Structure of proteins

The structure and arrangement of polypeptide chains affects the spatial structure of proteins.

Anatomy of the small intestine

The longest part of the digestive system, where most of the digestion and absorption takes place.

Secondary structure of proteins

Polypeptide chains are composed of amino acids and can appear in alpha-helix or beta-sheet form.

ADP, ATP

ATP is the main source of energy for cells.

Coenzyme A

An acyl-carrier coenzyme taking part in both anabolic and catabolic processes.

Glands connected to the duodenum

The pancreas and the liver empty digestive juices into the duodenum.

Haemoglobin

Oxygen carrier protein in our red blood cells.

NAD⁺, NADP⁺, NADPH

NAD⁺ is a coenzyme that plays an important role mainly in catabolic processes, while NADP is important in anabolic processes as hydrogen carriers.
