Circular Dichroism of Amino Acids: Following the Structural Formation of Phenylalanine.

摘要: Circular dichroism (CD) is frequently used to assess the secondary structure of peptides and proteins, whereas less attention has been given their building blocks, that is, single amino acids, as they do not possess a structure. Here, we follow CD signal acids reveal several exhibit unique pattern function concentration. Accordingly, propose an eight-level classification various acids. Special focus phenylalanine (Phe), for which observe formation ultra-narrow peak (full width at high maximum only 5 nm). This can be attributed Phe-based chiral structural features. Further support ordered by using NMR, additional self-assembly process Phe tubular structures.
