Compounds can be classified as ionic or covalent. Molecules are the simplest unit of a covalent compound, and molecules can be represented in many different ways. Atoms are the smallest units of matter that still retain the fundamental chemical properties of an element.

Proteins, carbohydrates, nucleic acids, and lipids are the four major classes of biological macromolecules—large molecules necessary for life that are built from smaller organic molecules. Macromolecules are made up of single units known as monomers that are joined by covalent bonds to form larger polymers.

Biological macromolecules are large molecules, necessary for life, that are built from smaller organic molecules. There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids); each is an important cell component and performs a wide array of functions.

A molecule is the smallest particle of a substance that exists independently. Molecules of most elements are made up of only one of atom of that element. Oxygen, along with nitrogen, hydrogen, and chlorine are made up of two atoms.

Characteristics. All molecules have a definite mass and size that are dependent on the atoms from which the molecule is made. The mass is equal to the sum of the masses of all the individual atoms in the molecular structure.

Molecular formulas describe the exact number and type of atoms in a single molecule of a compound. The constituent elements are represented by their chemical symbols, and the number of atoms of each element present in each molecule is shown as a subscript following that element's symbol.

1). All compounds are molecules, but not all molecules are compounds (if they happen to have atoms of the same element). Diatomic molecules are molecules composed of only two atoms of either the same or different elements. ... However, not every diatomic molecule comprises a chemical compound.

Lipids are a class of macromolecules that are nonpolar and hydrophobic in nature. Major types include fats and oils, waxes, phospholipids, and steroids.

Compound Basics Every combination of atoms is a molecule. A compound is a molecule made of atoms from different elements. All compounds are molecules, but not all molecules are compounds. Hydrogen gas (H2) is a molecule, but not a compound because it is made of only one element.

There are four classes of macromolecules that constitute all living matter: carbohydrates, lipids, proteins, and nucleic acids. While they have different structures and functions, they are all composed of long complex chains of molecules (polymers) made up of simpler, smaller subunits (monomers).

D. Living things are made of four types of molecules, known as macromolecules. These macromolecules are proteins, nucleic acids (DNA and RNA), lipids (fats) and carbohydrates.

Molecules are groups of two or more atoms, but there is a special sub-group of molecules, too. These are compounds, and a compound is a group of two or more different atoms chemically bonded together. The key here is that compounds are made of at least two different elements.

Organic molecules are molecules that contain carbon atoms, which are covalently bonded together. ... Carbon and hydrogen can come together in different ways and can form many, many distinct molecules, which are collectively called hydrocarbons. Hydrocarbons are molecules that are made of hydrogen and carbon atoms.

All organisms are made of four types of carbon-based molecules: carbohydrates, lipids, proteins, and nucleic acids.

In a molecule, atoms are bonded together by single, double, or triple bonds. An atom has a nucleus surrounded by electrons. ... So another difference between atoms and molecules is that when similar atoms combine together in varying numbers, molecules of different properties can be formed.
