What elements most often compose protein?

Answer 1

Proteins are the most abundant intracellular macro-molecules. They are connected intimately with all chemical and physical activity, which makes up the life of the cell. Proteins are present in and vital to all living cells. They provide structure and protection in the form of skin, hair, callus, cartilage, ligaments, muscles, tendons. They also regulate and catalyze the body chemistry in the form of hormones, enzymes, and immunoglobulins.

Answer 2

Some important characteristics of protein are:

• Amino acids are connected by peptide bonds
• Linear polymers built of amino acids Sequence determines protein function
• All proteins from bacteria to humans aremade of the same set of 20 amino acids
• Can be rigid or flexible (function)
• Linear polymers built of amino acids

Answer 3

Proteins are made of various amino acids; amino acids are characterized by an amine group and a carboxylic acid group along with a side chain that changes depending on the amino acid, amine groups are characterized by the specific way a nitrogen molecule is put together with hydrogen, and the same can be said about carboxylic acid with carbon and oxygen. So proteins are not necessarily characterized by a single element but the way the elements are put together. although it is understood that nitrogen makes up about 16% of protein structures if you wanted a single element that is used a lot in protein.

Answer 4

Nitrogen.

To name a few, nitrogen is not in lipids, nucleotides, and carbohydrates; which makes it the characteristic element in a protein

Answer 5

Proteins are important molecules in cells. Proteins are the major component of the dry weight of cells.
