'''Margaric Acid''' is a [[saturated fatty acid]] that is naturally found in animal and vegetable fats. Its chemical formula is C17H34O2. Margaric acid is a white, waxy solid at room temperature and is virtually insoluble in water. It is named after the Greek word 'margarites', meaning pearl, due to its pearly luster.

== History ==
[[File:Heptadecanoic_acid.png|thumb|right|Structural formula of heptadecanoic acid]]
Margaric acid was first isolated in 1813 by French chemist [[Michel Eugène Chevreul]]. He initially believed it to be a distinct [[fatty acid]], but it was later discovered to be a mixture of [[stearic acid]] and [[palmitic acid]]. The term 'margaric acid' is now used to refer to the saturated fatty acid with 17 carbon atoms, also known as heptadecanoic acid.


== Properties ==
'''Margaric acid''', also known as '''heptadecanoic acid''', is a [[saturated fatty acid]] with the chemical formula C<sub>17</sub>H<sub>34</sub>O<sub>2</sub>. It is a [[straight-chain]] [[fatty acid]] and is classified as a [[long-chain fatty acid]]. Margaric acid is not commonly found in nature but can be synthesized in the laboratory.
Margaric acid is a [[saturated fatty acid]] with a chain of 17 carbon atoms. It is a white, waxy solid at room temperature and is virtually insoluble in water. It has a melting point of 63°C and a boiling point of 351°C. Margaric acid is non-toxic and is generally recognized as safe for consumption by the [[Food and Drug Administration]] (FDA).


== Uses ==
==Structure and Properties==
Margaric acid is used in the production of [[cosmetics]], [[soaps]], and [[lubricants]]. It is also used in the food industry as a flavoring agent and preservative. In addition, margaric acid is used in the production of [[biofuels]] and in the synthesis of other chemicals.
Margaric acid consists of a 17-carbon chain with a carboxylic acid group at one end. The molecular structure can be represented as CH<sub>3</sub>(CH<sub>2</sub>)<sub>15</sub>COOH. As a saturated fatty acid, it contains no [[double bonds]] between the carbon atoms in the chain, which contributes to its solid state at room temperature.


== Health Effects ==
==Occurrence==
As a [[saturated fatty acid]], margaric acid can contribute to increased levels of [[low-density lipoprotein]] (LDL) cholesterol, which can increase the risk of [[heart disease]]. However, the impact of margaric acid on heart health is less clear than that of other saturated fatty acids, and more research is needed in this area.
Margaric acid is rarely found in natural sources. It is sometimes detected in trace amounts in [[dairy products]] and certain [[animal fats]]. It is more commonly encountered as a component of [[synthetic mixtures]] of fatty acids.


== See Also ==
==Synthesis==
Margaric acid can be synthesized through the [[hydrogenation]] of [[oleic acid]] or by the [[oxidation]] of [[heptadecanol]]. These processes involve chemical reactions that add hydrogen atoms to unsaturated bonds or introduce oxygen to alcohol groups, respectively.
 
==Uses==
While not widely used in industry, margaric acid can serve as a reference compound in [[analytical chemistry]] and is sometimes used in the production of [[soaps]] and [[cosmetics]]. Its properties as a saturated fatty acid make it useful in studying the behavior of similar compounds.
 
==Health Implications==
The health effects of margaric acid are not well-studied due to its rarity in the diet. However, as a saturated fatty acid, it is generally advised to consume such fats in moderation as part of a balanced diet.

A saturated fatty acid



Structural formula of heptadecanoic acid

Margaric acid, also known as heptadecanoic acid, is a saturated fatty acid with the chemical formula C17H34O2. It is a straight-chain fatty acid and is classified as a long-chain fatty acid. Margaric acid is not commonly found in nature but can be synthesized in the laboratory.

Structure and Properties[edit]

Margaric acid consists of a 17-carbon chain with a carboxylic acid group at one end. The molecular structure can be represented as CH3(CH2)15COOH. As a saturated fatty acid, it contains no double bonds between the carbon atoms in the chain, which contributes to its solid state at room temperature.

Occurrence[edit]

Margaric acid is rarely found in natural sources. It is sometimes detected in trace amounts in dairy products and certain animal fats. It is more commonly encountered as a component of synthetic mixtures of fatty acids.

Synthesis[edit]

Margaric acid can be synthesized through the hydrogenation of oleic acid or by the oxidation of heptadecanol. These processes involve chemical reactions that add hydrogen atoms to unsaturated bonds or introduce oxygen to alcohol groups, respectively.

Uses[edit]

While not widely used in industry, margaric acid can serve as a reference compound in analytical chemistry and is sometimes used in the production of soaps and cosmetics. Its properties as a saturated fatty acid make it useful in studying the behavior of similar compounds.

Health Implications[edit]

The health effects of margaric acid are not well-studied due to its rarity in the diet. However, as a saturated fatty acid, it is generally advised to consume such fats in moderation as part of a balanced diet.
