Protein

Protein. Amino acid containing molecules encoded by genes. A nutritional component required by the body to sustain life. Protein is made up of amino acids that have been connected together in a variety of configurations depending on the type of protein. Whole food proteins are believed to play a role in Eosinophilic Enteritis. See also Amino Acid.

Introduction: Protein

Protein: A large molecule composed of one or more chains of amino acids in a specific order; the order is determined by the base sequence of nucleotides in the gene coding for the protein. Proteins are required for the structure, function, and regulation of the body’s cells, tissues, and organs, and each protein has unique functions. Examples are hormones, enzymes, and antibodies.

Introduction: Protein

Protein—A substance that determines the physical and chemical characteristics of a cell and therefore of an organism. Proteins are essential to all cell functions and are created using genetic information.

Proteins: Linear Polypeptides that are synthesized on Ribosomes and may be further modified, crosslinked, cleaved, or assembled into complex proteins with several subunits. The specific sequence of Amino Acids determines the shape the polypeptide will take, during Protein Folding, and the function of the protein.5

Protein: A group of complex organic macromolecules composed of one or more chains (linear polymers) of alpha-L-amino acids linked by peptide bonds and ranging in size from a few thousand to over 1 million Daltons. Proteins are fundamental genetically encoded components of living cells with specific structures and functions dictated by amino acid sequence.6
