Document Summary
They usually contain multiple chirality centers, and fischer projections are used to indicate the configuration at each chir ality center. The suffix -ose is used to signify a carbohydrate. Monosaccharides can be classified as either aldose or a ketose i. Aldoses contain an aldehyde moiety, while ketoses contain a ketone moiety e. Aldoses and ketoses can be further classified based on the number of carbon atoms they contain i. This is accomplished by inserting a term (tri, tetra, penta ) immediately before the suffix -ose ii. Glyceraldehyde is one of the smallest compounds considered to be a carbohydrate. It has only 1 chirality center so it can exist as a pair of enantiomers i. c. d. Only + glyceraldehyde (rotates plane-polarized light in a clockwise fashion) is abundant in nature, so glyceraldehyde obtained from natural resources is generally referred to as d-glyceraldehyde. Most naturally occurring carbs can be broken down into d-glyc i. e. f.
