Amino Acids and Proteins Quiz

Amino Acids and Proteins: Key Concepts

• Amino acids are the building blocks of proteins, and there are 20 different types of amino acids commonly found in proteins.
• Amino acids have a similar structure, consisting of a central carbon atom attached to an amino group, a carboxyl group, a hydrogen atom, and a variable group (R).
• Amino acids can be classified based on the chemical nature of their R group, such as polar, non-polar, or charged.
• The acid-base properties of amino acids depend on the amino and carboxyl groups attached to the α-carbon, the functional groups represented by R, and the pH of the medium.
• Amino acids can exist in different isomers, but cells synthesize L-isomers of amino acids due to the stereospecificity of enzymes.
• Proteins are polypeptides composed of 20 different amino acids in a sequence encoded by the gene, and the folding of proteins depends on the chemical and physical properties of the amino acids.
• The isoelectric point (pI) is the pH at which an amino acid or protein is electrically neutral, and it depends on the charges of the amino acid side chains.
• Peptide bonds join amino acids in proteins, and they have a direction from the amino terminal residue to carboxyl terminal residue.
• There is no rotation about peptide bonds due to their double bond characteristics, and the carbonyl oxygen and amide hydrogen are in the trans orientation.
• Cysteine is involved in disulfide bond formation, which plays a crucial role in protein folding and stability.
• The folding of proteins into a complex and specific three-dimensional structure is determined by the sequence of amino acids.
• Peptides are named from the N-terminal end to the C-terminal end, and acidic proteins have many negatively charged amino acids and a low pI, while basic proteins have many positively charged amino acids and a high pI.
