Alkaloids such as narcotene,papavarine,morphine are
synthesised from aminoacid tyrosine.
all morphine group of alkaloids are derived from
tyrosine.methyl group is donated by methionine in this process.
Tyrosine->Dihydoxy phenyl pyruvic
acid->dopamine->nor-laudanosoline-.reticuline->salutaridine->salutaridinol->thebaine->codeinone->codeine->morphine.
I this procedure we can synthesise all types of phenanthrene
alkaloids.

What happen to a denaturated enzyme regarding its functionality? How that result can be explained with the help of the lock and key model?
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 Two ml of above reaction mixture was withdrawn and mixed with 3 ml of Tris–HCl buffer, 5 ml of 125 mM Na2CO3, and 0.5 ml of phenolphthalein (25 mg phenolphthalein/100 ml absolute alcohol).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
