What is the basic definition of protein?
A protein is a naturally occurring, extremely complex substance that consists of amino acid residues joined by peptide bonds. Proteins are present in all living organisms and include many essential biological compounds such as enzymes, hormones, and antibodies.
What is simple protein with example?
(a) Simple proteins. On hydrolysis they yield only the amino acids and occasional small carbohydrate compounds. Examples are: albumins, globulins, glutelins, albuminoids, histones and protamines.
What are conjugated proteins How is peptide linkage form in protein?
Peptide bonds form through a process known as dehydration synthesis. In dehydration synthesis, a chemical bond is formed through the loss of a water molecule. When two amino acids bond, the nitrogen of one amine group will bond to the carbon of the other amino acids carboxyl group.
What is protein and its classification?
Proteins are macromolecular polypeptides, that is, very large molecules (macromolecules) made up of several amino acids bound to the peptides. Most common ones contain more than 100 amino acids that are linked together in a long chain of peptides.
What is the use of simple protein?
What are proteins and what do they do?
| Function | Description | Example |
|---|---|---|
| Structural component | These proteins provide structure and support for cells. On a larger scale, they also allow the body to move. | Actin |
| Transport/storage | These proteins bind and carry atoms and small molecules within cells and throughout the body. | Ferritin |
Is nucleoprotein a simple protein?
nucleoprotein, conjugated protein consisting of a protein linked to a nucleic acid, either DNA (deoxyribonucleic acid) or RNA (ribonucleic acid). The protein combined with DNA is commonly either histone or protamine; the resulting nucleoproteins are found in chromosomes.
What is called peptide linkage?
(i) A peptide linkage is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H2O). This is a dehydration synthesis reaction (also known as a condensation reaction), and usually occurs between amino acids.
What is peptide linkage in proteins?
A peptide bond is basically an amide-type of covalent chemical bond. This bond links two consecutive alpha-amino acids from C1 (carbon number one) of one alpha-amino acid and N2 (nitrogen number two) of another. This linkage is found along a peptide or protein chain.
What are types of proteins?
There are seven types of proteins: antibodies, contractile proteins, enzymes, hormonal proteins, structural proteins, storage proteins, and transport proteins.
What are the 3 classifications of protein?
They are classified into three types; fibrous, globular and derived protein.
- Fibrous protein: They are elongated or fiber like protein.
- Globular protein: They are spherical or globular in shape.
- Derived protein:
