A Few Functions Of Proteins:
1. They help to make up part of the structure of our bodies.
2. They can work as enzymes to help a particular chemical reaction take place or speed up a chemical reaction.
3. Essential body processes such as water balancing, nutrient transport, and muscle contractions require protein to function.
4. Proteins can be used as energy if there isn't enough energy from carbohydrates.
A Few Examples Of Proteins:
Enzymes are proteins but some foods made up of a lot of proteins are meat, milk and dairy products, fish, eggs, and peanut butter.

Enzymes such as amylase and catalase are functional proteins that catalyze biochemical reactions. Hemoglobin is a functional protein that carries oxygen in red blood cells. Antibodies are functional proteins that help the immune system identify and neutralize pathogens.
Functional proteins carry out a function in the body unlike structual proteins which produce structures (eg bones and muscles). An example of a functional protein is antibodies as they carry out the function of fighting off bacteria and virus'. Another example is hemoglobin which transports oxygen around the body.
Storage molecules, transport molecules, and movement.
Proteins are composed of various functional groups, including amino (-NH2), carboxyl (-COOH), hydroxyl (-OH), sulfhydryl (-SH), and phosphate (-PO4). These groups are involved in forming peptide bonds, stabilizing protein structure, and participating in various biochemical reactions.
Proteins are nitrogenous compounds being made up of carbon, hydrogen, oxygen and nitrogen. Proteins also contain sulphur. In living systems proteins play an important role in the structural organisation eg., cell membrane, hairs, nails and muscles. Many of the proteins serve as enzymes. They are named as functional proteins.
A hormone is an example of a signaling protein, which is a functional class of proteins that transmit information within the body to regulate physiological processes.
Examples of proteins include enzymes (such as amylase, catalase), structural proteins (such as collagen, keratin), transport proteins (such as hemoglobin, albumin), and antibodies.
