What are the 6 carbon sugars?
The main monosaccharides are the hexoses (simple sugars in which the molecules contain six carbon atoms)—these include glucose (known also as dextrose), fructose1 (commonly called levulose), galactose, and mannose (Eliasson, 2016). All of which are naturally found in fruit juices.
What are the reaction of carbohydrates?
Reactions of Carbohydrates Carbohydrates are characterised by the reactions of the component functional groups: alcohols, aldehydes or ketones and acetals or ketals. Other reactions from earlier chapters that can be applied to carbohydrates included: Oxidative cleavage of 1,2-diols by periodate (HIO4)
What is carbohydrates and its classification?
Monosaccharides are simple sugars. They cannot be hydrolyzed into a simpler form. The simplest carbohydrates are the three carbon dihydroxyacetone and trioses glyceraldehyde. They are further classified into glucose, fructose, galactose, and mannose….1. Monosaccharides:
What sugar is the common hydrolysis product of higher carbohydrates?
Maltose, sometimes called malt sugar, comes from the hydrolysis of starch. It is about one third as sweet as cane sugar (sucrose), is easily digested by humans, and is fermented by yeast. Cellobiose is obtained by the hydrolysis of cellulose.
Where does the word oligomer come from in chemistry?
In chemistry and biochemistry, an oligomer ( / əˈlɪɡəmər / ( listen)) is a molecule that consists of a few similar or identical repeating units which could be derived, actually or conceptually, from copies of a smaller molecule, its monomer. The name is composed from Greek elements oligo-, “a few” and -mer, “parts”.
How are oligomers formed in a macromolecular complex?
Oligomer. In biochemistry, an oligomer usually refers to a macromolecular complex formed by non-covalent bonding of a few macromolecules like proteins or nucleic acids. In this sense, a homo-oligomer would be formed by few identical molecules and by contrast, a hetero-oligomer would be made of more than one, different, macromolecules.
Which is an example of a homo oligomeric protein?
Collagen is an example of a homo-oligomeric protein that is composed of three identical protein chains. The term multimer (/ˈmʌltɪmər/) (multi-, “more than one” + -mer, “part”) is used with a meaning similar to that of oligomer in the context of proteins (although technical restrictions of word sense may exist).
How are carbohydrates divided in a chemistry book?
The contents of the book are divided into two major parts, monomeric carbohydrates and oligosaccharides, with an introductory chapter discussing the historical background and significance of carbohydrates.
