Which of the following contains nitrogen?(A) Fats(B) Proteins(C) Carbohydrates(D) All of the above [1]
Hint: Nitrogen occurs in all organisms, primarily in amino acids, in nucleic acids and in the energy transfer molecule adenosine triphosphate. The human body contains about $3%$ nitrogen by mass, the fourth most abundant element in the body after oxygen, carbon, and hydrogen.
Proteins are large biological molecules or macromolecules consisting of one or more long chains of amino acids and carboxylic acid.. Therefore, proteins are macromolecules formed by amino acids
It also uses proteins to make enzymes, hormones, and other body chemicals. Protein is an important building lock of bones, muscles, skin and blood.
Proteins [2]

Proteins are one of the primary constituents of living matter. They consist of long chains of amino acids, which are bonded together by peptide linkages and thus called polypeptides
Each amino acid contains a carboxylic acid end and an amino end. At a pH of 6-7 (the body’s pH is 7.3) the amino end is protonated, while the carboxylic end remains an anion; this is called a zwitterion
A peptide bond occurs when the carboxylic acid end of one amino acid bonds with. around the peptide bond, as well as the two carbon atoms to which the amino

in life that has all these carbon, hydrogen, nitrogen and oxygen proteins. Okay, the grains are those molecules to contain all of these elements
7: Amino Acids, Proteins, and Enzymes [4]
Proteins may be defined as compounds of high molar mass consisting largely or entirely of chains of amino acids. Their masses range from several thousand to several million daltons (Da)
Proteins serve a variety of roles in living organisms and are often classified by these biological roles. Muscle tissue is largely protein, as are skin and hair
Each type of cell in our bodies makes its own specialized proteins, as well as proteins common to all or most cells. We begin our study of proteins by looking at the properties and reactions of amino acids, which is followed by a discussion of how amino acids link covalently to form peptides and proteins
2.3 Biological Molecules – Concepts of Biology – 1st Canadian Edition [5]
– Describe the ways in which carbon is critical to life. – Explain the impact of slight changes in amino acids on organisms
– Understand the functions of the four major types of molecules. The large molecules necessary for life that are built from smaller organic molecules are called biological macromolecules
Combined, these molecules make up the majority of a cell’s mass. Biological macromolecules are organic, meaning that they contain carbon
Wikipedia [6]
CHON is a mnemonic acronym for the four most common elements in living organisms: carbon, hydrogen, oxygen, and nitrogen.. The acronym CHNOPS, which stands for carbon, hydrogen, nitrogen, oxygen, phosphorus, sulfur, represents the six most important chemical elements whose covalent combinations make up most biological molecules on Earth
|Element||Mass in plants||Mass in animals||Biological uses|. |Carbon||12%||19%||Found in carbohydrates, lipids, nucleic acids, and proteins.|
|Nitrogen||1%||4%||Found in nucleic acids, proteins and some lipids and carbohydrates (E.G sphingolipids, chitin)|. |Oxygen||77%||63%||Found in carbohydrates, lipids, nucleic acids, and proteins.|
Building Blocks of Proteins [7]
Like carbohydrates and lipids, proteins contain the elements carbon (C), hydrogen (H) and oxygen (O), but in addition they also always contain nitrogen (N).. Sulphur is often present as well as iron and phosphorus
The diagram below shows the general structure of an amino acid.. Just like the earlier carbohydrate and lipid molecules ‘R’ represents groups such as –CH3 and –C2H5
The diagram shows two amino acids being joined together by a peptide bond.. When many amino acids join together a long-chain polypeptide is produced
Organic Compounds ‹ OpenCurriculum [8]
Organic compounds are chemical substances that make up organisms and carry out life processes. All organic compounds contain the elements carbon and hydrogen
Without carbon, life as we know it could not exist.. Why is carbon so important to organisms? The answer lies with carbon’s unique properties
Carbon atoms can form multiple stable bonds with other small atoms, including hydrogen, oxygen, and nitrogen. Carbon atoms can also form stable bonds with other carbon atoms
Organic compound | Definition & Examples [9]
Our editors will review what you’ve submitted and determine whether to revise the article.. – Charles Gerhardt Friedrich Wöhler Auguste Laurent Robert Burns Woodward Carl Wilhelm Scheele
organic compound, any of a large class of chemical compounds in which one or more atoms of carbon are covalently linked to atoms of other elements, most commonly hydrogen, oxygen, or nitrogen. The few carbon-containing compounds not classified as organic include carbides, carbonates, and cyanides.
All things on Earth (and most likely elsewhere in the universe) that can be described as living have a crucial dependence on organic compounds. Foodstuffs—namely, fats, proteins, and carbohydrates—are organic compounds, as are such vital substances as hemoglobin, chlorophyll, enzymes, hormones, and vitamins
Chapter 8: The Major Macromolecules [10]
Within all lifeforms on Earth, from the tiniest bacterium to the giant sperm whale, there are four major classes of organic macromolecules that are always found and are essential to life. These are the carbohydrates, lipids (or fats), proteins, and nucleic acids
In Chapter 6, you were introduced to the polymers of life and their building block structures, as shown below in Figure 11.1. Recall that the monomer units for building the nucleic acids, DNA and RNA, are the nucleotide bases, whereas the monomers for proteins are amino acids, for carbohydrates are sugar residues, and for lipids are fatty acids or acetyl groups.
You will find that the major macromolecules are held together by the same chemical linkages that you’ve been exploring in Chapters 9 and 10, and rely heavily on dehydration synthesis for their formation, and hydrolysis for their breakdown.. Figure 11.1: The Molecular building blocks of life are made from organic compounds.
Chemistry for Majors [11]
– Describe the structure and properties of an amine. – Describe the structure and properties of an amide
The nitrogen atom in an amine has a lone pair of electrons and three bonds to other atoms, either carbon or hydrogen. Various nomenclatures are used to derive names for amines, but all involve the class-identifying suffix –ine as illustrated here for a few simple examples:
A heterocyclic compound contains atoms of two or more different elements in its ring structure.. The genetic material for all living things is a polymer of four different molecules, which are themselves a combination of three subunits
Proteins [12]
Proteins are one of the primary constituents of living matter. They consist of long chains of amino acids, which are bonded together by peptide linkages and thus called polypeptides
Each amino acid contains a carboxylic acid end and an amino end. At a pH of 6-7 (the body’s pH is 7.3) the amino end is protonated, while the carboxylic end remains an anion; this is called a zwitterion
A peptide bond occurs when the carboxylic acid end of one amino acid bonds with. around the peptide bond, as well as the two carbon atoms to which the amino
A quick guide on Detection of C and H [13]
The detection of components contained in an organic compound is the first stage in its analysis. Carbon, hydrogen, and oxygen are the primary elements
Metals such as Li, Mg, and Zn can be found in organometallic compounds.. Quantitative analysis is a type of analysis that may be used to figure out how many elements or molecules are created during a reaction
Combustion analysis is the most popular way of detecting how much carbon and hydrogen are contained in a molecule. Combustion analysis involves burning a substance in the presence of pure oxygen, which yields solely carbon dioxide and water as products.
