What is the difference between Pal-GHK and IGF-1 LR3?
Pal-GHK is a palmitoylated form of the GHK tripeptide used in cosmetic-science and fibroblast-culture research (lipopeptide, MW about 578.8 g/mol).
Which is heavier, Pal-GHK or IGF-1 LR3?
Pal-GHK has a molecular weight of about 578.8 g/mol and IGF-1 LR3 about 9111 g/mol (PubChem), so IGF-1 LR3 is heavier by 8,532.2 g/mol, a ratio of 15.74. This means 1 mg of Pal-GHK contains 1,727.7 nmol versus 109.8 nmol for IGF-1 LR3.
How many mg of IGF-1 LR3 are equimolar to 1 mg of Pal-GHK?
1 mg of Pal-GHK (MW 578.8) is 1,727.7 nmol. The same number of moles of IGF-1 LR3 (MW 9111) weighs 15.741 mg. Equimolar comparisons matter when testing two compounds side by side in the same assay.
A 0.1 mg vial of IGF-1 LR3 equals how many mg of Pal-GHK in moles?
0.1 mg of IGF-1 LR3 (MW 9111) is 0.01098 µmol. The same amount of Pal-GHK (MW 578.8) would weigh 0.006353 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 1 mg vial of IGF-1 LR3 equals how many mg of Pal-GHK in moles?
1 mg of IGF-1 LR3 (MW 9111) is 0.1098 µmol. The same amount of Pal-GHK (MW 578.8) would weigh 0.06353 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
A 10 mg vial of Pal-GHK equals how many mg of IGF-1 LR3 in moles?
10 mg of Pal-GHK (MW 578.8) is 17.277 µmol. The same amount of IGF-1 LR3 (MW 9111) would weigh 157.4 mg. This equimolar conversion lets two compounds be compared at matched molar amounts in the same experiment.
