4. In contrast to the alpha amino acids which are ubiquitous in nature, beta amino acids (with an extra carbon in the backbone) are quite rare. They form secondary structures that have very different conformations from traditional proteins. For instance, the compound shown below is the simplest beta amino acid; unusually, it is most stable in a gauche conformation. Draw it and explain why, co, Corn lonic c Hdi athrachan H₂N HT 5. Quebrachitol is a naturally occurring compound found...
