Mammals are unable to synthesize omega−3 fatty acids, but can obtain the shorter-chain omega−3 fatty acid ALA (18 carbons and 3 double bonds) through diet and use it to form the more important long-chain omega−3 fatty acids, EPA (20 carbons and 5 double bonds) and then from EPA, the most crucial, DHA (22 carbons and 6 double bonds). [2]
An omega−3 fatty acid is a fatty acid with multiple double bonds, where the first double bond is between the third and fourth carbon atoms from the end of the carbon atom chain. "Short-chain" omega−3 fatty acids have a chain of 18 carbon atoms or less, while "long-chain" omega−3 fatty acids have a chain of 20 or more.
Omega-3 fatty acids act in the opposite direction to omega-6 fatty acids, by reducing inflammation and depressing aggregation and immunosuppression. [88] The diet provided will determine the ratio of omega-6 to omega-3 fatty acids consumed; the optimal ratio of omega-6 to omega-3 fatty acids is considered to be within the range of 5:1 to 10:1.

3. Feed Your Cat Multiple Times per Day. Cats that have to hunt for their food eat about nine times a day. Cats are built differently than dogs and big cats like lions, and they do not have the ...
If you’re unsure whether your cat needs a medical evaluation, try calling the ASPCA Animal Poison Control Center (888-426-4435) or the Pet Poison Hotline (855-764-7661).
In physiological literature, it is listed by its lipid number, 18:3 (n−3). It is a carboxylic acid with an 18-carbon chain and three cis double bonds. The first double bond is located at the third carbon from the methyl end of the fatty acid chain, known as the n end. Thus, α-linolenic acid is a polyunsaturated n−3 (omega-3
In physiological literature, it is given the name 20:5(n−3). It also has the trivial name timnodonic acid. In chemical structure, EPA is a carboxylic acid with a 20-carbon chain and five cis double bonds; the first double bond is located at the third carbon from the omega end.
This list is a categorization of the most common food components based on their macronutrients. Macronutrients can refer to the chemical substances that humans consume in the largest quantities (See Nutrient);
