[en] 1. 1. Actomyosin extracts of trunk, heart, and head muscles from barbel (Barbus barbus L.) were analyzed by SDS-polyacrylamide gel electrophoresis to study their myosin heavy chain composition. 2. 2. Four heavy chain isoforms were found: trunk white, trunk red, and ventricle muscles yielded one heavy chain typical of the muscle type; head muscles devoid of red fibers displayed two heavy chain isoforms, the slow migrating one corresponding to the trunk white muscle type. 3. 3. The electrophoretic mobility of red and ventricle myosin heavy chains related to that of white isoforms appeared highly modified by the glycerol content of the gels.
