<h3>Carmin (~300kDa) shown as two &#39;stacked&#39; trimers. Each monomer consists of two subunits (acidic and basic) linked two by disulfide bonds (between 2 cysteine residues). The monomers are packed into a hexamer structure through non-covalent bonds such as hydrogen bonding, hydrophobic interactions and van der Waals forces.</h3>
