What is the general structure of protein?

Answer 1

Proteins are made up of amino acids that are bonded together by peptide bonds. The amino acids become part of a "string" termed a polypeptide chain.

Ribosomes are the organelles responsible for assembling proteins. They get instructions from RNA that tell them which amino acid to code for while assembling a protein.

Answer 2

Proteins are polymers composed of amino acids linked together by peptide bonds. They have a primary structure (sequence of amino acids), secondary structure (alpha helices and beta sheets), tertiary structure (overall 3D shape), and sometimes a quaternary structure (multiple protein subunits associated together).

Answer 3

There are four level types of protein structure. The primary structure refers to amino acid, secondary structure refers to highly local sub-structures, tertiary structure for the shape of the entire protein, and quaternary structure for protein that are built of sub-units for another level of structure.

Answer 4

The primary structure is the order of the amino acids in a chain. The secondary structure is the formation of hydrogen bonds to form the amino acid chain into alpha helices or beta sheets. The tertiary structure is bonding between R-groups of the amino acids to bend the helix or sheet into a 3-D shape. (Note - this may be as far as some proteins go, other go on to quaternary structure) The quaternary structure is when more than one tertairy structue join - the hemoglobim molecule that carries oxygen in our blood is a quaternary structure that's made up of 4 tertiary structures.

Answer 5

There are four levels that determine making a protein's specific confirmation.

1-Primary Structure: The specific amino acid sequence determined by gene with your DNA.

2-Secondary Structure: Coils and folds produced when the polypeptide backbone of adjacent amino acid interaction.

3-Tertiary Structure: As second structure is formed Hydrogen bonds form between side chains of side by side secondary structure.

4-Quaternary Structure: This level of protein structure does not exist in all proteins. It only exist in proteins that are formed from two or more interwoven polypeptides on their own they are dysfunctional, but together they are functional.

Answer 6

Proteins are macromolecules (heteropolymers) made up from 20 different L-a-amino acids, also referred to as residues. Below about 40 residues the term peptide is frequently used. A certain number of residues is necessary to perform a particular biochemical function, and around 40-50 residues appears to be the lower limit for a functional domain size. Protein sizes range from this lower limit to several hundred residues in multi-functional proteins. Very large aggregates can be formed from protein subunits, for example many thousand actin molecules assemble into a an actin filament. Large protein complexes with RNA are found in the ribosome particles, which are in fact 'ribozymes'

Answer 7

Proteins are an important class of biological macromolecules present in all organisms. All proteins are polymers of amino acids. Classified by their physical size, proteins are nanoparticles (definition: 1-100 nm). Each protein polymer - also known as a polypeptide - consists of a sequence of 20 different L-α-amino acids, also referred to as residues. For chains under 40 residues the term peptide is frequently used instead of protein. To be able to perform their biological function, proteins fold into one or more specific spatial conformations, driven by a number of non-covalent interactions such as hydrogen bonding, ionic interactions,Van Der Waals forces, and hydrophobic packing. To understand the functions of proteins at a molecular level, it is often necessary to determine their three-dimensional structure. This is the topic of the scientific field of structural Biology, which employs techniques such as X-ray crystallography, NMR spectroscopy, and dual polarisation interferometry to determine the structure of proteins.

Protein structures range in size from tens to several thousand residues [1] Very large aggregates can be formed from protein subunits: for example, many thousand actin molecules assemble into a microfilament.

A protein may undergo reversible structural changes in performing its biological function. The alternative structures of the same protein are referred to as different conformations, and transitions between them are called conformational changes.

Answer 8

A protein structure is determined by the number and sequence of amino acids that form a protein. There are four protein structure levels.

Answer 9

-C-C-N-C-C-N-C-C-N ... the fun begins when one of the -C's- can accept a side branch.

The peptide bond is here.

Answer 10

Examples of the structure of proteins are your hair and your muscles. Their basic linear structure is a [usually] long string of Amino Acids.
