• lb = 453.6 g (771.1 kCal)
• chop without refuse (Yield from 1 raw chop, with refuse, weighing 259g) = 199 гр (338.3 кКал)

• Vitamin B1 is part of the most important enzymes of carbohydrate and energy metabolism, which provide the body with energy and plastic substances, as well as the metabolism of branched-chain amino acids. Lack of this vitamin leads to serious disorders of the nervous, digestive and cardiovascular systems.
• Mixed is a part of lecithin, plays a role in the synthesis and metabolism of phospholipids in the liver, is a source of free methyl groups, acts as a lipotropic factor.
• Vitamin B5 participates in protein, fat, carbohydrate metabolism, cholesterol metabolism, the synthesis of a number of hormones, hemoglobin, promotes the absorption of amino acids and sugars in the intestine, supports the function of the adrenal cortex. Lack of pantothenic acid can lead to damage to the skin and mucous membranes.
• Vitamin B6 participates in the maintenance of the immune response, inhibition and excitation processes in the central nervous system, in the conversion of amino acids, in the metabolism of tryptophan, lipids and nucleic acids, contributes to the normal formation of erythrocytes, maintenance of the normal level of homocysteine ​​in the blood. Insufficient intake of vitamin B6 is accompanied by a decrease in appetite, a violation of the condition of the skin, the development of homocysteinemia, anemia.
• Vitamin B12 plays an important role in the metabolism and conversion of amino acids. Folate and vitamin B12 are interrelated vitamins and are involved in blood formation. Lack of vitamin B12 leads to the development of partial or secondary folate deficiency, as well as anemia, leukopenia, thrombocytopenia.
• Vitamin PP participates in redox reactions of energy metabolism. Insufficient vitamin intake is accompanied by disruption of the normal state of the skin, gastrointestinal tract and nervous system.
• potassium is the main intracellular ion that takes part in the regulation of water, acid and electrolyte balance, participates in the processes of nerve impulses, pressure regulation.
• Phosphorus takes part in many physiological processes, including energy metabolism, regulates acid-base balance, is a part of phospholipids, nucleotides and nucleic acids, is necessary for the mineralization of bones and teeth. Deficiency leads to anorexia, anemia, rickets.
• Selenium – an essential element of the antioxidant defense system of the human body, has an immunomodulatory effect, participates in the regulation of the action of thyroid hormones. Deficiency leads to Kashin-Beck disease (osteoarthritis with multiple deformities of the joints, spine and extremities), Keshan disease (endemic myocardiopathy), hereditary thrombastenia.
• Zinc is a part of more than 300 enzymes, participates in the processes of synthesis and decomposition of carbohydrates, proteins, fats, nucleic acids and in the regulation of the expression of a number of genes. Insufficient consumption leads to anemia, secondary immunodeficiency, liver cirrhosis, sexual dysfunction, and fetal malformations. Recent studies have revealed the ability of high doses of zinc to disrupt copper absorption and thereby contribute to the development of anemia.
