Which one is purines and pyrimidines are bigger?
Purines are larger molecules compared to pyrimidines. Purines consist of a six-membered ring fused to a five-membered ring, while pyrimidines are single-ring structures.
How many rings does a purine have?
A purine has two rings in its structure: a six-membered ring fused to a five-membered ring.
Why is a 5 membered ring better than a 6 membered ring?
It really depends on what you require from it.
How many sides to the ring in gluncose?
Glucose has 6 carbons in its ring structure, so it forms a 6-membered ring. This means glucose has 6 sides in its ring structure.
Does clear eyes contain steroids as ingridients?
No. It contains naphazoline, which is kinda sorta but not very much like a steroid. It has a five membered ring and two six membered rings it it (steroids have three six membered rings and one five membered rings). However, the five membered ring in naphazoline contains nitrogen (that in steroids does not) and the six membered rings are aromatic (those in steroids or not). So it's not a steroid, but if you were to glance at a spacefilling model and weren't a chemist I can see how you might mistake it for one.
What is the pyranose and furanose formula for aldohexose?
The pyranose formula for an aldohexose is C6H12O6 and the furanose formula for an aldohexose is also C6H12O6. The difference between them lies in the cyclic structure of the molecule, with pyranose having a six-membered ring and furanose having a five-membered ring.
Structure five membered ring hdrocarbon with 7 carbons?
sedoheptulose-diphosphate
What is beta lactams?
A beta-lactam is a lactam with a four-membered ring structure - a structural element of many antibiotics, including penicillin.
What functional groups are present in nicotine?
Nicotine contains a pyridine ring, which is a nitrogen-containing aromatic ring, and a pyrrolidine ring, which is a five-membered nitrogen heterocycle. These functional groups contribute to the biological activity of nicotine in the central nervous system.
What is a Six-carbon sugar with five-carbon ring?
Ribose is a five-carbon sugar with a five-carbon ring structure found in RNA molecules. Sugars with six carbon atoms, like glucose and fructose, typically form six-membered rings in their structures.
What is an azulene?
An azulene is a bicyclic aromatic hydrocarbon containing a five- and seven-membered fused ring.
What is an azolane?
An azolane is another name for a pyrrolidine, any of a class of heterocyclic amines with a saturated five-membered ring.
