Biochemistry Functional Groups Quiz

The given functional group is acetyl which is commonly represented as -COCH3, and it consists of a carbonyl group attached to a methyl group.

The correct name for the functional group in question is 'Amido', which consists of a carbonyl group attached to an amine group. The incorrect answers are: Hydroxyl, which consists of an -OH group; Carboxyl, which consists of -COOH group; and Amino, which consists of -NH2 group.

The correct answer is 'Amino (protonated)' because it refers to an amine functional group that has gained a proton.

An anhydride functional group consists of two acyl groups bonded to an oxygen atom. It is different from ketones, esters, and alcohols in its structure and properties.

The correct answer is Aldehyde (Carbonyl) because aldehydes are compounds containing a carbonyl group bonded to a hydrogen atom. The other options provided are different functional groups commonly found in organic chemistry.

The correct answer is Ketone (Carbonyl) because a ketone is a compound in which a carbon atom is connected to an oxygen atom by a double bond. This functional group is called a carbonyl group. An alcohol has a hydroxyl group (-OH), an ester has a carbonyl group connected to an oxygen atom, and an amine has an amino group (-NH2).

The functional group depicted is a carboxylate group, which consists of a carbonyl group attached to a hydroxyl group and is commonly found in organic acids.

A disulfide bond refers to a covalent bond between two sulfur atoms. In contrast, a hydroxyl group consists of an oxygen and hydrogen atom, a carbonyl group has a carbon double-bonded to an oxygen atom, and an amino group includes a nitrogen atom bonded to hydrogen atoms.

The correct answer is Enol which is a compound containing a hydroxyl group bonded to a carbon-carbon double bond. An ester is a functional group containing a carbonyl and an alkoxy group, a ketone is a carbonyl group bonded to two carbon atoms, and an alkene is a double bond between two carbon atoms.

The correct answer is 'Ester' as it is a functional group characterized by a carbon atom double bonded to an oxygen atom, which is also bonded to an R group and another oxygen atom.

Ethers are organic compounds in which an oxygen atom is bonded to two alkyl or aryl groups. Aldehydes, amines, and ketones are different functional groups with distinct chemical structures and properties.

The correct functional group in this case is Ethyl, which consists of two carbon atoms in a chain connected by a single bond.

The correct answer is Guadidinium, a functional group with a positively charged nitrogen atom in chemical structure. Hydroxyl, Carboxyl, and Amine are other common functional groups but they are not Guadidinium.

The correct functional group for this question is Hydroxyl, which is characterized by an oxygen atom bonded to a hydrogen atom. Carbonyl consists of a carbon atom double bonded to an oxygen atom. Amino contains a nitrogen atom bonded to two hydrogen atoms. Ester consists of a carbonyl group bonded to an alkyl group.

Imidazole is a five-membered aromatic heterocyclic ring. It can act as a functional group in organic chemistry. The incorrect answers do not represent the structure or properties of an imidazole functional group.

An imine is a functional group that contains a carbon-nitrogen double bond. Alcohols contain a hydroxyl (-OH) functional group, aldehydes contain a carbonyl group bonded to a hydrogen atom, and esters contain a carbonyl group bonded to an oxygen atom.

The correct answer is 'Methyl' because it is a functional group consisting of a carbon atom bonded to three hydrogen atoms. Hydroxyl, Carbonyl, and Amino are different functional groups with distinct structures and properties.

A mixed anhydride is a functional group composed of an acyl group bonded to an alkyl or aryl group.

The given functional group is known as N-Substituded Amine (Schiff Base). An aldehyde, phenol, and carboxylic acid are different functional groups with distinct chemical properties and structures.

The functional group shown is a phenyl group, which consists of a benzene ring attached to another molecule. Methyl, hydroxyl, and carbonyl are other common functional groups with distinct structures and properties.

The correct answer, Phosphoanhydride, refers to a functional group composed of two phosphate groups linked by a high-energy anhydride bond. Carbonyl, Hydroxyl, and Amine are also common functional groups in organic chemistry but do not describe the specific functional group shown in the question.

The correct answer is 'Phosphoryl', which is a functional group consisting of a phosphate group attached to another molecule. This functional group is commonly found in various biological molecules such as nucleic acids and phospholipids.

The correct answer is Sulfhydryl, which consists of a sulfur atom bonded to a hydrogen atom. Carbonyl, Amino, and Hydroxyl are also functional groups but differ in their chemical composition and properties.

A thioester is a functional group in organic chemistry that is similar to an ester, but with a sulfur atom in place of the oxygen atom. It is important to distinguish thioesters from esters which have an oxygen atom instead. Sulfides and Aldehydes are different functional groups and not to be confused with thioesters.
