Arginine molfidget with rotatable bonds

20 Amino Acid Molfidgets Collectionhttps://makerworld.com/collections/8398687 This is a molecular model of arginine, created using molfidget. Arginine is a conditionally essential amino acid — the body can usually make it, but during times of stress, illness, or growth, extra amounts may be needed from the diet. Arginine plays a key role in producing nitric oxide, a molecule that widens blood vessels and improves circulation. It also supports wound healing, immune function, hormone release, and detoxification through the urea cycle. 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.
