Grip Strength Heatmap: 30 significant metabolites visually depicted lower metabolite expression in those with low grip strength (Blue) as compared to those with higher grip strength (Green). The significant metabolites consisted of lipid and lipid-like molecules (LPC 22:6, LPC 20:4, LPC plasmalogen 16:1, LPE 20:4, SM 22:0, carnitine 16:0, SM 18:1, LPC 18:3, carnitine 7:0, LPC 18:0, LPC 16:0, alphaglycerophosphocholine), organic acids and derivatives (asymmetric dimethylarginine, gamma aminobutyric acid, oxalate, alpha-hydroxybutyrate/beta-hydroxybutyrate/ hydroxyisobutyrate, n-acetylcarnosine), organoheterocyclic compounds (kynurenic acid, xanthurenate, 7-methylguanine, 5-hydroxymethyl-4-methyluricil), alkaloids and derivatives (trigonelline), organic nitrogen compounds (methylguanidine), carboximidic acids (N carbomoyl beta alanine), amino acids and peptides (proline, valine, threonine and glycylglycine) and phosphocholine isomer 2.
