https://www.ncbi.nlm.nih.gov/books/NBK537041/ Adiponectin (also known as AdipoQ or ACRP30) is a 244 amino acid monomer adipokine with a molecular weight of approximately 26 kDa. Adiponectin is the most abundant peptide hormone secreted by white adipocytes. Since discovering adiponectin in the 1990s, it has become a widely accepted biomarker for obesity-related diseases such as metabolic syndrome, Type 2 Diabetes mellitus, and atherosclerotic cardiovascular disease (ASCVD).[1][2] Adiponectin is present at high concentrations in plasma (3–30 μg/ml), which accounts for up to 0.05% of total serum protein.
