HI folks

well, cant find right word in conversation with my friend ... on first place its connected with biology ,than chemistry and math.

Math in this case make problem (we make problem cause cant agree about calculation) so we cant continue with talking about chemistry (at least meds)

Please if you have time read this and try to give right answer if you know ...THX

Nettle have needles, each needle contains some % of Acetylcholine, of course there is several of another chems but we looking and are focused at Acetylcholine.

Lets say, 10 grams of all collected leaves (for testing) contains 50% of needles but because mechanical isolation it must be presented and some leaves/plant material.

If we mechanically isolate needles (to observe and concentrate acetylcholine) we got 5 grams of "needle resin" who (beside other chems) contains our acetylcholine.

1.)Concentration of acetylcholine in leaves is 10% (we use big numbers cause cant calculate decimals )

We got (by weight) 5 grams of needles of total 10 used grams of plant material I said its ratio 50% : 50% or 1:1

(He said its .)

If you have leaves that contain50% ,by weight,resin, meaning the acetylcholine:resin ratio is 1:2

What is correct ?

2.)I told him to ratio is 1:2, means its not 50% its 33,33% : 66.66%

what I understood :

1:2 ratio means to one whole is separated on 3 equal parts.

So ratio like 1:2 is 33% : 66%

1:1 is 50% : 50%

1:2 is 33% : 66%

1:3 is 25% : 75%

etc etc

1/2 means 50%

1/3 means 33%

1/4 means 25%

1/5 means 20%

(He said its.)

Lets assume that this Urtica dioica leaves has aratio of 1:2 (which is sometime a very realistic value), meaning that half the resin is pure acetylcholine. In this case since we know that any amount of weight of acetylcholine is found in 2x that weight resin , the 10g Urtica dioica leaves will have 4g resin.acetylcholine:resin

What is correct,ratio 1:2 is33,33: 66,66or its50%?

1/2 and 1:2 isnt same or sometime 1:2 can be expressed like 50% ?

3.)I cant figure out how material what we use contains 10% of acetylcholine but needle resin contains 39% of acetylcholine.

Do not forget to ratio of leaves : resin is 50% : 50%.

OK, % of acetylcholine must be bigger by needles isolation but how almost 300% bigger but resin is just 50% of weight.

What is number ?

Acetylcholine is in needles.

If acetylcholine is 10% in 10 grams of leaves how much concentraion of acetylcholine can be improved if leaves : needles is 50%:50% ?

My brain hurts me of our conversation ,we are bad in math and thats BIG problem.Please help us or we gonna start WWIII
