If what you are after are the structural co-ordinates of particular amino acids crystalized individually (i.e. considered as small molecules independently of any role in proteins), then you should find them along with other small molecules in the Cambridge Structural Database.


The intracellular receptor for cortisol is called NR3C1. To my knowledge, a direct (competitive) effect of anabolic steroids on the binding of cortisol to NR3C1 has never been proven. The anabolic effects can easily be explained by other targets. A good starting point for further reading might be this review: ...


As this question is a first post it is probably just a basic question about protein synthesis, which @Sean Johnson has answered adequately. However I’m not quite sure. And as I used to work in protein synthesis (but am a rather out of touch now) I decided to look at the recent literature a little to address some more esoteric or obscure questions it raised ...


Whether or not there are multiple start and stop codons depends on what you mean by "start codon" and "stop codon". The start codon has the sequence "AUG", and the stop codon has the sequence "UAG", "UAA", or "UGA". Both the pre-mRNA and the mature-mRNA can, and usually do, contain multiple instances of all of these sequences. However, only one "AUG" ...
