What are the differences between carbohydrates lipids or protein?

Answer 1

A lipid is: 1) a hydrophobic hydrocarbon (meaning: a usually very large molecule that doesn't like water (hydrophobic) and is made up of carbon (C) and hydrogen (H))If you try to mix oil and water the two don't mix. 2) Lipids are not made from small subunits to make a long molecule (called a polymer)- lipids are not polymers.

The class of lipids most important to Biology are: 1) Fats, 2) phospholipids (cell membranes are composed of this lipid), 3) steroids (testosterone for example), and to a lesser degree wax. There are many other types of lipids.

Carbohydrates are: hydrophilic (water liking) molecules that consist of different combinations of CH2O (carbon, hydrogen and oxygen) in that arrangement. 2) these molecules form polymers from simple subunits.

Classes of Carbohydrate: Sugar (sucrose is table sugar, glucose used in respiration), starch (made by plants), glycogen (storage sugar made by humans in the liver and muscle), cellulose (structural component in plant stems)... there are more but these are the important ones.

The difference between Carbohydrates (sugars) and Lipids:

1) sugars disolve in water lipids don't

2) sugars are made-up of subunits that form large polymers and lipids are not and don't form polymers.

3)Lipids store more energy than sugars.

4) sugars form stuctural components (cellulose in plants) and lipids form bountaries like the cell membrane due to hydrophobic hydrocarbons.

Answer 2

Carbohydrates (from 'hydrates of carbon') or saccharides are the most abundant of the four major classes of biomolecules. They fill numerous roles in living things, such as the storage and transport of energy (eg: starch, glycogen) and structural components (eg: cellulose in plants, chitin and cartilage in animals). Additionally, carbohydrates and their derivatives play major roles in the working process of the immune system, fertilization, pathogenesis, blood clotting, and development.

Lipids are broadly defined as any fat-soluble (lipophilic), naturally-occurring molecule, such as fats, oils, waxes, cholesterol, sterols, fat-soluble vitamins (such as vitamins A, D, E and K), monoglycerides, diglycerides, phospholipids, and others. The main biological functions of lipids include energy storage, acting as structural components of cell membranes, and participating as important signaling molecules.

Answer 3

Carbohydrates are found in fruits like apples for example as to where lipids would be found in oils for example.
