In a refinement based approach it is beneficial to model systems . abstractly . with . little architectural structure .

The term ‘absolute structure’ is a generalisation of the term ‘absolute configuration’ of objects such as molecules or crystals without an inversion centre or mirror plane. The concept also includes ‘absolute polarity’ of an object or crystal.. Papain-like Cysteine Protease . from the . Bulbs . of . Crocus . sativus . Dr. Sadaf . Iqbal. 4/29/2014. 1. DR.
