Willardiine and Its Analogues
Willardiine was first identified by Rolf Gimelin in 1959 from the extracts of seeds of Acacia willardiana. Structurally it corresponds to (2S)-2-amino-3-(2,4-dioxopyrimidin-1-yl)propanoic acid (1) and carrying an uracil moiety it can be ascribed to the category of nucleoamino acids. Willardiine is synthesized by the single specific enzyme uracilylalanine synthase, and the N–heterocyclic moiety uracil obtained by the orotate pathway proved to be an effective bioisostere for the distal carboxyl group of L-glutamate. Different  aspects on both chemistry and biotechnological applications of willardine/willardine-analogues and nucleopeptides will be reviewed herein.

Will
Will, generally, is a faculty of the mind - within philosophy, will is important as one of the parts of the mind, along with reason and understanding. It is considered central to the field of ethics because of its role in enabling deliberate action. One of the recurring questions discussed in the Western philosophical tradition is that of free will - and the related, but more general notion of fate - which asks how the will can be truly free if a person's actions have either natural or divine causes which determine them. In turn, this is directly connected to discussions on the nature of freedom and to the problem of evil.
