Precursor of AA is DGLA (dihomogammalinolenic acid) which is a successor of (omega-6) LA. The enzyme d5d (delta-5-desaturase) catalyses the genesis of AA. This step is competetively limited by omega-3 fatty acids beeing catalysed to EPA.

Eicosanoids are not precursors of AA, but are made of AA.

How do vegetarians do without arachidonic acid?

arachidonic acid is made in the body by the enzymes d5d,d6d and elongase from Linolic acid (LA). AA is not essential, LA is essential. Dietary arachidonic acid is present in red meat and poses a risk by promoting inflammatory reactions.

What is arachidonic acid?

In chemical structure, arachidonic acid is a carboxylic acid with a 20-carbon chain and four cis double bonds. In Biology, arachidonic acid is a polyunsaturated fatty acid that is present in the phospholipids (especially phosphatidylethanolamine, phosphatidylcholine and phosphatidylinositides) of membranes of the body's cells, and is abundant in the brain.

Which fatty acid is converted to arachidonic acid which serves as the precursor to the localized hormones known as eicosanoids?

Arachidonic acid is a 20:4(delta5,8,11,14) derivative fatty acid from linoleic acid. Linoleic and linolenic acids are "essential fatty acids" for mammals and they must be consumed from plant sources. Once consumed, linoleic acid may be converted to other polyunsaturated acids, particularly gamma-linoleic acid, eicosatrienoate and arachidonic acid (or eicosatetranoate) which can be only from linoleic acid.

What is arachidonic acid used for?

An arachidonic acid is used as an anabolic body building supplement in a variety of products. It is used in order to help its users build muscle more easily.

Is arachidonic acids necessary for the synthesis of eicosapentaenoic and docosahexaenoic acids?

Yes, arachidonic acids are necessary for the synthesis of eicosapentaenoic and docosahexaenoic acids. Arachidonic acid is a type of acid that is found in peanut oil.

What is the chemical formula of arachidic acid?

C20H32O2 Arachidonic acid.

How much Arachidonic Acid is contained in peanuts?

Peanut oil doesn't contain arachidonic acid (20:4) but does contain about 1.5% arachidic acid (20:0).

What is the function of arachidonic acid?

Arachidonic acid generated for signaling purposes appears to be derived by the action of a phosphatidylcholine-specific cytosolic phospholipase A2 (cPLA2, 85 kDa), whereas inflammatory arachidonic acid is generated by the action of a low-molecular-weight secretory PLA2 (sPLA2, 14-18 kDa) arachidonic acid is also used in the biosynthesis of anandamide. Arachidonic acid is necessary for the repair and growth of skeletal muscle tissue. Arachidonic acid helps to maintain hippocampal cell membrane fluidity. It also helps protect the brain from oxidative stress by activating perioxisomal proliferator-activated receptor-y
