Ribose

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.


Word origin: German, alteration of English arabinuse, a kind of sugar

Chemical formula: C5H10O5

Compare: deoxyribose

Re: Help - Why can't DNA be parallel?

... the 5'-3' strand. I understand this, otherwise there is no way they could base pair. However, they have NOT been flipped UPSIDE DOWN, unlike the riboses/phosphates which have been. The thing I don't understand (ish, now), is why you can't have that ribose/phosphate backbone flipped right side ...

Help - Why can't DNA be parallel?

... regards to DNA's directionality... Why can't it be parallel? I understand the reason why they're anti-parallel is because of the numbering of the ribose sugars. The thing I am confused about is when you look at the two strands, for the one from 3'-5', the base is flipped horizontally (so it can ...

Do the simplest bacteria have ribosomes and helicase?

I don't think ATP is RNA, though it is based on adenine. I don't know the chemistry as well as I should but I think it's adenine + ribose + some phosphorus bonds. I think I understand the basic theory - it's the billions of years and huge numbers part that is giving me heartburn. Nucleotides ...

Both are nucleic acids containing genetic information with different sugars deoxyribose and ribose sugars RNA is more than 'genetic information'. tRNA, microRNA, ribosomes and so on have plethora of other functions. Only mRNA and genome of some viruses falls in ...
