Five molecular forms of AChE are present in the slow (ALD) and twitch (PLD) muscles of the chick. These forms have 4 S, 7 S, 11 S, 15 S and 20 S sedimentation coefficient in sucrose gradient. The heaviest forms, the 20 S and 15 S of AChE are absent in uninnervated muscles and present in innervated muscles. In innervated muscles, the 20 S and 15 S AChE are present in both nerve-free segments and end-plates zones. The 20 S and 15 S which are not specifically associated with the end-plate zones in the chick could be considered as a biochemical "marker" of neuromuscular interactions.
鸡的慢肌（ALD）和快肌（PLD）中存在五种乙酰胆碱酯酶分子形式。这些形式在蔗糖梯度中的沉降系数分别为4S、7S、11S、15S和20S。最重的形式，即乙酰胆碱酯酶的20S和15S，在未受神经支配的肌肉中不存在，而存在于受神经支配的肌肉中。在受神经支配的肌肉中，20S和15S乙酰胆碱酯酶存在于无神经节段和终板区。鸡中与终板区无特异性关联的20S和15S可被视为神经肌肉相互作用的生化“标志物”。
