BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Organic bases are usually, but not always, proton acceptors. They usually contain nitrogen atoms, which can easily be protonated . For example, amines or nitrogen-containing heterocyclic compounds have a lone pair of electrons on the nitrogen atom and can thus act as proton acceptors.

Detailed explanation-2: -Nitrogenous bases are organic molecules that contain a ring structure that includes both carbon and nitrogen atoms and can act as a base in chemical reactions. The lone pair of electrons on one of the nitrogen atoms acts as a Lewis base, able to donate a pair of electrons in a chemical reaction.

Detailed explanation-3: -Organic molecules are molecules that are made of carbon and hydrogen, and can include other elements. Organic molecules must contain carbon atoms covalently bonded to hydrogen atoms (C-H bonds). They usually involve oxygen and can also contain nitrogen, sulfur, phosphorous, and others.

Detailed explanation-4: -Functional groups containing oxygen atoms: carbonyl group C=O, alcohol R-OH, and ether R-O-R. The lone pair electrons on O in these groups are able to accept the protons, so functional groups like aldehyde, ketone, alcohol and ether are all organic bases.

Detailed explanation-5: -A nitrogenous base is a nitrogen-containing organic molecule having similar physical properties as a base.
