Question

The macromolecules in biochemistry are proteins, carbohydrates, lipids and nucleic acids. What main elements do all of have in common?

Answer 1

Carbon
Oxygen
Hydrogen

A macromolecule is a large molecule. There are four groups of macromolecules: carbohydrates, proteins, nucleic acids and lipids. Lipids consist of glycerol and fatty acids and are constructed from fats, oils, waxes, phospholipids and steroids. A lipid's function is to insulate the body and provide warmth in cold conditions. It can be concluded that a person with very little body fat gets very cold easily and a person with a lot of body fat gets very warm very quickly.

Answer 2

The mains elements that they all have is ; Carbon, hydrogen, and oxygen;

Explanation;
The major macro-molecules in biochemistry are proteins , lipids, carbohydrates and nucleic acids. They all have common elements which are hydrogen, carbon and oxygen.
Proteins; these are polymers which are made from amino acids molecules joined together by peptide bonds. Each Amino acid; contains a carboxyl (-COOH) group which has a carbon,oxygen and hydrogen elements.
Carbohydrates; are energy sources that are derived from simple sugars (monosacchrides) such as glucose; (C6H12O6) which contains hydrogens, carbon and oxygen atoms.
Lipids; these are made from fatty acids (R-COOH) and glycerol (C3H8O3); which also contain carbon, hydrogen and oxygen atoms.
Nuclei acids on the other hand contains nitrogenous bases, sugars, and phosphates; the nitrogenous bases; contain nitrogen, and hydrogen atoms, sugars contain , hydrogen, carbon and oxygen atoms; phosphates contain both phosphorus and oxygen atoms.
