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.

Which hormone-like molecules are NOT produced from arachidonic acid?
Insulin, testosterone, and estrogen are examples of hormone-like molecules that are not produced from arachidonic acid. Arachidonic acid is a precursor for eicosanoids such as prostaglandins, thromboxanes, and leukotrienes.
What is arachidonic acid used for?
Arachidonic acid is a type of omega-6 fatty acid that serves as a precursor for various compounds involved in inflammation and immune responses, such as prostaglandins and leukotrienes. It plays a role in cell signaling processes and is necessary for normal bodily functions, but can also contribute to inflammation if its levels become imbalanced.
Which Acid is used to synthesize arachidonic acid?
Arachidonic acid is not synthesized from a specific acid. It is mainly obtained from dietary sources like meat, eggs, and fish. The body can also convert linoleic acid, an omega-6 fatty acid, into arachidonic acid through a series of enzymatic reactions.
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.
Is arachidonic acids necessary for the synthesis of eicosapentaenoic and docosahexaenoic acids?
Yes, arachidonic acid is necessary for the synthesis of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) through the desaturation and elongation processes in the body. These omega-3 fatty acids are derived from arachidonic acid, which is essential for the biosynthesis of EPA and DHA.
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?
Arachidonic acid is a type of polyunsaturated omega-6 fatty acid found in animal-based foods. It plays a crucial role in the production of inflammatory compounds called eicosanoids, which are involved in various physiological processes in the body, such as the immune response and blood clotting.
What is DHA and ARA?
docosahexaenoic acid and arachidonic acid
How many double bonds are present in arachidonic acid?
there are 4 double bonds in arachnoid acid..thanks..
What is the chemical formula of arachidic acid?
C20H32O2 Arachidonic acid.
What are the precursors for synthesis of the eiconsanoids?
Arachidonic acid is the precursor for the synthesis of eicosanoids, which are signaling molecules involved in inflammation and immune responses. It is released from cell membranes by phospholipase A2 in response to various stimuli. Once released, arachidonic acid can be metabolized by cyclooxygenase (COX) or lipoxygenase (LOX) enzymes to form prostaglandins, thromboxanes, and leukotrienes.
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).
