Carlos Eugenio Cardini Bellati, Argentine biochemist (Buenos Aires 09 December 1911 – Buenos Aires 10 August 1992) From Italian grandparents With R. Caputto, L.F. Leloir and A. Paladini discovered sugar nucleotides, determined its chemical nature and showed that play a key role in sugar interconversion and polysaccharides synthesis (1948) With L.F. Leloir established that in plant tissues two reactions can lead to synthesis of sucrose (1953-5) With L.F. Leloir suggested the involvement of uridine diphosphate N-acetylglucosamine in chitin synthesis (1953) With L.F. Leloir and J. Chiriboga synthesized sucrose (1955) With L.F. Leloir described an alternative mechanism for synthesis of glycogen from UDP-glucose and glycogen synthase (1957) With Yamaha & Leloir demonstrated that glycosides synthesis via UDPG (1960) With Fekete & Leloir discovered enzymatic system that catalyzes sucrose transformation into starch (1960) With Rosalía B. de Frydman & Luis F.
