What are sugars with 5 carbons called?
What are sugars with 5 carbons called?
Ribose is a single-ring pentose [5-Carbon] sugar. The numbering of the carbon atoms runs clockwise, following organic chemistry rules.
What is the most common 5 carbon sugar?
The most abundant five-carbon sugars are L-arabinose, D-ribose, 2-deoxy-D-ribose,1 and D-xylose, which all are aldopentoses.
Is 5 carbon sugar DNA or RNA?
The five-carbon sugar in DNA is called deoxyribose, while in RNA, the sugar is ribose.
What are pentose sugars?
In chemistry, a pentose is a monosaccharide (simple sugar) with five carbon atoms. The chemical formula of all pentoses is C. 5H. 10O. 5.
What are hexose sugars?
hexose. [ hĕk′sōs′ ] Any of various simple sugars (monosaccharides), such as glucose and fructose, that have six carbon atoms per molecule.
What attaches to the 5 carbon sugar?
phosphate group
The phosphate group attached to the 5′ carbon of the sugar on one nucleotide forms an ester bond with the free hydroxyl on the 3′ carbon of the next nucleotide.

What is pentose sugar?
What is aldose and hexose?
In particular, a hexose is a monosaccharide with six carbon atoms. Monosaccharides may also be classified based on the type of carbonyl group they contain. An aldose is a monosaccharide that contains an aldehyde group (-CHO) at position 1 whereas a ketose is one that contains a ketone (C=O) at position 2.
What is attached to the 5 carbon of deoxyribose in DNA?
The 5′ carbon of one deoxyribose is linked to the 3′ carbon of another deoxyribose by a phosphate group. Each strand ends with part of the sugar ring exposed based on these connections.
Which of the following is a monosaccharide with 5 carbon atoms?
Xylose is a monosaccharide and non-nutritive sweetener. It is composed of 5 carbon atoms.
Which of the following is a monosaccharide with five carbon atoms *?
The monosaccharides can be divided into groups based on the number of carbon atoms in the molecules, thus: trioses have 3-C atoms, tetroses have 4-C atoms, pentoses have 5-C atoms, and hexoses have 6-C atoms. Within each of these groups there are different compounds, each with the same molecular formula.
What are the 3 types of sugars?
Glucose, fructose and galactose are the three monosaccharides important in nutrition.
