Protein metabolism în diabet


Diabetes mellitus is characterized by derangements in the metabolism not govern protein metabolism of non-diabetic subjects applied equally to those.Protein requires insulin for metabolism, as do carbohydrate and fat, but has minimal effects on blood glucose levels. In well-controlled diabetes, large amounts of protein have the potential to contribute to glucose production, minimally increase blood glucose levels, and require additional small amounts of insulin.In the case of protein metabolism, as in certain studies on the pathways of glucose and fat metabolism, these observations reveal striking intracellular effects of insulin in many tissues. Within most tissues the effect of insulin appears to find expression predominantly at the microsomal level.

Generally speaking, a resistance to the effect of insulin on amino acid and protein metabolism in T2DM could either be irrelevant and difficult to demonstrate, or, alternatively, be translated into some clinically and instrumentally measurable alterations.Moreover, this net muscle protein catabolism is due to a net increase in protein breakdown rather than a decline in protein synthesis (1–4). In contrast, despite substantial alterations in glucose and lipid metabolism, the effect of type 2 diabetes on changes in protein metabolism is at best subtle, and results are inconsistent (5–8).The observed effects of insulin deficiency in diabetic patients vary in different body compartments; most of the effects of insulin on protein synthesis appear.

Because the increase in protein synthesis in splanchnic tissues is greater than the increase in protein breakdown, insulin deprivation results in a net accretion of protein in the splanchnic bed. In contrast, in skeletal muscle, there is a net increase in protein breakdown during insulin deprivation, resulting in a net release of amino acids.Protein turnover is the balance between protein synthesis and protein degradation. Proteins are naturally occurring polymers made up of repeating units of 20 different amino acids and range from small peptide hormones of 8 to 10 residues to very large multi-chain complexes of several thousand amino acids.In contrast, despite substantial alterations in glucose and lipid metabolism, the effect of type 2 diabetes on changes in protein metabolism is at best subtle, and .

Following a meal there is a surplus of food nutrients in circulation. Insulin acts upon them in several ways. In doing so, its actions extend to several substances.[5] These substances include: Amino acids; Carbohydrates Fats; Amino acids are the chemical building blocks that make up proteins.

Protein Metabolism in Type 1 Diabetes. The regulation of protein synthesis and breakdown is a central component of metabolic and physiological homeostasis. 12 Type 1 diabetic people are in a profound protein catabolic state without insulin replacement. The role of insulin in protein metabolism has been investigated in whole-body, regional and individual protein studies.Because the methodology for the study of protein metabolism has been refined and the potential effect of deranged protein metabolism has been more widely appreciated, there has been an increase in focus on protein metabolism in diabetes. Whole-body protein catabolism is the net result of increased protein breakdown, decreased protein synthesis or a combination of relative changes in both synthesis and breakdown.Arch Intern Med. 1977 Apr;137(4):507-13.

Amino acids are categorized into two types - non-essential amino acids (can be synthesized by the body) and essential amino acids which cannot, and have to be provided from the diet. The non-essential amino acids are glycine, alanine, serine, asparagine, aspartic.In normal man, the fasting state is characterized by release of alanine and glutamine from muscle and in situ muscle catabolism of branched chain amino acids .
