protein

A linear polymer of amino acids joined by peptide bonds in a specific sequence.

Protein

long heteropolymers of amino acid residues linked by peptide bonds formed by the condensation of a-amino and a-carboxyl groups

Protein

A molecule comprised of long chains of amino acid molecules. Proteins, which include enzymes, are polypeptides.

protein

(Learning Modules / Biology / DNA / Glossary) Long-chained molecules used to build and repair cells, made of one or more chains of amino acids

Protein

The term applied to the group of substances found within the body, e.g. coagulation factors, proteins, immunoglobulins and albumin.

Protein

High molecular weight compounds containing nitrogen, carbon, hydrogen, oxygen and usually sulphur (amino acids). It is an essential part of the protoplasm of all living cells. Proteins may be structural or an enzyme.

protein

Composed of amino acids, proteins are a key component in many cell structures. In addition, many hormones and enzymes that regulate cells are proteins.

Protein

a class of biochemicals made from amino acids in specific sequences. Proteins can be very large molecules with very specific shapes in folds and sheets, etc. They have three prominent functions in the body. Some varieties are, save for bone, the structural components of cells and so of the body. Other varieties are enzymes, which coordinate the che...

Protein

Large molecules composed of long chains of amino acids (see also amino acids). Essential for growth and repair, but also a source of energy with one gram of protein supplying four Calories when oxidised. Excess protein (amino acids) cannot be stored as such, therefore daily intake required.

Protein

Protein: A large molecule 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. Each protein has unique functions. Proteins are essential components...
