adrenocorticotropic hormone definition: pituitary hormone that stimulates the secretion of adrenal cortical steroids and induces growth of the adrenal cortex.
Adrenocorticotropic Hormone definition: An anterior pituitary hormone that stimulates the ADRENAL CORTEX and its production of CORTICOSTEROIDS. ACTH is a 39-amino acid polypeptide of which the N-terminal 24-amino acid segment is identical in all species and contains the adrenocorticotrophic activity. Upon further tissue-specific processing, ACTH can yield ALPHA-MSH and corticotrophin-like intermediate lobe peptide (CLIP).
Adrenocorticotropic Hormone definition: A hormone secreted by the anterior portion of the pituitary gland and regulates hormone, primarily cortisol, secreted by the adrenal gland.
Peptides definition: Members of the class of compounds composed of AMINO ACIDS joined together by peptide bonds between adjacent amino acids into linear, branched or cyclical structures. OLIGOPEPTIDES are composed of approximately 2-12 amino acids. Polypeptides are composed of approximately 13 or more amino acids. PROTEINS are linear polypeptides that are normally synthesized on RIBOSOMES.
peptide definition: chemical bond with the structure -CO-CHR-NH-; in biochemistry, polymers of alpha-aminoacids joined by peptide bonds.
peptide definition: Any compound consisting of two or more amino acids, the building blocks of proteins. Peptides are combined to make proteins.
Peptide definition: A compound of two or more amino acids where the alpha carboxyl group of one is bound to the alpha amino group of another. Peptides are smaller than proteins and the dividing line is around 50 amino acids.
Aptamers, Peptide definition: Peptide sequences, generated by iterative rounds of SELEX APTAMER TECHNIQUE, that bind to a target molecule specifically and with high affinity.
