as an excipient. However, myristic acid is reported to be an eye and skin irritant at high levels and is poisonous by intravenous administration. Mutation data have also been reported.
  LD₅₀ (mouse, IV): 0.043 g/kg
  LD₅₀ (rat, oral): >10 g/kg

• 貯蔵

  The bulk material should be stored in a well-closed container in a cool, dry, place.

• 純化方法

  Purify the acid via the methyl ester (b 153-154o/10mm, n25 1.4350), as for capric acid. [Trachtman & Miller J Am Chem Soc 84 4828 1962.] Also purify it by zone melting. It crystallises from pet ether, and is dried in a vacuum desiccator containing shredded wax. [Beilstein 2 IV 1126.]

• 不和合性

  Myristic acid is incompatible with strong oxidizing agents and bases.

• 規制状況(Regulatory Status)

  GRAS listed. Included in the FDA Inactive Ingredients Database (oral capsules). Included in nonparenteral medicines licensed in the UK.
