Unreferenced date September 2009 The Affix suffix ose is used in biochemistry to form the names of sugar s. Numerous systems exist to name specific sugars more descriptively. Monosaccharide s, the simplest sugars, may be named according to the number of carbon atoms in each molecule of the sugar pentose is a five carbon monosaccharide, and hexose is a six carbon monosaccharide. Aldehyde monosaccharides may be called aldose s ketone monosaccharides may be called ketose s. Larger sugars such as disaccharide s and polysaccharide s can be named to reflect their qualities. Lactose , a disaccharide found in milk , gets its name from the Latin word for milk combined with the sugar suffix its name means milk sugar . The polysaccharide that makes up plant starch is named amylose , or starch sugar see amyl Etymology . There are these theories about the origin of the ose suffix Extracted from glucose , an important hexose whose name came from Greek sweet . Extracted from sucrose , whose name came from Latin sucrum sugar plus the common Latin adjective forming suffix sus Latin sucrosus would mean sugary .
