Question

Heterocyclic ring is not found in
(A) Adenine
(B) Guanine
(C) Uracil
(D) Valine​

Answer 1

Answer:

While atoms that are neither carbon nor hydrogen are normally referred to in organic chemistry as heteroatoms, this is usually in comparison to the all-carbon backbone. But this does not prevent a compound such as borazine (which has no carbon atoms) from being labelled "heterocyclic".

Answer 2

Answer:

Heterocyclic ring is not found in Valine​.

Explanation:

• Alpha- amino carboxylic acids, such as valine (C5H11NO2), have this chemical formula. A carboxylic acid moiety (-COOH), an amino group (-NH2), a hydrogen atom (-H), and an isopropyl (-CH(CH3)2) side chain are all joined to the core alpha carbon atom.
• a substance that is utilized to create one of the components of DNA and RNA. It also makes up a variety of compounds in the body that provide cells energy. A subclass of purine is adenine.
• Adenine, cytosine, thymine, and guanine are the other three major nucleobases that can be found in the nucleic acids DNA and RNA.
• One of the four nucleobases found in RNA, whose names are represented by the letters A, G, C, and U, is uracil.

Hence, option (D) is correct.
