Spanish term or phrase: anillo de los atomos de nitrogeno del ciclo de las bases de purina
The full sentence from this text reads as follows:
El formaldehido inactiva los microorganismos por alquilación de los grupos amino y sulfidrilos de las proteínas y anillo de los átomos de nitrógeno del ciclo de las bases de purina.
I can't work out what happens after alkylation of the amino and sulfhydryl groups and would be grateful for any help.

Explanation:
"ciclos" doesn't make any sence in the Spanish, nor in English. It's not needed

Formaldehyde - an overview | ScienceDirect Topics
https://www.sciencedirect.com/

Formaldehyde inactivates microorganisms by alkylating the amino (–NH2) and sulfhydral (–S–H) groups of proteins and ring nitrogen atoms of purine bases. This is shown in Fig. 1.28. The interaction with protein results from a combination with the primary amide as well as with the amino groups. Formaldehyde acts as an alkylating agent by reaction with carboxyl (–C=O), sulfhydryl (-SH), and hydroxyl (-OH) groups. Formaldehyde also reacts extensively with nucleic acid. Two of the four bases in nucleic acids, adenine2 and guanine,3 are purines. In DNA, these bases form hydrogen bonds with their complementary pyrimidines, thymine and cytosine, respectively. This is called complementary base pairing. In RNA, the complement of adenine is uracil instead of thymine.

ring of nitrogen atoms in the purine bases cycle


Explanation:
From the sciencedirect website below: 'Basic purine has nine atoms in its structure. Purine has two cycles: a six-membered pyrimidine ring and a five-membered imidazole ring fused together. Four nitrogen atoms are present at the 1, 3, 7, and 9 positions. The numbering of purine starts with the first nitrogen of the six-membered ring and then proceeds in an anticlockwise direction. The imidazole ring is numbered clockwise.'

Asker: Thank you for your response and helpful examples. I gave the points to Neil because of his explanation about how "ciclos" could be left out but thanks very much anyway!
