Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the class of molecules, which has anti-inflammatory properties, that is produced by human body while metabolising omega-3 fatty acids?
A
Alpha-linolenic acid
B
Endocannabinoid epoxides
C
Hydroxylapatite
D
Eicosapentaenoic acid
Explanation: 

Detailed explanation-1: -Eicosanoids produced from arachidonic acid have roles in inflammation. EPA also gives rise to eicosanoids and these often have differing properties from those of arachidonic acid-derived eicosanoids. EPA and DHA give rise to newly discovered resolvins which are anti-inflammatory and inflammation resolving.

Detailed explanation-2: -Animal experiments and clinical intervention studies indicate that omega-3 fatty acids have anti-inflammatory properties and, therefore, might be useful in the management of inflammatory and autoimmune diseases.

Detailed explanation-3: -They discovered that omega-3 fatty acids inhibit an enzyme called cyclooxygenase (COX), which produces the prostaglandin hormones that spark inflammation. The action is similar to what happens when one takes an aspirin, which disrupts the COX-2 signaling pathway, thus reducing inflammation and pain.

Detailed explanation-4: -Fish oils are rich in omega-3 essential fatty acids, which have strong anti-inflammatory properties: They significantly reduce the release of several elements that play a part in inflammation from your white blood cells.

Detailed explanation-5: -Omega-3 polyunsaturated fatty acids (n-3 PUFAs) are known to be anti-inflammatory and to alter gene expression within the cells. Emerging evidence indicates that one of the mechanisms for this process involves the alteration of epigenetic markers, such as DNA methylation.
