The molecule in this image is an amino acid which are the building blocks of proteins.
amino acid are organic molecules that contain a nitrogen atom, a carbon atom, a hydrogen atom, a carboxyl group, and an amino group . The side chain (R group) is the only part that differs between amino acids. It can be a simple hydrogen atom or a complex molecule like a benzene ring.
There are 20 different amino acids that are used to make proteins in the human body. Each amino acid has a unique side chain, which gives the protein its unique properties. For example, the side chain of the amino acid cysteine can form disulfide bonds, which give proteins their strength and structure.
Amino acids are used to build and repair tissues, produce hormones and enzymes, and transport nutrients throughout the body.
