Mass spectral trace of sa-um by ESI+-MS method. m/z: 300-351-monoacyl glycerol, with higher intensity around m/z: 300–304 region due to arachidonic acid, typical fatty acid of non-ruminant species; m/z: 550–650-diacyl glycerol species; m/z: 750–850-triacyl glycerol species; with a modest levels of triacyl phospholipid species in the m/z: 900 region, due to smaller quantity of muscle adipose tissues in sa-um
