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.

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 role does cyclooxygenase play in pain and inflammation?
Cyclooxygenase (COX) is an enzyme involved in the production of prostaglandins, which are lipid mediators that contribute to pain and inflammation. COX helps convert arachidonic acid into prostaglandins, which then promote vasodilation, fever, and sensitization of pain receptors, leading to the symptoms of pain and inflammation. Inhibiting COX activity with drugs like NSAIDs can help reduce pain and inflammation.
What is the full name for DNA and RNA?
DNA- Deoxyribo Nucleic Acid RNA-Ribo Nucleic Acid
What is an example of a eicosanoid?
Eicosanoids come in two broad groups: the leukotrienes and the prostanoids, both of which are involved in signaling between cells. They are encountered frequently in the study of inflammation, and are commonly considered inflammatory mediators (ways for the cells of the immune system to signal where, when, and how inflammation should take place). An example of a prostanoid is prostaglandin E2 (PGE2), which plays a role in the sensitization of pain receptors during inflammation.
What type of acid is DNA?
DNA stands for deoxyribonucleic acid. It is a type of nucleic acid that contains genetic instructions for the development, functioning, growth, and reproduction of all living organisms.
Is CO2 an acid?
CO2 itself is not an acid, since it doesnt make hydrogen ions (H+). But it does become an acid when in contact with water. CO2 in water becomes carbonic acid. Carbonic acid (H2CO3) is a weak acid capable of splitting of a H+.
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.
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.
How many double bonds are present in arachidonic acid?
there are 4 double bonds in arachnoid acid..thanks..
What is DHA and ARA?
docosahexaenoic acid and arachidonic acid
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.
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
What is an arachidonate?
An arachidonate is a salt or ester of arachidonic acid.
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.
Prostaglandins are derived from what?
derived from arachidonic acid released from phospholipids in the cell membrane
