Muscle hemoglobin

Proteins that enable the cell to perform special functions within the organism, e.g., hemoglobin, muscle proteins, storage proteins, cilial proteins and exoproteins, such as collagen blood plasma proteins, antibodies, milk proteins, and proteohormones, structural and regulatory proteins required for the specialized function of the cell, etc.

Iron is indispensable in the human body (see Mineral nutrients). The average adult body contains 3 grams of iron. About 65% is found in hemoglobin, which carries oxygen from the lungs to the various parts of the body. Iron is also needed for the proper functioning of cells, muscles, and other tissues (4). 

The sacroplasmic proteins myoglobin and hemoglobin are responsible for much of the color in meat. Species vary tremendously in the amount of sacroplasmic proteins within skeletal muscle with catde, sheep, pigs, and poultry Hsted in declining order of sarcoplasmic protein content. Fat is also an important component of meat products. The amount of fat in a portion of meat varies depending on the species, anatomy, and state of nutrition of the animal. The properties of processed meat products are greatiy dependent on the properties of the fat included. Certain species, such as sheep, have a relatively higher proportion of saturated fat, whereas other species, such as poultry, have a relatively lower proportion of saturated fat. It is well known that the characteristic davors of meat from different species are in part determined by their fat composition. 

A healthy adult human body contains about 3 g of iron, mostly as hemoglobin. Because about 1 mg is lost daily (in sweat, feces, and hair), and women lose about 20 mg in each menstrual cycle, iron must be ingested daily to maintain the balance. Iron deficiency, or anemia, results in reduced transport of oxygen to the brain and muscles, and an early symptom is chronic tiredness. 

FIGURE 8.8 H2S production in vascular tissues. IPS production by aorta homogenate (upper panel), cultured rat vascular smooth muscle cells (VSMCs middle panel), and intact rat aorta occurs after the addition of substrate L-cysteine (L-cys) and cofactor pyridoxal L-phosphate (PLP) for the enzyme CGL located in vascular tissue. H2S production is inhibited after the CGL. 3 cyano-L-alanine (BCA) is added. Ferric Lucina pectinata hemoglobin I (metHb) is added to confirm H2S production. The quantity of metHb-sulfide produced, determined spectrophotometrically, matched the levels of H2S detected by the PHSS (after [41]). 

Treated rats had 1000 mg/kg FW liver (vs. 4.7 in controls) lowered hemoglobin, hematocrit, and red cell counts mean survival time of 67 days hepatic and renal histopathology Dose-time-dependent increase in copper concentrations in liver, spleen, and lung little accumulation in muscle and skin. Reduced growth at 2.5 and 3.75 mg/kg BW daily reduced survival at 3.75 mg/kg BW. Maximum copper concentrations recorded, in mg/kg FW (vs. saline controls,) were 710 in liver (<5), 212 in kidney (<10), 7 in lung (<1.5), 27 in spleen (<2.0) 6 in bone (<2.0) and 2.2 in testes (<1.6) Increased serum ceruloplasmin and white blood cell number... 

Exposed to 19, 32 or 51 mg/L for up to 96 h Dose- and time-dependent increase in blood glucose and lactic acid concentrations liver glycogen decreased at all nickel levels and muscle glycogen decreased at the two higher levels high nickel concentrations were associated with elevated erythrocyte number, hemoglobin, and hematocrit. Nickel accumulated in blood, liver, muscle, and especially in kidney 41...
