Robayo-Torres C, Diaz-Sotomayor M, Hamaker B, Baker S, Chumpitazi B, Opekun A, et al.
J Pediatr Gastroenterol Nutr . 2018 May; 66 Suppl 3:S61-S64. PMID: 29762381
Background And Hypotheses: Human starch digestion is a multienzyme process involving 6 different enzymes: salivary and pancreatic α-amylase; sucrase and isomaltase (from sucrose-isomaltase [SI]), and maltase and glucoamylase (from maltase-glucoamylase...

J Pediatr Gastroenterol Nutr . 2018 May; 66 Suppl 3:S52-S55. PMID: 29762379
Background: A subset of children with functional gastrointestinal disorders (FGIDs), which includes functional dyspepsia, may have duodenal disaccharidase deficiencies. Objectives: To determine the frequency, demographics, and clinical characteristics associated with...

Robayo-Torres C, Opekun A, Quezada-Calvillo R, Villa X, Smith E, Navarrete M, et al.
J Pediatr Gastroenterol Nutr . 2009 Mar; 48(4):412-8. PMID: 19330928
Background: Congenital sucrase-isomaltase deficiency (CSID) is characterized by absence or deficiency of the mucosal sucrase-isomaltase enzyme. Specific diagnosis requires upper gastrointestinal biopsy with evidence of low to absent sucrase enzyme...

Nichols B, Quezada-Calvillo R, Robayo-Torres C, Ao Z, Hamaker B, Butte N, et al.
J Nutr . 2009 Feb; 139(4):684-90. PMID: 19193815
Starch is the major source of food glucose and its digestion requires small intestinal alpha-glucosidic activities provided by the 2 soluble amylases and 4 enzymes bound to the mucosal surface...

Quezada-Calvillo R, Sim L, Ao Z, Hamaker B, Quaroni A, Brayer G, et al.
J Nutr . 2008 Mar; 138(4):685-92. PMID: 18356321
The detailed mechanistic aspects for the final starch digestion process leading to effective alpha-glucogenesis by the 2 mucosal alpha-glucosidases, human sucrase-isomaltase complex (SI) and human maltase-glucoamylase (MGAM), are poorly understood....

Quezada-Calvillo R, Robayo-Torres C, Ao Z, Hamaker B, Quaroni A, Brayer G, et al.
J Pediatr Gastroenterol Nutr . 2007 Jun; 45(1):32-43. PMID: 17592362
Background: Starches are the major source of dietary glucose in weaned children and adults. However, small intestine alpha-glucogenesis by starch digestion is poorly understood due to substrate structural and chemical...

Quezada-Calvillo R, Robayo-Torres C, Opekun A, Sen P, Ao Z, Hamaker B, et al.
J Nutr . 2007 Jun; 137(7):1725-33. PMID: 17585022
Digestion of starch requires activities provided by 6 interactive small intestinal enzymes. Two of these are luminal endo-glucosidases named alpha-amylases. Four are exo-glucosidases bound to the luminal surface of enterocytes....
