of 167 amino acids and has a molecularweightof about 16 kD or 16,000 g/mol. The DNA sequence for the protein was determined by Friedman in 1994 and was found on the obese (ob) gene [4]. The leptin receptor, the molecular structure on the cell surface that binds with leptin, is encoded by the diabetes (db) gene.
Leptin is a 16-kD protein that plays a critical role in the regulation of body we
of VOCs is 1.2 wt%
② Pseudo - Assumption
Rate determining step = Surface reaction
Almost catalyst reaction is determined by surface reaction
VOCs multi system = Toluene pure system
Average molecularweight = 90.5
Toluene’s molecularweight = 91.4
∴ Average molecularweight ≒ Toluene’s molecularweight

of differences in diffusion rates.
These are arising from differences in molecular size and solubility.
This means that the resistance increases with increasing molecularweight.
The solutes separate by passing through the membrane that
behaves like a fibre filter and separation occurs by a sieving
action based on the pore diameter and particle size
