Definition

noun

(1) An aldopentose (which means a five carbon sugar with an aldehyde functional group in its linear form) with a chemical formula C5H10O5

(2) A sugar monomer in RNA (Ribonucleic acid); also found in other metabolically important compounds, e.g. ribonucleotides, nucleic acids, riboflavin, etc.


Supplement

Its close relative is deoxyribose, which is a constituent of dna (deoxyribonucleic acid). The difference between them is that ribose has one more oxygen atom in its molecule than deoxyribose.

Re: why nucleus is said to be acid

... bases, which are obviously basic. But why are they acidic? I think the reason is in the phosphate groups. The ATGCs are basic, the (deoxy)ribose are sugers, hence neutral. But the phosphate groups are acidic. This is why when you store DNA, you store them as their salt form, which can ...

Re: What is a monomer?

... can be applied to both monomer and polymer—nobody says chemists are easy to get along with—individual sugars like glucose or galactose or ribose etc. are the monomers while pectin or starch or O- or N-linked glycopeptide carbohydrate moieties are polymers. Lipids are a bit more problematic ...

Re: Origin of Life

... Cyanide formed. As the compounds were heated further they reacted to form even more complex chemical molecules such as acetaldehyde, glycine, and ribose (a sugar). Inestingly, as you may know, some of these molecules are essential to life and are found in our bodies. Eventually, these chemicals ...
