"Protein" is not a specific molecule, but rather a class of molecules. The basic structure is an oligomer of beta-amino acids linked by amide bonds. Many proteins also incorporate cofactors or prosthetic groups.
Protein structure could also refer to the 3D conformation of the peptide backbone. The two most common regular structures in proteins are called the "alpha helix" and the "beta sheet", but it's difficult to describe these without pictures. If this is what you mean, consult any good biochemistry textbook.
Carboxyl group + amino group + side chain
Proteins contain chains of aminoacids.
The chains of smaller molecules that make up proteins are called amino acids. Each amino acid has a unique structure and side chain that determines the overall properties and function of the protein.
Yes, plants have carbon in their structure. Carbon is a key element in the molecules that make up plant cells, such as carbohydrates, proteins, and fats.
Amino acids make up proteins.
Phospholipids and cholesterol are two fat-based molecules that make up part of the structure of the plasma membrane. Phospholipids form a lipid bilayer, creating a barrier that separates the interior of the cell from the external environment, while cholesterol helps maintain the fluidity and stability of the membrane.
They are made up of RNA and proteins. mRNA refers to ribosomal RNA
The four top molecules that make up living things are carbohydrates, proteins, lipids, and nucleic acids. Carbohydrates provide energy and structural support, proteins perform a vast array of functions including catalysis and structure, lipids serve as long-term energy storage and make up cell membranes, and nucleic acids (DNA and RNA) are crucial for genetic information storage and transmission. Together, these molecules are essential for the structure and function of all living organisms.

Amino acids.
Proteins and lipids don't have cell membranes but are the molecules that make up the bulk of what a cell membrane is.
Phospholipids are the primary molecules that make up plasma membranes in cells. Other important molecules include cholesterol, glycolipids, and proteins. These components help maintain the structure and function of the plasma membrane.
