FNDH 400: Ch. 2 "Macronutrients" questions and answers well illustrated. 1-2 sugar unit carbohydrates are called _____, while _____ carbohydrates contain more than 2 sugar units. - correct e, complex Which monosaccharide is not a 6 member ring? - glucose - galactose - fructose - correct ose Which monosaccharide is seldom found alone in nature? - glucose - galactose - fructose - correct tose (normally found in the disaccharide lactose) Which disaccharide contains a beta-bond? - maltose - sucrose - lactose - correct se Which of the following is not correct about monosaccharides or disaccharides? - Maltose = Glucose alpha-bonded to glucose - Sucrose = Glucose beta-bonded to fructose- Galactose and glucose are similar in structure - Lactose = Galactose beta-bonded to glucose - Fructose structure features a 5-member ring (pentose) - correct se High-fructose corn syrup contains the same monosaccharides as sucrose (glucose and fructose), which are free instead of part of a disaccharide, that will provide roughly the same amount of monosaccharides. (true or false) - correct Sugar alcohols, also called polyols and "sugar replacers," are a _____ option for chewing gums because they are _____ fermented by bacteria on surfaces of teeth. - correct , not Oldest artificial sweetener that develops a bitter taste when heated - correct arin Contains phenylalanine (a concern for those with PKU) and loses flavor when heated - correct tame Considered "aspartame 2.0" with an additional side group - correct me Newest and sweetest alternative sweetener - correct tame Provides no energy because it is not digested or absorbed. - correct lfame-potassium (K) Nearly identical to sucrose except 3 alcohol groups are replaced with chlorine molecules - correct lose "natural" alternative sweetener that is derived from a South American shrub's leaves - correct a "natural" alternative sweetener that is derived from extracts of a Chinese fruit which are sweet because of mogrosides - correct answers.Luo Hang Guo Oligosaccharides contain alpha _____ glycosidic bonds which are not digested and reach the colon. In the colon, bacteria _____ the oligosaccharides which leads to flatulence. Beano helps reduce flatulence because it contains a/n _____ (alpha-galactosidase) which is able to cleave this bond. - correct answers.1-6, ferment, enzyme Which of the following is not a polysaccharide? - Sugar - Most Fiber - Glycogen - Starch - correct The linear portions of both amylose and amylopectin are made of alpha 1-6 glycosidic bonds while the branches of amylopectin are made of alpha 1-4 glycosidic bonds. (true or false) - correct - linear portion: alpha 1-4 glycosidic bonds - alpha 1-6 glycosidic bonds. Glycogen is the storage form of carbohydrates in plants and starch is the storage form of glucose in animals. (true or false) - correct Glycogen is the storage form of carbohydrates in animals. Starch is the storage form of glucose in plants. Glycogen contains only alpha 1-6 glycosidic bonds, unlike amylopectin which contains both alpha 1-4 glycosidic bonds and alpha 1-6 glycosidic bonds. (true or false) - correct contains both type of bonds (1-4 & 1-6), like amylopectin What is true about sugar alcohols (polyols)? - correct answers.- Overall they are less sweet than sucrose - They are not fermented by bacteria in the mouth to a meaningful extent - They result in less acid produced than if sucrose was consumed - They provide less calories than sucrose Which of the following is a concern for those with PKU? - Tagatose - Saccharin - Aspartame - Acesulfame-K - Neotame - Advantame - correct tame Which of the alternative sweeteners might be able to be considered natural? - Sucralose - Advantame - Stevia - Aspartame - Luo Han Guo - correct a, Luo Han Guo Which of the following is not correct about oligosaccharides? - Contain few monosaccharides bonded together - Contain alpha 1-6 bonds - Are readily digested in the small intestine - Are fermented in the large intestine/colon - Fermentation can lead to flatulence - correct readily digested in the small intestine Which of the following is not a polysaccharide? - Glycogen - Starch - Most Fiber - Sugar - correct (is a mono- or disaccharide)
