The melanocyte-stimulating hormones are also called
intermedins, they are isolated from the intermediate lobe
of the pituitary in those animals which have a distinct
intermediate lobe.

Melanocyte-stimulating activity refers to the ability of
these hormones to cause dispersion of pigment granules in
melanocytes, producing a darkening of the skin.

Two types of MSHs have been isolated. ?-MSH is the most
potent melanocyte-stimulating hormone; ?-MSH has about 50%
of the activity of ?-MSH, while ACTH and the LPHs have
about 1%.

I have given the protocol for the cyclodextrin glygosyl transferase assay: One ml of appropriately diluted enzyme sample was incubated at 60 °C for 15 min with 5 ml of 1% (w/v) gelatinized soluble starch in 50 mM, 7.0-pH Tris–HCl buffer. Reaction was terminated by boiling the reaction mixture for 3 min and reaction volume was made to 10 ml with distilled water. Two ml of above reaction mixture was withdrawn and mixed with 3 ml of Tris–HCl buffer, 5 ml of 125 mM Na2CO3, and 0.5 ml of phenolphthalein (25 mg phenolphthalein/100 ml absolute alcohol). Absorbance was measured at 550 nm. The percent decrease of sample was calculated with respect to control containing 5 ml of buffer, 5 ml of sodium carbonate and 0.5 ml of phenolphthalein. where Acontrol = absorbance of control and Atest = absorbance of sample. The amount of β-cyclodextrin (β-CD) produced was estimated from the standard graph of 0–500 μg/ml β-CD concentration against % decrease in absorbance. One unit of CGTase was defined as the amount of enzyme required to produce 1 μm of β-CD/min. Please can you suggest me the formula for the defination given in the last line
