Science. how many carbons can be bonded in chain ( maximum) ? Is the psa isomers reference Prostate Specific Antigen? While it is true that our bodies prefer L-amino acids which are just result of an evolutionary process, does not mean D-amino acids would harm us. Connect and share knowledge within a single location that is structured and easy to search. Geometric isomers are molecules that are locked into their spatial positions with respect to one another because of a double bond or a ring structure. So we go ahead and draw Pyridine is not a hydrocarbon, as hydrocarbons can only contain hydrogen and carbon atoms, by definition. Isomers: "Isomers are two or more compounds that have the same chemical formula but a different arrangement of atoms."
