defination of fats and their types
Answers
Fats are one of the three main macronutrients, along with carbohydrates and proteins. Fat molecules consist of primarily carbon and hydrogen atoms and are therefore hydrophobic and are soluble in organic solvents and insoluble in water. Examples include cholesterol, phospholipids, and triglycerides.
Fat is a term used to describe a class of macro nutrients used in metabolism called triglycerides. These make up one of three classes of macronutrients including proteins and carbohydrates. Fats provide a means of storing energy for most eukaryotes, as well as act as a food source. Fats have the highest energy storage potential of the macronutrients, and are very chemically stable, making them ideal for storing energy for later use. Macronutrients does not refer to the size of the molecule, but to the amount needed to sustain life. Vitamins and minerals are considered micronutrients.
Fat is organized into two subgroups: saturated fat, and unsaturated fat. Unsaturated fat is further classified as monounsaturated fat, polyunsaturated fat, and trans-fat. These different classifications determine the effects of these fats on an organism, and the roles that they have in metabolism.
