Which is an accurate description of proteins?
Proteins: Large molecules composed of one or more chains of amino acids in a specific order determined by the base sequence of nucleotides in the DNA coding for the protein. Proteins are required for the structure, function, and regulation of the body’s cells, tissues, and organs.
What is the description of protein?
Proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body’s tissues and organs. These proteins provide structure and support for cells. On a larger scale, they also allow the body to move.
Which of the following statements about the structure of proteins is true?
Answer (e) Proteins are heteropolymers containing strings of amino acids.
Which of the following statements is true about the primary 1 structure of protein?
Correct answer: The primary structure of a protein involves the amino acid sequence in the polypeptide chain. The amino acids in this chain are held together by peptide bonds.
Which is the correct description of proteins?
Proteins are macromolecular polypeptidesi.e., very large molecules (macromolecules) composed of many peptide-bonded amino acids. Most of the common ones contain more than 100 amino acids linked to each other in a long peptide chain.
What are the characteristics of proteins?
Important functional characteristics of proteins include their glass transition temperature, melting point, isoelectric point, molecular weight, secondary structure, solubility, surface hydrophobicity and emulsification [8]. These characteristics will establish their viability and best use in the food industry.
Which of the following is a protein?
Solution(By Examveda Team) Natural rubber is a protein.
What is protein definition example?
Proteins: Large molecules composed of one or more chains of amino acids in a specific order determined by the base sequence of nucleotides in the DNA coding for the protein. Examples of proteins include whole classes of important molecules, among them enzymes, hormones, and antibodies.
What is the definition of protein in food?
: a nutrient found in food (as meat, milk, eggs, and beans) that is made up of many amino acids joined together, is a necessary part of the diet, and is essential for normal cell structure and function.
Which of the following statement about the structure of protein is true?
Answer (e) Proteins are heteropolymers containing strings of amino acids.
Which of the following is a structure of protein?
The primary structure consists of amino acids that are linked by peptide bonds and form linear chains of polypeptides. Secondary structure is the make up of polypeptide chains that fold up into 3D structures. Tertiary structures are the water soluble proteins that condense into compacted structures.
Which of the following statements are true regarding primary structure of proteins Mcq?
The correct statement is The primary structure of a protein is held together by covalent interactions such as peptide bonds, made during translation. A protein molecule contains amino acid residues and not amino acids because when a peptide bond is formed _________ is lost.
Which of these statements is true about the secondary structure of proteins?
Explanation: Protein helices are always right-handed. The secondary structure occurs in the form of helices and sheets. They are always single stranded and only parts of the protein chain is folded into helices.
Which of the following statements is true about the 1 structure of proteins?
Answer (e) Proteins are heteropolymers containing strings of amino acids.
What is the primary 1 structure of a protein?
The linear sequence of amino acids within a protein is considered the primary structure of the protein. Proteins are built from a set of only twenty amino acids, each of which has a unique side chain. The side chains of amino acids have different chemistries.
Which of the following determine the primary structure of a protein?
The correct statement is The primary structure of a protein is held together by covalent interactions such as peptide bonds, made during translation. A protein molecule contains amino acid residues and not amino acids because when a peptide bond is formed _________ is lost.
What is the correct function of protein?
Proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body’s tissues and organs. These proteins provide structure and support for cells. On a larger scale, they also allow the body to move.
How do you describe the structure of a protein?
Protein has many roles in your body. It helps repair and build your body’s tissues, allows metabolic reactions to take place and coordinates bodily functions. In addition to providing your body with a structural framework, proteins also maintain proper pH and fluid balance.
What are 5 characteristics of proteins?
Important functional characteristics of proteins include their glass transition temperature, melting point, isoelectric point, molecular weight, secondary structure, solubility, surface hydrophobicity and emulsification [8]. These characteristics will establish their viability and best use in the food industry.
What are the characteristics of proteins quizlet?
GENERAL CHARACTERISTICS OF PROTEINS:
- proteins are the most abundant substances in nearly all cells.
- all proteins contain the elements: carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur.
- what are proteins? they are naturally occurring unbranched polymers, in which the monomer units are amino acids.
What characteristics do all proteins have in common?
The common property of all proteins is that they consist of long chains of u03b1-amino (alpha amino) acids. The general structure of u03b1-amino acids is shown in . The u03b1-amino acids are so called because the u03b1-carbon atom in the molecule carries an amino group (u2015NH2); the u03b1-carbon atom also carries a carboxyl group (u2015COOH).
What are the characteristics of protein structure?
The overall structure of the protein includes both alpha helices (green) and beta sheets (red). The primary structure of a protein its amino acid sequence drives the folding and intramolecular bonding of the linear amino acid chain, which ultimately determines the protein’s unique three-dimensional shape.
