Popis: Primates have stimulated more interest than any other group as humans are ranked in this same mammalian order. Gustatory responses of human and nonhuman primates have already been compared for compounds such as monosaccharides, oligosaccharides, polyols, amino acids, dipeptides, proteins, dihydrochalcones, sulfamates, saccharin, acesulfame, diterpenes or urea derivatives, all known to be sweet in man. But no rational comparison in primates has been attempted. Using a structure-activity relationship study in primates, it is now possible to classify the primate sweetness receptors into four types according to the behavioral responses observed from various selected compounds sweet in humans. The four types are represented by (1) the Callitrichidae and (2) the Cebidae, both from the infraorder Platyrrhini (New World monkeys), (3) the Lemuridae and Lorisidae, from the suborder Prosimii (prosimians), and (4) the Cercopithecidae (Old World monkeys), Hylobatidae (lesser apes), Pongidae (great apes), and Hominidae (humans) from the infraorder Catarrhini (Old World simians). By a comparative study of the putative receptor recognition sites postulated for each type of receptor, it is inferred that the Callitrichidae (marmosets and tamarins) have retained the most primitive sweetness receptor among primates. As we believe that the evolution of the sweetness receptor is a key factor involved in the raising of nonhuman primates from a ‘primitive grade’ towards a more ‘advanced’ or ‘simian grade,’ the possible phylogenetic implications of these findings will be discussed.
