Glutamine
In human blood, glutamine is the most abundant free amino acid.
Omega-3 fatty acid
Three omega−3 fatty acids are important in human physiology, α-linolenic acid (18:3, "n"-3; ALA), eicosapentaenoic acid (20:5, "n"-3; EPA), and docosahexaenoic acid (22:6, "n"-3; DHA). These three polyunsaturates have either 3, 5, or 6 double bonds in a carbon chain of 18, 20, or 22 carbon atoms, respectively. As with most naturally-produced fatty acids, all double bonds are in the "cis"-configuration, in other words, the two hydrogen atoms are on the same side of the double bond; and the double bonds are interrupted by methylene bridges (--), so that there are two single bonds between each pair of adjacent double bonds.
