L-carnitines most important role in cells is to transport fatty acids (as acylcarnitines) across the mitochondrial membranes for breakdown in the mitochondrial pathway of fat metabolism called fatty acid oxidation or beta-oxidation

An anion exchange chromatography process for purifying a GLP-1 peptide from a mixture comprising said peptide and related impurities, comprising the step of:separating said GLP-1 peptide and said related impurities of said mixture by elution in a solution consisting essentially of an organic modifier, water, optionally a salt component, and optionally a buffer, with a linear or step gradient or isocratically in salt component and/or with a linear or step pH-gradient or at a constant pH-value, wherein the pH-gradient or pH-value should be in the range where said peptide has a negative local or overall net charge different from the local or overall negative net charge of said related impurities so as to remove said related impurities, and wherein the ratio of organic modifier to water, on a weight percent basis, is from 1:99 to 99:1, such as 1:99 to 80:20, 20:80 to 80:20, 30:70 to 70:30, 35:50 to 50:35, or 40:50 to 50:40

Because that figure comes from rodent research, many start patients at the low end (about 5 mcg/kg or a flat 250 mcg) and adjust over one to two weeks
