Exenatide binds to the intact human Glucagon-like peptide-1 receptor (GLP-1R) in a similar way to the human peptide glucagon-like peptide-1 (GLP-1); exenatide bears a 50% amino acid homology to GLP-1 and it has a longer half-life in vivo. [22] Exenatide is believed to facilitate glucose control in at least five ways:
Insulin degludec is a modified insulin that has one single amino acid deleted in comparison to human insulin, and is conjugated to hexadecanedioic acid via gamma-L-glutamyl spacer at the amino acid lysine at position B29. It is included on the World Health Organization's List of Essential Medicines [11] as an equivalent to insulin glargine.
Insulin-treated athletes are perceived to have lean body mass because physiological hyperinsulinemia in human skeletal muscle improves the activity of amino acid transport, which in turn promotes protein synthesis. [78] Insulin stimulates the transport of amino acids into cells and also controls glucose metabolism.
Insulin glulisine, sold under the brand name Apidra among others, is a rapid-acting modified form of medical insulin used for the treatment of diabetes.It differs from human insulin in that the amino acid asparagine at position B3 is replaced by lysine and the lysine in position B29 is replaced by glutamic acid.

The amino acid sequence of animal insulins in different mammals may be similar to human insulin (insulin human INN), there is however considerable viability within vertebrate species. [16] Porcine insulin has only a single amino acid variation from the human variety, and bovine insulin varies by three amino acids.
Long-term effects are unknown. SAM is a weak DNA-alkylating agent. [25] Another reported side effect of SAM is insomnia; therefore, the supplement is often taken in the morning. Other reports of mild side effects include lack of appetite, constipation, nausea, dry mouth, sweating, and anxiety/nervousness, but in placebo-controlled studies ...
The organic compound citrulline is an α-amino acid. [2] Its name is derived from citrullus, the Latin word for watermelon.Although named and described by gastroenterologists since the late 19th century, it was first isolated from watermelon in 1914 by Japanese researchers Yatarō Koga (古賀彌太郎) and Ryō Ōtake (大嶽了) [3] [4] and further codified by Mitsunori Wada of Tokyo ...
Amino acid sequence of amylin with disulfide bridge and cleavage sites of insulin degrading enzyme indicated with arrows. Amylin, or islet amyloid polypeptide (IAPP), is a 37-residue peptide hormone. [5] It is co-secreted with insulin from the pancreatic β-cells in the ratio of approximately 100:1 (insulin:amylin).
