Which amino acid has no free alpha amino group?

Proline is the amino acid that does not have a free alpha amino group in its side chain. This is because proline's side chain cyclizes back to the amino group, forming a unique structure that lacks a free alpha amino group.

What is a beta-amino acid?

A beta-amino acid is a type of amino acid where the amino group is located on the beta carbon, rather than the alpha carbon, as seen in traditional amino acids. They are less common than alpha-amino acids but possess unique chemical and biological properties. Beta-amino acids can be found in certain natural products and have potential applications in drug development and materials science.

What characteristics of a molecule make it an amino acid?

Being both an amine and an acid, of course.Generally the term is used mainly for a specific type of amino acids... alpha-amino carboxylic acids. However, taurine is also called an amino acid, despite the fact that it's a sulfonic acid rather than a carboxylic acid.(alpha-amino means the amine group is attached to the first carbon after the carboxylic acid carbon itself. In taurine, the amine group is attached to the second carbon after the sulfonic acid group.)
