Chemical changes in muscle

Abstract

SOME of the chemical changes responsible for activity in vertebrate skeletal muscle are fairly well known. On the other hand, in plain muscle, cardiac muscle and certain muscles of invertebrate animals, these changes are not clearly understood, possibly because the analytical methods Which have been used for vertebrate skeletal muscle do not always give good results on applica- tion to other types of muscle. For this reason it was thought advisable to examine and if possible to improve the methods available for the estimation of carbohydrates and lactic acid in muscle.
