What's the difference between albumin and protein?

Albumin


Definition:

  • (n.) A thick, viscous nitrogenous substance, which is the chief and characteristic constituent of white of eggs and of the serum of blood, and is found in other animal substances, both fluid and solid, also in many plants. It is soluble in water and is coagulated by heat and by certain chemical reagents.

  • (18) Because isosmolar albumin solution is easier to prepare than hyperosmolar cryoprecipitated plasma and gives comparable results, it remains our perfusate of choice for continuous perfusion preservation.
  • (19) We found that when neutrophils were allowed to settle into protein-coated surfaces the amount of O2- they generated varied with the nature of the protein: IgG greater than bovine serum albumin greater than plastic greater than gelatin greater than serum greater than collagen.
  • (20) The specificity of the assay was further demonstrated by a lack of competition of cytochrome C, myoglobin, epidermal growth factor or bovine serum albumin with bFGF for binding to the antibodies.

Protein


Definition:

  • (n.) A body now known as alkali albumin, but originally considered to be the basis of all albuminous substances, whence its name.

Example Sentences:

  • (1) All mutant proteins could associate with troponin I and troponin T to form a troponin complex.
  • (2) By electrophoresis and scanning densitometry, actin was found to constitute about 4% to 6% of the total cellular protein in the human corneal epithelium.

V. Shooter, G.H.
  • (7) Following central retinal artery ligation, infarction of the retinal ganglion cells was reflected by a 97 per cent reduction in the radioactively labeled protein within the optic nerve.
  • (8) Increased dietary protein intake led to increased MDA per nephron, increased urinary excretion of MDA, and increased MDA per milligram protein in subtotally nephrectomized animals, and markedly increased the glutathione redox ratio.
  • (9) The presence of O-glycosidic linkages between carbohydrate and protein in the DF3 antigenic site was further supported by the presence of NaBH4-sensitive sites.
  • (10) Cyclic AMP stimulated phosphorylation by [gamma-32P]ATP of two proteins of apparent Mr = 20,000 and 7,000 that were concentrated in sarcoplasmic reticulum, but the stimulation was markedly dependent on the presence of added soluble cyclic AMP-dependent protein kinase.
