Phenylalanine molfidget with rotatable bonds

20 Amino Acid Molfidgets Collectionhttps://makerworld.com/collections/8398687 This is a molecular model of phenylalanine, created using molfidget. Phenylalanine is an essential amino acid that the body needs to get from food. It is used to build proteins and is also a precursor for important molecules like tyrosine, dopamine, norepinephrine, and epinephrine, which are involved in mood, alertness, and stress response. Because of its role in brain chemistry, phenylalanine is important for mental function and emotional balance. 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.
