beta-endorphin
beta-Endorphin: A 31-amino acid peptide that is the C-terminal fragment of BETA-LIPOTROPIN. It acts on OPIOID RECEPTORS and is an analgesic. Its first four amino acids at the N-terminal are identical to the tetrapeptide sequence of METHIONINE ENKEPHALIN and LEUCINE ENKEPHALIN.. beta-endorphin : A polypeptide consisting of 31 amino acid residues in the sequence Tyr-Gly-Gly-Phe-Met-Thr-Ser-Glu-Lys-Ser-Gln-Thr-Pro-Leu-Val-Thr-Leu-Phe-Lys-Asn-Ala-Ile-Ile-Lys-Asn-Ala-Tyr-Lys-Lys-Gly-Glu. It is an endogenous opioid peptide neurotransmitter found in the neurons of both the central and peripheral nervous system and results from processing of the precursor protein proopiomelanocortin (POMC). | 2.6 | 1 | 0 | | |
exenatide
Exenatide: A synthetic form of exendin-4, a 39-amino acid peptide isolated from the venom of the Gila monster lizard (Heloderma suspectum). Exenatide increases CYCLIC AMP levels in pancreatic acinar cells and acts as a GLUCAGON-LIKE PEPTIDE-1 RECEPTOR (GLP-1) agonist and incretin mimetic, enhancing insulin secretion in response to increased glucose levels; it also suppresses inappropriate glucagon secretion and slows gastric emptying. It is used an anti-diabetic and anti-obesity agent. | 2.1 | 1 | 0 | | |
ascorbic acid
Ascorbic Acid: A six carbon compound related to glucose. It is found naturally in citrus fruits and many vegetables. Ascorbic acid is an essential nutrient in human diets, and necessary to maintain connective tissue and bone. Its biologically active form, vitamin C, functions as a reducing agent and coenzyme in several metabolic pathways. Vitamin C is considered an antioxidant.. L-ascorbic acid : The L-enantiomer of ascorbic acid and conjugate acid of L-ascorbate.. L-ascorbate : The L-enantiomer of ascorbate and conjugate base of L-ascorbic acid, arising from selective deprotonation of the 3-hydroxy group. Required for a range of essential metabolic reactions in all animals and plants.. vitamin C : Any member of a group of vitamers that belong to the chemical structural class called butenolides that exhibit biological activity against vitamin C deficiency in animals. The vitamers include L-ascorbic acid and its salt, ionized and oxidized forms. | 2 | 1 | 0 | ascorbic acid;
