Originally prescribed in the late 1950s as a morning sickness pill, scientists soon realized that the drug thalidomide was causing babies to be born with a condition called phocomelia, involving the malformation of limbs during fetal development. Within 5 years of its introduction, the drug was pulled from the market because of the evidence that it was a(n) .

the drug was pulled from the market because of the evidence that it was a(n) teratogen

Explanation:

Teratogens are drug or other agents that cause physical or functional bnormalities in fetuses that are exposed to such agents. A typical example is alcohol. The degree of the abnormality on the fetus depends on a number of factors which are:

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure
