Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Proteins are compounds formed in the cells of plants and animals. Which element is included in every protein molecule?
A
calcium
B
carbon
C
fluorine
D
sodium
Explanation: 

Detailed explanation-1: -Proteins are made of carbon, hydrogen, oxygen, and nitrogen (CHON ). Nucleic acids such as DNA and RNA contain carbon, hydrogen, oxygen, nitrogen, and phosphorus (CHON P). Name the 4 main elements that make up 95% of an organism.

Detailed explanation-2: -Proteins contain the elements carbon, hydrogen, and oxygen just as carbohydrates and lipids do, but proteins are the only macronutrient that contains nitrogen. In each amino acid the elements are arranged into a specific conformation around a carbon center.

Detailed explanation-3: -Proteins, carbohydrates and lipids are made from three basic molecules: carbon, hydrogen and oxygen. However, all proteins contain an element not found in carbohydrates and lipids is nitrogen. Nitrogen which is present in all amino acids (the building blocks that make up the protein chains).

Detailed explanation-4: -Nitrogen: Proteins are essential bio-molecules that actively participate in many important and fundamental aspects of life. Nitrogen is the element used for protein synthesis and is an essential constituent of amino acids.

Detailed explanation-5: -Proteins are complex, organic compounds composed of many amino acids linked together through peptide bonds and cross-linked between chains by sulfhydryl bonds, hydrogen bonds and van der Waals forces.
