10 Questions
Define an amino acid and explain its role in protein structure.
An amino acid is a repeating monomer of a protein, containing an amino group and a carboxylic acid group. Amino acids in a protein are held by peptide bonds, and human proteins are made of L-α-amino acids, with only 20 standard amino acids.
What is the general structure of an α-amino acid and what are the components of this structure?
The general structure of an α-amino acid consists of an amino group (NH2), a carboxylic acid group (COOH), and a side chain group (R) attached to the central carbon (Cα).
How are amino acids classified based on their characteristics? Provide at least two classification criteria.
Amino acids are classified based on their chemical nature, nutritional essentiality, and metabolic products/fate.
Explain the classification of proteins based on their function and chemical nature.
Proteins are classified based on their function and chemical nature (composition). They can also be classified based on their shape.
What are standard amino acids, and how many of them are there?
Standard amino acids are the amino acids found in proteins, genetically coded, and totaling 20.
What are the learning objectives related to the classification of amino acids discussed by Dr. Chandrika D Nayak?
The learning objectives related to the classification of amino acids discussed by Dr. Chandrika D Nayak include the classification based on chemical nature, nutritional essentiality, metabolic products/fate.
How is the general structure of an alpha-amino acid defined?
The general structure of an alpha-amino acid is defined by the presence of an amino group (NH2), a carboxylic acid group (COOH), and a side chain group (R) attached to the central carbon (Cα).
What is the definition of an amino acid according to Dr. Chandrika D Nayak?
According to Dr. Chandrika D Nayak, an amino acid is the repeating monomer of a protein, containing an amino group and a carboxylic acid group. Amino acids in a protein are held by peptide bond, and human proteins are made of L-α-amino acids, with only 20 being called standard amino acids.
How are Glycine and Alanine structured?
Glycine is structured with an amino group (NH2), a carboxylic acid group (COOH), and a hydrogen (H) as the side chain group. Alanine is structured with an amino group (NH2), a carboxylic acid group (COOH), and a methyl (CH3) group as the side chain group.
What are standard amino acids and how many are there?
Standard amino acids are the amino acids found in proteins, genetically coded, and totaling 20 in number.
