What is a common property of glucose, galactose, and fructose?<\/p>\n\n\n\n
a) They can all form six-membered rings <\/p>\n\n\n\n
b) They are all aldoses <\/p>\n\n\n\n
c) They have the same chemical formula <\/p>\n\n\n\n
d) They can form the trisaccharide lactose<\/p>\n\n\n\n
The correct answer and explanation is:<\/mark><\/strong><\/p>\n\n\n\n Correct Answer: c) They have the same chemical formula<\/strong><\/p>\n\n\n\n Glucose, galactose, and fructose are all monosaccharides, which are the simplest form of carbohydrates. A common property shared among them is that they all have the same chemical formula<\/strong>, C\u2086H\u2081\u2082O\u2086<\/strong>. This means they are isomers<\/strong> of each other. Even though they have the same number and types of atoms, the arrangement of these atoms in space is different, giving each sugar unique structural and chemical properties.<\/p>\n\n\n\n Glucose and galactose are aldoses<\/strong>, meaning they contain an aldehyde group<\/strong> (-CHO) at the end of their carbon chain. Fructose, on the other hand, is a ketose<\/strong>, containing a ketone group<\/strong> (C=O) typically on the second carbon atom. This difference rules out option (b), since fructose is not an aldose.<\/p>\n\n\n\n Option (a) is also incorrect because although glucose and galactose can form six-membered rings known as pyranose rings<\/strong>, fructose typically forms a five-membered furanose ring<\/strong> in solution, although it can occasionally form a six-membered ring under certain conditions.<\/p>\n\n\n\n Option (d) is incorrect because lactose<\/strong> is a disaccharide<\/strong>, not a trisaccharide. It is formed by the combination of glucose and galactose only. Fructose does not take part in forming lactose. Instead, fructose commonly forms disaccharides like sucrose<\/strong> (with glucose).<\/p>\n\n\n\n In conclusion, the shared feature among glucose, galactose, and fructose is their identical molecular formula<\/strong>, which categorizes them as structural isomers<\/strong>. This commonality underlines how molecules can have the same composition but different structures and functions, a key concept in organic and biological chemistry.<\/p>\n","protected":false},"excerpt":{"rendered":" What is a common property of glucose, galactose, and fructose? a) They can all form six-membered rings b) They are all aldoses c) They have the same chemical formula d) They can form the trisaccharide lactose The correct answer and explanation is: Correct Answer: c) They have the same chemical formula Glucose, galactose, and fructose […]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-34452","post","type-post","status-publish","format-standard","hentry","category-quiz-questions"],"_links":{"self":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/34452","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/comments?post=34452"}],"version-history":[{"count":1,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/34452\/revisions"}],"predecessor-version":[{"id":34453,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/34452\/revisions\/34453"}],"wp:attachment":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/media?parent=34452"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/categories?post=34452"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/tags?post=34452"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
