Serum albumin
(gcide) | Serum \Se"rum\ (s[=e]"r[u^]m), n. [L., akin to Gr. ???, Skr.
s[=a]ra curd.] (Physiol.)
(a) The watery portion of certain animal fluids, as blood,
milk, etc.
(b) A thin watery fluid, containing more or less albumin,
secreted by the serous membranes of the body, such as the
pericardium and peritoneum.
[1913 Webster]
Blood serum, the pale yellowish fluid which exudes from the
clot formed in the coagulation of the blood; the liquid
portion of the blood, after removal of the blood
corpuscles and the fibrin.
Muscle serum, the thin watery fluid which separates from
the muscles after coagulation of the muscle plasma; the
watery portion of the plasma. See Muscle plasma, under
Plasma.
Serum albumin (Physiol. Chem.), an albuminous body, closely
related to egg albumin, present in nearly all serous
fluids; esp., the albumin of blood serum.
Serum globulin (Physiol. Chem.), paraglobulin.
Serum of milk (Physiol. Chem.), the whey, or fluid portion
of milk, remaining after removal of the casein and fat.

(gcide) | Protein \Pro"te*in\, n. [Gr. prw^tos first: cf. prwtei^on the
first place.] (Physiol. Chem.)
any polymer of an amino acid joined by peptide (amide) bonds.
Most natural proteins have alpha-amino acids as the monomeric
constituents. All classical enzymes are composed of protein,
and control most of the biochemical transformations carrie
dout in living cells. They may be soluble, as casein,
albumins, and other globular proteins, or insoluble (e. g.
"structural proteins"), as collagen or keratin. "albumin", an
older term for protein, is now used primarily to refer to
certain specific soluble globular proteins found in eggs or
blood serum, e.g. bovine serum albumin, the main soluble
protein in teh serum of cattle, used as an enzymatically
inert protein in biochemical research.
Note: In the 1913 dictionary, protein was defined as: "A body
now known as alkali albumin, but originally considered
to be the basis of all albuminous substances, whence
its name."
