1. Proteins
   Complex nitrogenous organic compounds of high molecular weight made of amino acids; essential for growth and repair of animal tissue. Many, but not all, proteins are enzymes.

2. proteins
   (Humans as organisms) organic compounds made up of amino acid molecules. One of the three main food groups, proteins are needed by the body for cell growth and repair.

3. Proteins
   usually very large molecules, from 10,000 to 200,000 amino acids, which form the structural component of a cell'smatrix. and cytoskeleton. All enzymes are proteins.

5. Proteins
   Proteins are substances that are essential parts of the body. For example, they form the structural material of muscles, tissues and organs. In addition, enzymes are proteins, as are many hormones. Proteins are required in the diet (from foods such as meat and dairy products) so that they can be bro...

6. Proteins
   The chemical building blocks from which mammalian cells, organs, and tissues like muscle are made. Proteins also serve double-duty as hormones, enzymes and antibodies, which help fight off invading germs. Proteins are made of long chains of even smaller building blocks called amino acids. Amino acid...

9. Proteins
   Proteins: Large molecules 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 u...

10. proteins
    Nitrogenous organic compounds, containing more than about 100 amino acid residues, molecular weight 8,000-200,000, in vegetable and animal matter. Proteins yield amino acids on hydrolysis and are foods assimilated as amino acids and reconstructed in the protoplasm. ... (12 Dec 1998) ...
