Proteins are made up of amino acids, which are linked together in long chains. The sequence of amino acids in a protein determines its unique shape and function. Proteins can be classified into two main types: fibrous proteins and globular proteins.
- Fibrous proteins are long, thread-like proteins that provide structural support. Examples of fibrous proteins include collagen, which is found in skin, bones, and tendons, and keratin, which is found in hair and nails.
- Globular proteins are spherical or egg-shaped proteins that are involved in a wide range of biological functions, including metabolism, transport, and cell signaling. Examples of globular proteins include enzymes, which catalyze chemical reactions, and antibodies, which help to protect the body from infection.
Proteins are essential for life and play a vital role in building and repairing tissues. Without proteins, cells would not be able to function properly and the body would not be able to survive.

Proteins, in particular, are essential for providing structural support, facilitating movement, and carrying out a wide range of biological functions. This knowledge is essential for understanding the functioning of cells, tissues, and organs, as well as the overall health and well-being of living organisms.
Storage: Organic molecules, such as lipids, are used to store energy and form cell membranes.
Lipids are a diverse group of organic molecules that are insoluble in water but soluble in organic solvents. They are composed of carbon, hydrogen, and oxygen atoms, and often contain other elements such as nitrogen and phosphorus. Lipids serve two main functions in cells: energy storage and membrane formation.
Lipids are the primary energy reserve in animals and plants. They are stored in specialized organelles called adipose tissue. When the body needs energy, lipids are broken down into fatty acids and glycerol, which can then be used to generate ATP. Lipids are also used to store vitamins A, D, E, and K.
In addition to storing energy, lipids also play an important role in forming cell membranes. Cell membranes are composed of a phospholipid bilayer, which is a double layer of phospholipids. Phospholipids are lipids that have a hydrophilic (water-loving) head and a hydrophobic (water-hating) tail. The hydrophilic heads face outward, while the hydrophobic tails face inward. This arrangement creates a barrier that prevents water-soluble molecules from entering or leaving the cell.
Lipids are essential for life. They provide energy for cells, store vitamins, and form cell membranes. Without lipids, cells would not be able to function properly and life would not be possible.
The statement " Storage: Organic molecules, such as lipids, are used to store energy and form cell membranes" underscores the critical importance of lipids in the structure and function of living organisms. Lipids are essential for providing energy, storing vitamins, and forming cell membranes.
