Pig muscle

The puzzle had its inception with the independent observation in the early 1930s by Kurzok and Lieb [1] and later von Euler [2] that seminal fluid contained a substance that caused the contraction of isolated guinea pig muscle strips. The latter named this putative compound prostaglandin in the belief that it originated in the prostate gland the ubiquity of those substances was only uncovered several...

Biological tissues The electrode was constructed from a slice of pig muscle (0.9-1 mm thick), stuck over the flat end of a glass pH electrode and covered with a nylon net fixed with a rubber ring. The calibration graph of potential versus concentration was rectilinear from 20 to 600 pg/mL of acetylcholine in 1 mM. KC1 at 30°C. There was no interference from a wide range of biological compounds. Recovery was 98.2% and the coefficient of variation was less than 8% (n = 8). [111]... 

In another study, Lin et al.46 reported that there was a depressive effect of tryptophan deficiency on protein synthesis rate in pig muscle. Also, earlier studies revealed that, among the essential amino acids, tryptophan was one of the most critical at weaning on the effect of its deficiency on the appetite of piglets47 in the same way that its deficiency affected the appetite of older pigs.48... 

Lin et al.137 reported that there was a depressive effect of tryptophan deficiency on the protein synthesis rate in pig muscle. Also, Cortamira et al.138 reported that the fractional protein synthesis rates in piglet muscle (longis-simus dorsi and semitendinosus) were increased in animals fed tryptophan-adequate diets compared to controls (tryptophan-inadequate diets). This was confirmed in a later study by Ponter et al.135...

For glyceraldehyde-3-phosphate dehydrogenase, conflicting conclusions have been reached by different workers (47 49). From one analysis of initial rate data, for the pig muscle enzyme, it appears that with glycer-aldehyde as substrate the mechanism is random (SO), whereas with glyceraldehyde 3-phosphate there is random combination of this substrate and NAD followed by phosphate as the compulsory third substrate (48). On the other hand, inhibition studies with the rabbit muscle enzyme indicate an ordered mechanism in which NAD is the first and acyl acceptor the last substrate to combine (51). More detailed comparative initial rate studies with the several aldehydes w hich act as substrates (Section II,E), preferably by a fluorimetric method (11,47), and isotope exchange studies at equilibrium are needed for this enzyme.
