Purines have a fused-ring structure that is more susceptible to hydrolysis due to the presence of two nitrogens in the ring. These nitrogens have lone pairs that can facilitate the cleavage of glycosidic bonds during hydrolysis. Pyrimidines, on the other hand, have a single nitrogen in the ring and a more stable structure that is less prone to hydrolysis.
What else can I help you with?
Why are adenine and guanine longer than thymine and cytosine?
Adenine and guanine are longer because they have double rings in their chemical structure, known as purines, which contain more atoms than the single-ring structures of thymine and cytosine, known as pyrimidines. This additional ring in purines makes them physically larger molecules compared to pyrimidines.
Where did the chemistry take place?
There is a phrase coined by some scientific conference that states something along the lines of... life is the expression of purines and pyrimidines. I suppose that means at the formation of nucleic acids, as far as we know. Most likely ribonucleic acids, to be more specific.
What is Thymine and cytosine also called?
Thymine and cytosine are two nitrogen bases found in DNA. DNA is composed of thousands of nucleotides which are composed of one of four nitrogen bases. Both of these nitrogen bases are also pyrimidines, or they have one ring like structure See related link for more info on thymine, cytosine and pyrimidines.
Does the double ring in purines hold it together?
Yes, the double ring structure in purines (adenine and guanine) provides structural stability and rigidity to the molecule. This double-ring structure is essential for the function of purines in nucleic acids where they are involved in base pairing and DNA/RNA stability.
Why do some flowers have anthers hanging out?
The advantage is anthers can pollinate by wind more easily.
Do purines help gout?
That depend on what you mean by the question. Purines are what is required to to make uric acid in the body, so the more purines there are in the system the more uric acid is formed, If one has a predisposition to gout then more purines you eat or need to metabolize in other ways the greater the risk of a gout attack.
Why are adenine and guanine longer than thymine and cytosine?
Adenine and guanine are longer because they have double rings in their chemical structure, known as purines, which contain more atoms than the single-ring structures of thymine and cytosine, known as pyrimidines. This additional ring in purines makes them physically larger molecules compared to pyrimidines.
Is prune juice high in purines?
Prune juice is not considered high in purines. Purines are compounds found in certain foods that can contribute to increased uric acid levels in the body, which may lead to gout. Prunes and prune juice are generally low in purines and can be a healthy option for most diets. They are more recognized for their fiber content and benefits for digestive health.

Why RNA can be hydrolyzed by dilute alkali but not DNA?
RNA contains a hydroxyl group on the 2' carbon of its ribose sugar, making it more prone to hydrolysis in alkali conditions. In contrast, DNA lacks this hydroxyl group due to a deoxyribose sugar, making it more stable and resistant to hydrolysis in alkaline conditions.
Does soya beans have uric acid?
String beans contain purines and these are what the body metabolises into uric acid. All thing s made of living cells with a nucleus have some purines. some have more then others.String beans contain relatively low amounts of purines Beans, French(string beans, haricot) 37 mg Total Purines in uric acid/100 g (Average)
Increase in uric acids indicates what?
It can mean a weakness in the kidney, however it can also mean that there has been a change in diet to foods that have more purines in them.

Is there such thing as 'more easily'?
Yes, it is correct to say that something is done more easily. Easily is an adverb.
