Classify each as carbohydrate, protein, lipid, or nucleic acid.
1. Starch
2. Cholesterol
3. Steroids
4. Glycogen
These are my answers, can someone please check them for me?
1. Carbohydrate
2. Lipids
3. Lipids
4. Carbohydrate
I agree with all of your answers.
1. Starch: Carbohydrate
2. Cholesterol: Lipid
3. Steroids: Lipid
4. Glycogen: Carbohydrate
To determine the classification of each substance, we need to understand the characteristics of carbohydrates, proteins, lipids, and nucleic acids.
1. Starch: Starch is a complex carbohydrate. Complex carbohydrates are made up of long chains of sugar molecules. Starch is commonly found in plants, such as potatoes and grains.
2. Cholesterol: Cholesterol is a lipid. Lipids are molecules that are insoluble in water but soluble in organic solvents. They include fats, oils, and cholesterol. Cholesterol is a waxy, fat-like substance found in all cells of the body and is essential for the production of hormones, Vitamin D, and bile acids.
3. Steroids: Steroids are a type of lipid. They are composed of four carbon rings and are involved in various physiological processes. Steroids include hormones such as estrogen and testosterone, as well as cholesterol (mentioned above).
4. Glycogen: Glycogen is a complex carbohydrate. It is the storage form of glucose in animals, including humans. Glycogen is stored in the liver and muscles and is broken down into glucose when energy is needed.
In summary:
1. Starch - Carbohydrate
2. Cholesterol - Lipid
3. Steroids - Lipid
4. Glycogen - Carbohydrate
