I'm having a hard time understanding why my slides in my biology course have two different representations of the "basic structure" of the amino acid:
The top one seem like what I would expect. The bottom one, it looks like the amine group gained a Hydrogen ion and the Carboxyl group lost one. Also, the center carbon gained an H. I honestly don't know if this description is even correct or not.
I'm extremely new to this level of biology, so very simple explanations are much appreciated. I just don't totally understand why there are two versions of the basic structure.
Also, I apologize if the tag is wrong, again, this isn't my major, so I'm very new to this material.
