What is the four levels of proteins?
Proteins have primary structure, which is their amino acid sequence, secondary structure, which is either the alpha helix or the beta pleated sheet, tertiary structure, the protein's geometric shape, and quaternary structure, the arrangement of multiple protein subunits.
What is the primary structure of DNA?
The sequence of nitrogenous bases forms the primary structure of the molecule, analagous to the sequence of amino acids in a polypeptide.
Hemoglobin represents which level of protein organization?
Haemoglobin has a protein structure upto quarternary structure since it is a dimer made up of two monomeric units, each of which are two in number. Thus the overall structure has 4 monomeric units.
How is protein made in a cell?
Primary structure: Protein synthesis makes polypeptide chain with the process of translation and transcription. Amino acid sequences are attached by peptide bonds.Secondary structure: Hydrogen bonds attract one amino acids to one another, resulting in a twisting and folding of neighboring amino acids. These are all attached by hydrogen bonds. It may form an alpha helix, which is a twisted form, and/or Beta pleated sheet which is the folded form.Tertiary structure: Three dimensional shape begin to form from the polypeptide chain. This is perhaps the most important structure. It may allow amino acids at opposite ends to be close to each other to allow binding of specific substrate. Covalent bonds from disulfide bridges, as well as hydrogen bonds, ionic bonds, and hydrophobic interactions are all present. Many proteins are functional at this point. Some, like hemoglobin, needs further configuration to become a functional protein.Quaternary structure: In the quaternary structure, two or more polypeptide chains in the tertiary structure binds to each other, which forms a functional protein.
Is alanine a type of polymer that forms a polypeptide?
No, alanine, which is an amino acid, is a type of monomerthat can form a polypeptide. The individual units are monomers, the long chain is a polymer.

What are the four basic levels of organization of a protein?
Levels of Protein structure: 1. Primary: refers to the unique sequence of amino acids in the protein. All proteins have a special sequence of amino acids, this sequence is derived from the cell's DNA. 2. Secondary : the coiling or bending of the polypeptide into sheets is referred to the proteins secondary structure. alpha helix or a beta pleated sheet are the basic forms of this level. They can exist separately or jointly in a protein. 3. Tertiary: The folding back of a molecule upon itself and held together by disulfide bridges and hydrogen bonds. This adds to the proteins stability. 4. Quaternary: Complex structure formed by the interaction of 2 or more polypeptide chains.

What are the four structure levels of a protein?
The four levels of protein are: 1) Primary Structure 2) Secondary Structure 3) Tertiary Structure 4) Quaternary Structure The primary structure is just the amino acids bonded to each other in a linear fashion. Secondary structure is where the alpha-helices, beta-sheets, and b-turns come into play. The tertiary structure is when a single amino acid chain forms a 3D structure. And lastly, the quaternary stuture is when 2 or more tertiary structures complex.
Which amino acid contains sulfur atoms that form covalent disulfide bonds in its tertiary structure?
Cysteine forms disulfide bonds
What forms together to make a polypeptide?
amino acids
When you join two glucose molecules you get maltose what is the molecular structure of maltose?
The actual diagrams of the molecules in helix and pleated forms can be found on Wikipedia by searching Maltose. This site would not let me import the pics. sorry
