Beta Amino Acids: Definition & Examples

AI Thread Summary
Beta amino acids are defined by having the amino group attached to the beta carbon, which is the second carbon from the functional group. An example of a beta amino acid is 3-aminopropionic acid, commonly known as beta-alanine, the only naturally occurring beta amino acid formed from the degradation of di-peptides. The structure of beta-alanine includes an additional CH2 group between the amino and carboxyl groups. Understanding the arrangement of functional groups in beta amino acids is crucial for grasping their chemical properties. This discussion clarifies the structural characteristics and examples of beta amino acids.

What is a beta amino acid and how would a beta amino acid look like?

I know that the beta carbon is the second carbon from the functional group but which group would be where? Can I have an example of a beta amino acid?

3-aminopropionic acid is an example of a beta amino acid, more commonly know as beta-alanine. As far as I know this is the only naturally occurring beta amino acid and is formed by the degredation of di-peptides.
 
what is the structure formula for that example? How are the functional groups arranged in a beta amino acid?

Oh now I get it! There can be another CH_2 group in the middle! It helped alot. Thank you.
 

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
