Amino acids and peptides are fundamental components of living organisms. Together, they form part of the molecular framework that supports countless biological processes, from cellular communication to enzyme activity and hormone signalling. Scientists have studied amino acids and peptides for decades because understanding how they interact provides valuable insight into molecular biology, physiology and biochemistry....Read More

Retatrutide and tirzepatide are active pharmaceutical compounds that have attracted significant interest within scientific and medical research. Although they are often discussed together, they are distinct molecules with different pharmacological characteristics. This article provides an educational overview of how they differ. What Is Tirzepatide? Tirzepatide is an active pharmaceutical ingredient that interacts with two naturally...Read More

Mitochondria were once viewed primarily as structures responsible for producing cellular energy. That view has changed dramatically. Researchers now know that mitochondria participate in signalling, cellular stress responses and communication with other parts of the cell. One particularly interesting discovery has been a family of molecules known as mitochondrial-derived peptides, or MDPs. Among them is...Read More

Mitochondria are normally described as the energy-producing structures inside our cells. But modern research has revealed something considerably more interesting. Mitochondria don’t simply produce energy. They can also produce biologically active signalling peptides. These molecules are known as mitochondrial-derived peptides, or MDPs, and they have opened an entirely new area of research into cellular stress,...Read More

The next generation of metabolic research may not rely entirely on activating receptors with peptides. Scientists are now investigating something fundamentally different: silencing a gene in the liver to change metabolic signalling throughout the body. One of the most interesting emerging targets is INHBE. INHBE produces a signalling protein called Activin E, which has become...Read More

Most discussions about modern metabolic research eventually come back to hormones such as GLP-1, GIP, glucagon or amylin. But appetite regulation doesn’t begin and end in the gastrointestinal system. Deep within the brain is another important signalling network known as the melanocortin pathway. At the centre of this system is the melanocortin-4 receptor, usually abbreviated...Read More

Multi-receptor metabolic research is moving into increasingly sophisticated territory. Researchers have already developed compounds combining GLP-1 with GIP, glucagon and amylin-related pathways. Now another signalling system is entering the picture: Neuropeptide Y. BI 3034701 is an investigational compound developed by Boehringer Ingelheim that combines activity at three receptors: GLP-1 GIP and NPY2. The compound entered...Read More

GLP-1, GIP, glucagon and amylin dominate much of today’s discussion around metabolic research. But another signalling system is attracting increasing scientific attention: GDF15 and its receptor GFRAL. Growth differentiation factor 15 — usually shortened to GDF15 — is a stress-responsive signalling protein whose biology is very different from traditional incretin hormones. Researchers are investigating its...Read More

Most modern metabolic compounds have been developed around appetite, incretin hormones or energy regulation. Bimagrumab takes a fundamentally different approach. Rather than targeting GLP-1,...Read More

The next major question in metabolic research may not simply be how much body weight changes. Researchers are increasingly asking: What type of tissue is actually being lost? Changes in total body weight can involve both fat mass and lean body mass. This has created growing scientific interest in strategies designed to preserve skeletal muscle...Read More
