• chop, excluding refuse (yield from 1 raw chop, with refuse, weighing 85 g) = 42 g (124.3 kcal)

• Vitamin B2 participates in oxidation-reduction reactions and promotes the colors’ receptivity by the visual analyzer and dark adaptation. Insufficient intake of vitamin B2 is accompanied by violation of the skin’s condition, mucous membranes, violation of light, and twilight vision.
• Vitamin B12 plays an important role in the metabolism and conversion of amino acids. Folate and vitamin B12 are interrelated in vitamins involved in hematopoiesis. A lack of vitamin B12 leads to the development of partial or secondary folate deficiency and anemia, leukopenia, and thrombocytopenia.
• Vitamin PP participates in redox reactions of energy metabolism. Insufficient intake of vitamins is accompanied by disturbance of the skin’s normal condition, gastrointestinal tract, and nervous system.
• Phosphorus takes part in many physiological processes, including energy metabolism, regulates the acid-alkaline balance, part of phospholipids, nucleotides, and nucleic acids, necessary for mineralization of bones and teeth. Deficiency leads to anorexia, anemia, rickets.
• Iron is included with different functions of proteins, including enzymes. Involved in the transport of electrons, oxygen provides a course of redox reactions and activation of peroxidation. Insufficient consumption leads to hypochromic anemia, myoglobinuria atony of the skeletal muscles, fatigue, cardiomyopathy, atrophic gastritis.
• Copper is part of enzymes with redox activity involved in iron metabolism and stimulates the absorption of proteins and carbohydrates—the processes involved in providing tissues with oxygen. Deficiency is manifested by malformations of the cardiovascular system and skeleton, development of connective tissue dysplasia.
• Zinc is part of over 300 enzymes involved in the synthesis and breakdown of carbohydrates, proteins, fats, nucleic acids, and the regulation of expression of several genes. Insufficient intake leads to anemia, secondary immunodeficiency, liver cirrhosis, sexual dysfunction, presence of fetal malformations. Research in recent years revealed that high doses of zinc could disrupt copper absorption and thus contribute to anemia’s development.
