- Avian proteins
Amphibian
Amphibians are ectothermic, anamniotic, four-limbed vertebrate animals that constitute the class Amphibia.
Antibiotic
An antibiotic is a type of antimicrobial substance active against bacteria.
Antibody
An antibody (Ab) is the secreted form of a B cell receptor; the term immunoglobulin (Ig) can refer to either the membrane-bound form or the secreted form of the B cell receptor, but they are, broadly speaking, the same protein, and so the terms are often treated as synonymous. Avidin and antibody are Glycoproteins.
Antinutrient
Antinutrients are natural or synthetic compounds that interfere with the absorption of nutrients.
Assay
An assay is an investigative (analytic) procedure in laboratory medicine, mining, pharmacology, environmental biology and molecular biology for qualitatively assessing or quantitatively measuring the presence, amount, or functional activity of a target entity.
See Avidin and Assay
Biochemical and Biophysical Research Communications
Biochemical and Biophysical Research Communications is a weekly peer-reviewed scientific journal covering all aspects of biochemistry and biophysics.
See Avidin and Biochemical and Biophysical Research Communications
Biotin
Biotin (also known as vitamin B7 or vitamin H) is one of the B vitamins.
Biotinylation
In biochemistry, biotinylation is the process of covalently attaching biotin to a protein, nucleic acid or other molecule.
Bird
Birds are a group of warm-blooded vertebrates constituting the class Aves, characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton.
See Avidin and Bird
Carbohydrate
A carbohydrate is a biomolecule consisting of carbon (C), hydrogen (H) and oxygen (O) atoms, usually with a hydrogen–oxygen atom ratio of 2:1 (as in water) and thus with the empirical formula (where m may or may not be different from n), which does not mean the H has covalent bonds with O (for example with, H has a covalent bond with C but not with O).
D-value (microbiology)
In microbiology, in the context of a sterilization procedure, the D-value or decimal reduction time (or decimal reduction dose) is the time (or dose of an antimicrobial drug) required, at a given condition (e.g. temperature) or set of conditions, to achieve a one-log reduction, that is, to kill 90% of relevant microorganisms.
See Avidin and D-value (microbiology)
Dalton (unit)
The dalton or unified atomic mass unit (symbols: Da or u) is a non-SI unit of mass defined as of the mass of an unbound neutral atom of carbon-12 in its nuclear and electronic ground state and at rest.
Denaturation (biochemistry)
In biochemistry, denaturation is a process in which proteins or nucleic acids lose folded structure present in their native state due to various factors, including application of some external stress or compound, such as a strong acid or base, a concentrated inorganic salt, an organic solvent (e.g., alcohol or chloroform), agitation and radiation, or heat.
See Avidin and Denaturation (biochemistry)
Dissociation constant
In chemistry, biochemistry, and pharmacology, a dissociation constant (KD) is a specific type of equilibrium constant that measures the propensity of a larger object to separate (dissociate) reversibly into smaller components, as when a complex falls apart into its component molecules, or when a salt splits up into its component ions.
See Avidin and Dissociation constant
Egg
An egg is an organic vessel grown by an animal to carry a possibly fertilized egg cell (a zygote) and to incubate from it an embryo within the egg until the embryo has become an animal fetus that can survive on its own, at which point the animal hatches.
See Avidin and Egg
Egg white
Egg white is the clear liquid (also called the albumen or the glair/glaire) contained within an egg.
ELISA
The enzyme-linked immunosorbent assay (ELISA) is a commonly used analytical biochemistry assay, first described by Eva Engvall and Peter Perlmann in 1971.
See Avidin and ELISA
ELISpot
The enzyme-linked immunosorbent spot (ELISpot) is a type of assay that focuses on quantitatively measuring the frequency of cytokine secretion for a single cell.
Esmond Emerson Snell
Esmond Emerson Snell (September 22, 1914 – December 9, 2003) was an American biochemist who spent his career researching vitamins and nutritional requirements of bacteria and yeast.

Glycosylation
Glycosylation is the reaction in which a carbohydrate (or 'glycan'), i.e. a glycosyl donor, is attached to a hydroxyl or other functional group of another molecule (a glycosyl acceptor) in order to form a glycoconjugate.
Heparin
Heparin, also known as unfractionated heparin (UFH), is a medication and naturally occurring glycosaminoglycan.
Immunoprecipitation
Immunoprecipitation (IP) is the technique of precipitating a protein antigen out of solution using an antibody that specifically binds to that particular protein.
See Avidin and Immunoprecipitation
Isoelectric point
The isoelectric point (pI, pH(I), IEP), is the pH at which a molecule carries no net electrical charge or is electrically neutral in the statistical mean.
See Avidin and Isoelectric point
Journal of Food Science
The Journal of Food Science is a peer-reviewed scientific journal that was established in 1936 and is published by John Wiley & Sons on behalf of the Institute of Food Technologists in Chicago, Illinois.

Mannose
Mannose is a sugar monomer of the aldohexose series of carbohydrates.
Meir Wilchek
Meir Wilchek (Hebrew: מאיר אשר וילצ'ק, born 17 October 1935) is an Israeli biochemist.
N-Acetylglucosamine
N-Acetylglucosamine (GlcNAc) is an amide derivative of the monosaccharide glucose.

Oligosaccharide
An oligosaccharide is a saccharide polymer containing a small number (typically three to ten) of monosaccharides (simple sugars).

Oviduct
The oviduct in vertebrates is the passageway from an ovary.
Protein
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues.
Protein Data Bank
The Protein Data Bank (PDB) is a database for the three-dimensional structural data of large biological molecules such as proteins and nucleic acids, which is overseen by the Worldwide Protein Data Bank (wwPDB).

Protein dimer
In biochemistry, a protein dimer is a macromolecular complex or multimer formed by two protein monomers, or single proteins, which are usually non-covalently bound.
Protein subunit
In structural biology, a protein subunit is a polypeptide chain or single protein molecule that assembles (or "coassembles") with others to form a protein complex.
