GLP1-S

Price range: $45.00 through $85.00

GLP1-S is a synthetic analog of glucagon-like peptide-1 (GLP-1), a hormone naturally produced in the intestines. It has a molecular weight of 4,113.64 g/mol and the formula C187H291N45O59 (CAS 910463-68-2). First described in 2007, it is classified as a GLP-1 receptor agonist. Key structural modifications include the substitution of alanine with alpha-aminoisobutyric acid (Aib) at position 8 and the attachment of a C-18 fatty diacid side chain at position 26, a modification common in long-acting peptide analogs. These structural differences distinguish GLP1-S from the native GLP-1 peptide. It appears as a white lyophilized powder that is soluble in water. This product is strictly for research purposes only.

Overview

GLP1-S is a synthetic analog of glucagon-like peptide-1 (GLP-1), a naturally occurring hormone produced in the intestines. Its molecular formula is C187H291N45O59, with a molecular weight of 4,113.64 g/mol (CAS 910463-68-2). First described in the scientific literature in 2007, it is classified as a GLP-1 receptor agonist — a synthetic analog structurally derived from the native GLP-1 peptide.

What distinguishes GLP1-S from the native hormone is a series of structural modifications. A key change is the substitution of alanine at position 8 with alpha-aminoisobutyric acid (Aib), a substitution that distinguishes it from the native GLP-1 sequence. Additionally, a C-18 fatty diacid chain is attached via a linker at position 26, a modification shared with other long-acting peptide analogs. These chemical changes distinguish GLP1-S structurally from the native 30-amino-acid GLP-1 peptide, which breaks down within minutes. In its research-grade form, GLP1-S appears as a white lyophilized powder that is soluble in water.
