what converts oils into soild fats

hydrogenation

glycolipids

phospholipids

lipids

• all biological compounds that are not soluble in water

  but are soluble in organic solvents

functions of lipids

1. lipids function as part of the structure of cell membranes,

2. as energy storage molecules for the cell,

3. and the starting material for the synthesis of vitamins and hormones.

lipid storage

storage is an important function of lipids. Energy stored in the fats in our body is more important than the glycogen storage. The burning of fats produces twice as much

energy as the burning of carbohydrates

lipid membrane components

➢ Lipids form the membranes around body cells and around small structures inside the cell.

➢ The purpose of these lipids is to separate cells from the external environment and provide selective transport for nutrients and waste products.

lipid chemical messengers

Cholesterol is the starting material for the synthesis of steroid hormones.

State the components of cell membranes and the fluid mosaic model

phospholipids, proteins, cholesterol, and carbohydrates. The fluid mosaic model describes the membrane as a dynamic structure where these components are free to move within the bilayer, creating a fluid-like mosaic

steroid

Know the properties of cholesterol

waxy, fat-like substance essential for various bodily functions, including cell membrane structure, hormone synthesis, and vitamin D production. It's a sterol, a type of lipid, and exhibits both hydrophilic and hydrophobic properties due to its unique structure. It's primarily found in animal tissues and is also produced by the liver
