Summary
Liver disease alters plasma amino acid levels, with methionine increasing and branched-chain amino acids decreasing in chronic conditions. Minimal liver disease also shows reduced branched-chain amino acids and proline.
Area of Science:
- Biochemistry
- Hepatology
- Clinical Nutrition
Background:
- Plasma amino acid profiles can reflect liver function.
- Altered amino acid metabolism is associated with various liver diseases.
Purpose of the Study:
- To investigate plasma amino acid concentrations in patients with diverse liver diseases.
- To compare these concentrations with those in healthy controls.
- To explore potential correlations between amino acid changes and liver disease severity/type.
Main Methods:
- Measured plasma amino acid concentrations in 167 patients with liver disease and 57 controls.
- Categorized patients based on liver disease aetiology and severity.
- Utilized statistical analysis to compare amino acid levels between groups.
Main Results:
- Chronic liver disease showed increased methionine and reduced branched-chain amino acids.
- Specific amino acid changes varied by liver disease type (e.g., alcoholic hepatitis vs. biliary cirrhosis).
- Minimal liver disease exhibited reduced proline and branched-chain amino acids.
Conclusions:
- Plasma amino acid alterations are indicative of liver dysfunction, portal-systemic shunting, and hormonal imbalances.
- Observed changes in chronic liver disease are largely attributable to impaired hepatic function.
- The mechanisms behind amino acid changes in minimal liver disease require further investigation.

In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess...

01:29Amino Acid Biosynthetic Pathways
1.4K
Amino acid biosynthesis is essential for cell growth, protein synthesis, and metabolic regulation. Cells generate essential and non-essential amino acids from metabolic intermediates to sustain vital biological functions. These intermediates originate from key metabolic pathways: glycolysis, the tricarboxylic acid (TCA) cycle, and the pentose phosphate pathway. Important precursors include α-ketoglutarate, pyruvate, oxaloacetate, phosphoenolpyruvate, and erythrose-4-phosphate, which...

01:18Amino Acid Catabolism
1.3K
Microorganisms rely on proteins as an essential carbon and energy source, particularly in environments with limited polysaccharides or lipids. However, proteins are too large to cross the plasma membrane unaided, necessitating enzymatic degradation. Microbes secrete extracellular proteases and peptidases that hydrolyze proteins into peptides, which can then be transported across the membrane. Once inside the cell, intracellular proteases degrade these peptides into free amino acids, which...

Amino acids are the monomers that comprise proteins. Each amino acid has the same fundamental structure, which consists of a central carbon atom, or the alpha (α) carbon, bonded to an amino group (NH2), a carboxyl group (COOH), and to a hydrogen atom. Every amino acid also has another atom or group of atoms bonded to the central atom known as the R group. There are 20 common amino acids present in proteins, each with a different R group. Variation in the amino acid sequence is responsible for...

Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...

01:19Phase II Reactions: Sulfation and Conjugation with α-Amino Acids
1.0K
Sulfation and α-amino acid conjugation are two critical biotransformation reactions in drug metabolism. Sulfation, a phase II biotransformation reaction, involves adding a polar sulfate group to a drug, enhancing its water solubility and promoting excretion. This process can either co-occur with or occur independently of glucuronidation. Nonmicrosomal sulfotransferase enzymes catalyze the process. The reaction involves 3'-phosphoadenosine-5'-phosphosulfate or PAPS coenzyme...
