. Molecular weights of fatty acids vary over a wide range. The carbon skeleton of any fatty acid is unbranched. Some fatty acids are saturated, i.e., each carbon atom is connected to its carbon atom neighbors by single bonds; and some fatty acids are unsaturated, i.e., contain at least one carbon-carbon double bond (see chemical bondchemical bond,
mechanism whereby atoms combine to form molecules. There is a chemical bond between two atoms or groups of atoms when the forces acting between them are strong enough to lead to the formation of an aggregate with sufficient stability to be regarded as an

Several epidemiologic and clinical studies, and randomized controlled trials (RCTs) have suggested that n-3 polyunsaturated fatty acids or omega-3 fatty acids might be a useful treatment for MDD through their effects on cell communication, neurotransmitters, and inflammation.
However, several epidemiological studies have reported that the low quality of dietary intake of omega-3 fatty acids is associated with psychiatric illness, and fish and seafood are sources of essential fatty acids and other nutrients.
