  2. Elevated transaminases - Wikipedia

    en.wikipedia.org/wiki/Elevated_transaminases

    Muscle sources of the enzymes, such as intense exercise, are unrelated to liver function and can markedly increase AST and ALT. [5] Cirrhosis of the liver or fulminant liver failure secondary to hepatitis commonly reach values for both ALT and AST in the >1000 U/L range; however, many people with liver disease have normal transaminases.

  3. Liver function tests - Wikipedia

    en.wikipedia.org/wiki/Liver_function_tests

    Liver function tests (LFTs or LFs), also referred to as a hepatic panel or liver panel, are groups of blood tests that provide information about the state of a patient's liver. [1] These tests include prothrombin time (PT/INR), activated partial thromboplastin time (aPTT), albumin , bilirubin (direct and indirect), and others.

  4. AST/ALT ratio - Wikipedia

    en.wikipedia.org/wiki/AST/ALT_ratio

    The proportion of AST to ALT in hepatocytes is about 2.5:1, but because AST is removed from serum by the liver sinusoidal cells twice as quickly (serum half-life t 1/2 = 18 hr) compared to ALT (t 1/2 = 36 hr), so the resulting serum levels of AST and ALT are about equal in healthy individuals, resulting in a normal AST/ALT ratio around 1.

  5. Alanine transaminase - Wikipedia

    en.wikipedia.org/wiki/Alanine_transaminase

    Alanine transaminase (ALT), also known as alanine aminotransferase (ALT or ALAT), formerly serum glutamate-pyruvate transaminase (GPT) or serum glutamic-pyruvic transaminase (SGPT), is a transaminase enzyme (EC 2.6.1.2) that was first characterized in the mid-1950s by Arthur Karmen and colleagues. [1]

  6. Transaminase - Wikipedia

    en.wikipedia.org/wiki/Transaminase

    The transaminase enzymes are important in the production of various amino acids, and measuring the concentrations of various transaminases in the blood is important in the diagnosing and tracking many diseases. [citation needed] For example, the presence of elevated transaminases can be an indicator of

  7. Proteins produced and secreted by the liver - Wikipedia

    en.wikipedia.org/wiki/Proteins_produced_and...

    All plasma proteins except Gamma-globulins are synthesised in the liver. [1] Human serum albumin, osmolyte and carrier protein; α-fetoprotein, the fetal counterpart of serum albumin; Soluble plasma fibronectin, forming a blood clot that stops bleeding; C-reactive protein, opsonin on microbes, [2] acute phase protein; Various other globulins

  8. Hepatic lipase - Wikipedia

    en.wikipedia.org/wiki/Hepatic_lipase

    The activation of HL occurs in two steps. First, HDL that makes its way to the liver, binds to HL thereby removing the heparan sulfate proteoglycan and freeing up the hepatic lipase into the bloodstream, but HL is still inactive due to the proteins on the surface of the lipoprotein. Second, HDL unbinds from HL to activate HL enzymes in the ...

  9. Carboxylesterase 1 - Wikipedia

    en.wikipedia.org/wiki/Carboxylesterase_1

    Liver carboxylesterase 1 also known as carboxylesterase 1 (CES1, hCE-1 or CES1A1) is an enzyme that in humans is encoded by the CES1 gene. [ 5 ] [ 6 ] The protein is also historically known as serine esterase 1 (SES1), monocyte esterase and cholesterol ester hydrolase (CEH).
