Histidine molfidget with rotatable bonds

20 Amino Acid Molfidgets Collectionhttps://makerworld.com/collections/8398687 This is a molecular model of histidine, created using molfidget. Histidine is a semi-essential amino acid, meaning it is especially important during growth or recovery. It is used to build proteins and plays a crucial role in the immune system, tissue repair, and the production of histamine, a molecule involved in immune response, digestion, and sleep regulation. Histidine also helps maintain pH balance in the body by acting as a buffer.In this model, all single bonds are rotatable. Some carbon atoms are pre-connected, and you can complete the assembly by manually attaching the remaining atoms.
