In organic chemistry, a tetrose is a monosaccharide with 4 carbon atoms. They have either an aldehyde ( −CH=O ) functional group in position 1 ( aldotetroses ) or a ketone ( >C=O ) group in position 2 ( ketotetroses ).

Classify monosaccharides as aldoses or ketoses and as trioses, tetroses, pentoses, or hexoses. Distinguish between a D sugar and an L sugar. The naturally occurring monosaccharides contain three to seven carbon atoms per molecule.

2021年3月1日 · Monosaccharides are the simplest form of carbohydrates. They are classified according to the number of carbon atoms in a monosaccharide. In particular, a tetrose is a monosaccharide with four carbon atom s. Monosaccharides may also be classified based on the type of carbonyl group they contain.

Monosaccharides can be classified by the number of carbon atoms they contain: diose (2), triose (3), tetrose (4), pentose (5), hexose (6), heptose (7), and so on. They can also be classified based on whether or not they contain an aldehyde (aldose) or ketone (ketose).

The meaning of TETROSE is any of a class of monosaccharides C4H8O4 (as erythrose) containing four carbon atoms.

2025年3月19日 · Monosaccharides of specific sizes may be indicated by names composed of a stem denoting the number of carbon atoms and the suffix -ose. For example, the terms triose, tetrose, pentose, and hexose signify monosaccharides with, respectively, three, four, …
