Answer:  They possess different functional groups.

Explanation:

Organic compounds are molecules composed of many carbon atoms bound together and in turn bound to hydrogen atoms. These molecules form the lipids, proteins, carbohydrates and nucleic acids that constitute all living beings. The reason why there is so much variety of organic molecules is because each one can have one or several <u>functional groups in different positions, which gives them unique properties.</u>

So a functional group is a group of atoms linked in a certain way, which present a specific physical-chemical structure and properties that characterise the organic compounds that contain them.

Examples are:

  • Lipids: A carboxylic acid
  • Proteins: A carboxyl group and an amino group
  • Carbohydrates: An aldehyde or ketone group
  • Nucleic acids, Nucleotides: A phosphate group

A three banded isoenzyme pattern with a 1:2:1 intensity ratio indicates a ________________ protein.
djverab [1.8K]

A three banded isoenzyme pattern with a 1:2:1 intensity ratio indicates a <u>dimeric</u> protein.

  • Isozyme is a multimeric forms of enzyme having similar specificity of the substrate but differences in kinetics and molecular weights of the enzymes.
  • The banding patterns of isozyme observed from electrophoresis is related to the genetic conditions in which different combination of polypeptide chains exhibited under the mendelian principles.
  • Hence with the intensity of 1:2:1 ratio, three banded phenotypes are formed having two homomeric and one heteromeric form from the dimeric protein in both multiple alleles at single loci and multiple /single allele at multiple loci.
