The element present in all amino acids but not necessary in fats or carbohydrates is nitrogen. Amino acids, the building blocks of proteins, contain an amino group (-NH2) that includes nitrogen. In contrast, fats and carbohydrates are primarily composed of carbon, hydrogen, and oxygen, without the inclusion of nitrogen in their structures.
Phosphorus complexes are present in proteins but is not present in sugars or fats..
Nitrogen is the element present in all proteins except carbohydrates and fats. Amino acids make up all proteins, and they contain the amino group NH2, except for carbohydrates and fats.?æ
Proteins contain nitrogen, which is not present in carbohydrates.
Nitrogen
The element present in all large macromolecules in the human body is carbon. Carbon is fundamental to the structure of carbohydrates, proteins, lipids, and nucleic acids, as it forms the backbone of these molecules. Its ability to form stable bonds with various elements allows for the complex structures necessary for biological functions.
Nitrogen
Nucleic acids contain sugar, phosphate groups, and nitrogenous bases, which are not present in carbohydrates or amino acids. They are the building blocks of DNA and RNA, playing a crucial role in genetic information storage and transfer.
aliphatic, alicyclic, aromatic and heterocyclic compounds.
Hydrogen
The key element found in all carbohydrates, lipids, proteins, and nucleic acids is carbon. Carbon's ability to form four covalent bonds enables it to create complex molecules essential for life, including the diverse structures and functions of these macromolecules. In addition to carbon, hydrogen and oxygen are also commonly found in carbohydrates and lipids, while nitrogen and phosphorus are present in proteins and nucleic acids, respectively.
phosphorus is present in nucleic acids and not in proteins
