MACROMOLECULES

PROTEINS

• Proteins help you build up muscles.
• They are worker molecules that are necessary for virtually every activity in the body.
• They circulate in your blood,seep from your tissues, and grow in longs strands out of your head.
• They are the key components of biological materials ranging from silk fibers to elk antlers.
• Proteins come in all shapes and sizes.

PROTEINS

• Proteins have diverse roles in the body.
• They also help us understand diseases
• Caused by abnormal proteins, which deposits inside brain cells
• Causing frontotemporal degeneration.

CHEMICAL COMPOSITION OF PROTEINS

• Proteins are made up of subunits called amino acids.
• Each amino acid has an alpha-amino, alpha carboxyl and an alpha carbon. An R group is what differs from the amino acids.
• An R group can be a polar or non-polar or positive or negative charged. The properties of the amino acid chains will determine how the amino acid chain will fold.

FUNCTION

• Serve as enzymatic
• Used to transport molecules
• Can bind and release other molecules
• They do most of the work in cells.

ITS FUNCTION IN A LIVING ORGANISM

• Catalyze chemical reactions
• They are also necessary in animal diets because animal are not able to revive all the amino acids they need.
• Cell signaling and signal transduction
