What additional elements are in proteins?

In addition to carbon, hydrogen, and oxygen atoms, all proteins contain nitrogen and sulfur atoms, and many also contain phosphorus atoms and traces of other elements.

What are proteins secondary structure made from?

The secondary structure arises from the hydrogen bonds formed between atoms of the polypeptide backbone. The hydrogen bonds form between the partially negative oxygen atom and the partially positive nitrogen atom.

What two molecules make up proteins?

All proteins are made up of different arrangements of the same 20 kinds of amino acids. Amino acids are the monomers that make up proteins. Each amino acid has the same fundamental structure, which consists of a central carbon atom bonded to an amino group (–NH2), a carboxyl group (–COOH), and a hydrogen atom.

What are the polymer of proteins?

amino acids
Proteins – polymers are known as polypeptides; monomers are amino acids.

How is protein made?

To build proteins, cells use a complex assembly of molecules called a ribosome. The ribosome assembles amino acids into the proper order and links them together via peptide bonds. This process, known as translation, creates a long string of amino acids called a polypeptide chain.

How is the secondary protein structure formed from the primary structure?

A protein’s primary structure is defined solely by its amino acid sequence, and is constructred by peptide bonds between adjacent amino acid residues. Secondary structure results from hydrogen bonding along the polypeptide backbone, resulting in alpha-helices and beta-pleated sheets.

What is two or more elements chemically combined?

Elements can be chemically combined into compounds, therefore, a compound consists of two or more elements combined, in definite proportions, by chemical means. Compounds may be formed by combining atoms of their constituent elements by ionic bonds or by covalent bonds.

Is a protein molecule a polymer?

Proteins are polymers of amino acids. Each amino acid contains a central carbon, a hydrogen, a carboxyl group, an amino group, and a variable R group.

Which contains more molecules a monomer or a polymer?

A monomer is a small molecular sub unit that can be combined with similar sub units to form larger molecules. A polymer is a large molecule made up of chains of repeating basic molecular units called monomers.
