What's the difference between creatin and creatine?
Creatin
Definition:
(n.) A white, crystalline, nitrogenous substance found abundantly in muscle tissue.
Example Sentences:
(1) It was found that the skeletal muscle enzyme of the chick embryo is independent of the presence of creatine and consequently is another constitutive enzyme like the creatine kinase of the early embryonic chick heart.
(2) In cardiac tissue the adenylate system is not a good indicator of the energy state of the mitochondrion, even when the concentrations of AMP and free cytosolic ADP are calculated from the adenylate kinase and creatine kinase equilibria.
(3) In the absence of an authentic target for the MASH proteins, we examined their DNA binding and transcriptional regulatory activity by using a binding site (the E box) from the muscle creatine kinase (MCK) gene, a target of MyoD.
(4) Defibrotide prevents the dramatic fall of creatine phosphokinase activity in the ischemic ventricle: metabolic changes which reflect changes in the cells affected by prolonged ischemia.
(5) We have studied the postnatal ontogeny of creatine kinase (CK) and the glycolytic enzymes phosphoglycerate kinase (PGK), phosphoglycerate mutase (PGM), enolase (En), and pyruvate kinase (PK) in rat brain and uterus.
(6) As a means of assessing the value of fetal serum-creatine-kinase (S.C.K.)
(7) Linear regression analysis of creatine kinase activity in sera and DPH fluorescence anisotropy in lymphocytes from DMD patients showed a negative correlation (r = -0.93, p less than 0.001).
(8) In 24-hour urine collection creatine excretion was lower, particularly in the infants daily creatinine excretion was positively correlated with body weight, body length and age.
(9) Activities of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), creatine phosphokinase (CPK), and lactate dehydrogenase (LDH) were determined in plasma, kidney, liver, and muscle from five species of captive birds.
(10) After 60 min recovery, exercise was performed for 8-10 min each at 20, 30, 40 and 50 W. Measurements of pulmonary oxygen uptake, heart rate, blood pressure, leg blood flow, and femoral arterial-venous differences of oxygen content and lactate were performed as well as determination of ATP, creatine phosphate (CP) inosine monophosphate (IMP) and lactate concentrations on biopsy material from the quadriceps muscle before and immediately after the intense exercise, and at 3, 10 and 60 min into recovery.
(11) Secondly, as a consequence of the proximity of mitochondrial creatine kinase to the translocase, there appears to be a kinetic preference for ADP generated by the forward creatine kinase reaction.
(12) The cardiotropic effect of broncholytic agents of different groups used for treatment of bronchial asthma was analyzed by using the method of determination of isoenzyme of MB creatine phosphokinase (CPK) and total CPK in the blood of the patients.
(13) In order to identify those signals that are associated with each of the central complexes of the equilibrium mixture, spectra were obtained for a complex of enzyme, Mn(II)ATP, and a nonreactive analogue of creatine, 1-(carboxymethyl)-2-iminoimidazolidin-4-one, which is a newly synthesized competitive inhibitor.
(14) Cardiac hypertrophy due to a chronic hemodynamic overload is accompanied by isoformic changes of two proteins of the thick filament of the sarcomere, myosin, and creatine phosphokinase.
(15) One of them (IP 6.85) showed a complete inhibition by anti-creatine kinase-M antibodies, whereas the other showed only 50% inhibition.
(16) Furthermore, a significant correlation between maximal creatine kinase levels and plasma ANF levels at a 75-watt workload and a significant inverse correlation between left ventricular ejection fraction and plasma ANF levels at a 75-watt workload were observed.
(17) At 10--15 mM of creatine in the perfusate the force of the myocardium contraction was increased.
(18) When myopathy developed later with elevated serum creatine phosphokinase and myoglobin levels, the electromyogram was nonmyopathic, and polymyositis was confirmed by muscle biopsy.
(19) The peak level of serum myoglobin was reached appreciably earlier than the peak values of serum creatine phosphokinase activity.
(20) Antisera against the crystallized creatine kinase isoenzymes from human skeletal muscle (MM) and from human brain (BB) were produced in rabbits.
