Branched

Oct 19, 2017The branched-chain amino acids (BCAAs) isoleucine, leucine, and valine are essential amino acids that are obtained from the diet through protein-containing foods. Uptake of BCAAs into the brain occurs at the blood-brain barrier through a competitive transport carrier that they share with other large neutral amino acids,

Genetic disorders of BCAA metabolism produce amino acidopathies and various forms of organic aciduria with severe clinical consequences. A metabolic block in the oxidative decarboxylation of BCAA caused by mutations in the mitochondrial branched-chain a-keto acid dehydrogenase complex (BCKDC) results in Maple Syrup Urine Disease (MSUD) or branched-chain ketoaciduria.

Branched Chain Amino Acids: Beyond Nutrition Metabolism

Branched chain amino acids (BCAAs), including leucine (Leu), isoleucine (Ile), and valine (Val), play critical roles in the regulation of energy homeostasis, nutrition metabolism, gut health, immunity and disease in humans and animals. As the most abundant of essential amino acids (EAAs), BCAAs are not only the substrates for synthesis of nitrogenous compounds, they also serve as signaling

Aug 08, 2019This is a term that refers to a special group of genetic disorders of amino acid metabolism that involve branched-chain amino acids that include leucine, isoleucine, and valine. The disorders result in the accumulation of toxic acidic chemicals that cause adverse effects. There are four main types of organic acidemia. Maple syrup urine disease

Overview of Amino Acid Metabolism Disorders

Leucine, isoleucine, and valine are the branched-chain amino acids that are the building blocks of proteins in the body. If these amino acids are not properly metabolized, they and their toxic by-products build up in the blood and urine, causing certain disorders.

Nutrition and Metabolism Disorders

Oct 31, 2017A metabolic disorder occurs when the metabolism process fails and causes the body to have either too much or too little of the essential substances needed to stay healthy. Our bodies are very sensitive to errors in metabolism. The body must have amino acids and many types of proteins to perform all of its functions.

Maple syrup urine disease

Maple syrup urine disease is an inherited disorder in which the body is unable to process certain protein building blocks (amino acids) properly. The condition gets its name from the distinctive sweet odor of affected infants' urine. It is also characterized by poor feeding, vomiting, lack of energy (lethargy), abnormal movements, and delayed development.

Branched

Human proteins are assembled from 20 amino acids, nine of which are considered "essential" because they cannot be synthesized from other metabolites in the human body. Among these are the three branched-chain amino acids (BCAAs): leucine (Leu), isoleucine (Ile), and valine (Val), so named because of their branched rather than linear aliphatic side chains.

May 10, 2013The disorder is prevented and treated dietary through eating of foods that are low in protein amounts to reduce excess production of ammonia in the body. Maple syrup urine disease (MSUD) is also another autosomal recessive disorder that affects amino acids that are branched. It is also called branched chain ketoaciduria.

Branched

Valine, leucine, and isoleucine are branched-chain amino acids; deficiency of enzymes involved in their metabolism leads to accumulation of organic acids with severe metabolic acidosis. There are numerous disorders of branched-chain amino acid metabolism (see Table ) as well as many other amino acid and organic acid metabolism disorders .

Branched

The branched-chain amino acids (BCAAs) namely valine, isoleucine and leucine are essential amino acids with hydrophobic side chains that comprise ∼20–40% of most dietary proteins (1,2). A large proportion of BCAAs from dietary sources is absorbed from the intestines, bypasses the liver, and is delivered to the peripheral tissues .

Diet Low in Branched

A specific group of amino acids called branched-chain amino acids (BCAAs) is elevated in the blood of obese, insulin-resistant humans and rodents. A new study in mice indicates that lowering consumption of BCAAs may combat the metabolic problems that occur in diabetes and obesity. The findings are published in the Journal of Physiology.

OBJECTIVE Recent studies using untargeted metabolomics approaches have suggested that plasma branched-chain amino acids (BCAAs) are associated with incident diabetes. However, little is known about the role of plasma BCAAs in metabolic abnormalities underlying diabetes and whether these relationships are consistent across ethnic populations at high risk for diabetes.

Disorders of Leucine, Isoleucine, and Valine Metabolism

Disorders in the catabolic pathways of the branched-chain amino acids (BCAA) leucine, isoleucine, and valine encompass diverse organic and aminoacidurias. Clinical severity may range from asymptomatic findings in some to life-threatening episodes and multiorgan involvement in others.

Amino Acid Disorders

DISORDERS OF AMINO ACID CATABOLISM Most of the known disorders of amino acid metabolism are disorders of amino acid catabolism. When an enzyme deficiency interferes with one of these pathways, a specific amino acid or amino acid by-product may accumulate to toxic levels. Of course, a deficiency of downstream products may also be detrimental.

DISORDERS OF AMINO ACID METABOLISM

They include the urea cycle disorders, in which the defect involves conversion of the amino group to urea, and many of the organic acidemias, which are caused by defects in the disposal of the carbon skeletons of the branched chain amino acids after the initial transamination step. With the exception of ornithine transcarbamylase deficiency, which is X-linked, all amino acid disorders are autosomal recessive.

Amino Acid Disorders

These metabolic disorders are caused by the body's inability to breakdown certain amino acids in proteins, or by the inability to detoxify the by-product of amino acids (ammonia) through the urea cycle. The buildup of amino acids and/or by-products of amino acid metabolism in the blood cause severe medical complications.
