In the present study, when the enzyme activity decreased (between 14 and 21 days of aging), evidenced by the reduction of myofibrillar
degradation in this period (MFI), the pH also decreased (Table 1).
Desorbed protein from 2-hour-oxidized samples exhibited greater losses of fluorescence and more extensive polymerization of myosin than myofibrillar
protein in the continuous phase, as detected by sodium dodecyl sulfate polyacrylamide gel electrophoresis.
Myosin is the main component of the myofibrillar
fraction, which makes up the majority of muscular proteins.
muscle protein synthesis rates subsequent to a meal in response to increasing doses of whey protein at rest and after resistance exercise.
Central accumulations of myofibrillar
material that produce areas devoid of mitochondria (and thus devoid of staining for oxidative enzymes like NADH, SDH, and COX) at, or near, the center of myofibers.

Gelation properties of chicken myofibrillar
protein induced by transglutaminase cross-linking.
2011), NaCl concentrations commonly added to meat products provide the ionic strength necessary for dissolution and extraction of the myofibrillar
proteins responsible for emulsification, gelatinization and water retention capacity, among others.
It is also known as flat-pup syndrome, twisted legs, turtle pup, splay leg (paraparesis), splay weak (tetraparesis) and myofibrillar
hypoplasia (Verhoeven, 2006).
Protein degradation may be responsible for the disorganization of the myofibrillar
structure (Delbarre-Ladrat et al.
Although this could be a result of fast degradation of myofibrils when the damaged area is small and subjected to large plasma flow, our data indicate that washout of cTnT and therefore also cTnI can occur without extensive myofibrillar
degradation, because cTnT extraction can be almost complete after 90 min.
Effect of heart failure on skeletal muscle myofibrillar
protein content, isoform expression and calcium sensitivity.
