Epsilon

... stupid is the English, since it calls basic and basic with the same word, isn't it? :lol:) are little complicated. Just remember, that lysine has epsilon-NH2, it is often used for binding, modifications etc. Thus it must have alpha-carbon (the one between NH2 and COOH), beta, gamma, delta and ...

... 25320 M^-1cm^-1. Is this the correct units for this value? The path length is 1cm and the absorbance is 0.57 and the MW is 2438Da. I have epsilon = 25320 / (g/L)*cm, is this correct? so if c= A/epsilon, is the calculation just 0.57/25320 = .0000225 moles/Liter, or .0000225M? i cant figure ...

The other question is: why I have to multiply for the number of base pairs if I obtain the concentration of the oligo with UV-vis using an epsilon. The epsilon has already in count the number of bases since it is estimated with the nearest-neibour principle. Am I wrong? Sorry I start to loose ...

... The simply state the receptor is an arrangement of 5 protein subunits, 2 alpha, one beta, one gamma, one delta. Then they later say delta becomes epsilon. No reference, no definition. I'll look into hemoglobin.

... that human nAChRs in membrane of nerve cells have an (Alpha)2(Beta,Gamma,Delta) quaternary structure in the embryonic form and (Alpha)2(Beta,Epsilon,Delta) in the adult. Firstly, does embryonic/adult refer to the host organism, i.e. the human? Secondly, my impression was the alpha subunits ...
