Study of Metabolic Processes

In this study of metabolic processes post we have briefly explained about carbohydrates, lipids, and proteins metabolic processes in human body.

Metabolic Processes in Human Body

The six elements oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus make up more than 99 percent of the human body. About 60% of the human body is made up of water, 15% of proteins, 15% of fats, 2% of carbs, and 8% of minerals.

The alphabet of biochemistry is made up of 30 tiny precursors that are used to build molecular structures in animals. Twenty amino acids, two purines, three pyrimidines, sugars (glucose and ribose), palmitate, glycerol, and choline make up this list.

Biomolecules in living creatures are arranged in a hierarchy of increasing molecular complexity. These biomolecules are covalently bonded to form cell macromolecules, such as glucose and glycogen, amino acids and proteins, and so on.

Proteins, polysaccharides, lipids, and nucleic acids are the most complex biomolecules. Non-covalent forces bring macromolecules together to form supramolecular systems like ribosomes and lipoproteins. Finally, diverse supramolecular complexes are formed into cell organelles at the greatest level of organisation in the cell structure hierarchy.

In prokaryotes (e.g. bacteria; Greek word “pro” = before; karyon = nucleus), these macromolecules are seen in a homogeneous matrix; but in eukaryotic cells (e.g. higher organisms; Greek word “eu” = true), the cytoplasm contains various subcellular organelles.

Carbohydrates, lipids, and proteins are the main elements of our food. These macromolecules must first be broken down into smaller pieces, such as monosaccharides for carbohydrates and amino acids for proteins.

Digestion, often known as primary metabolism, is a process that occurs in the gastrointestinal tract. The tiny molecules are further broken down and oxidised to carbon dioxide after absorption. NADH or FADH2 are produced during this process. Secondary or intermediary metabolism is the name given to this process.

Finally, these reducing equivalents enter the mitochondrial electron transport chain, where they are oxidised to water, trapping energy as ATP. Tertiary metabolism is the name given to this process. Metabolism is the sum of a compound’s chemical changes inside the body, including production (anabolism) and breakdown (catabolism) (catabolism).
