Technical Specifications & Chemical Profile

Research Applications & Storage Protocols

mTOR Activation & Muscle Protein Synthesis Modulation Profile

HMB-Ca functions as a potent metabolite of the essential amino acid leucine, directly activating the mTOR (mechanistic target of rapamycin) pathway to stimulate ribosomal biogenesis and enhance muscle protein synthesis rates in in vitro myotube models. The compound inhibits the ubiquitin-proteasome system—the primary pathway for muscle protein degradation—by reducing caspase-3 activity and proteasome expression, thereby significantly decreasing muscle catabolism. HMB-Ca also modulates Akt/PKB signaling to promote anabolic conditions and has been shown to enhance wound healing through increased collagen deposition and fibroblast proliferation. These multi-target mechanisms position HMB-Ca as a critical tool compound for investigating sarcopenia mechanisms, exercise-induced hypertrophy research, age-related muscle loss models, HIV/AIDS-associated muscle wasting studies, and traumatic injury recovery pathways in preclinical models.

Handling & Storage Guidelines

• Long-Term Storage: Store desiccated at room temperature (15-25°C) in airtight conditions; avoid moisture exposure and high humidity environments

• Solubility: Soluble in water (moderate, ~10-20 mg/mL), DMSO (high); slightly soluble in ethanol; forms clear solutions in aqueous buffers

• Appearance: Fine white to off-white chalky crystalline powder with dry, bitter, slightly unpleasant taste and nondescript/chalky odor
