How are Carbohydrates, lipids and proteins related?

Answer 1

They are all biological molecules and they are all found in living cells, where they assume diverse functions.

Proteins are a class of molecules made of amino-acids. There are 20 different amino-acids in total, and a protein is a linear chain of ~50 or more amino-acids. The chemical and physical properties of the amino-acids result in each protein having a specific fold, or a shape in space.
Proteins are the main actors of biological reactions and have various roles: they can be enzymes, transporters, hormones, antibodies, etc...

Carbohydrates are a class of molecules related to sugars. They are made of monosaccharide units, the most common being glucose, fructose, galactose, mannose, glucosamine, sialic acid... they can be either linear chains or branched structures of very diverse sizes.
Carbohydrates have two kinds of functions:
- energy: glucose, saccharose, fructose are simple carbohydrates with an immediate energetic role. Starch and glycogen are two large molecules (polymers) used for storage of energy.
- molecular binding and communication: carbohydrates are also found to be bound to lipids and proteins and to cell surfaces, where they modulate the interaction with the environment.

Lipids are a highly heterogenous class of molecules, all characterised by hydrophobic properties, ie it is fat.
Lipids serve as energy storage and also are the main component of cell membranes. Cholesterol, (saturated or unsaturated) fatty acids, phospholipids are all lipids.

All these molecules are made of the same basic elements: Carbon, Hydrogen, Oxygen, Nitrogen assembled in various ways. They are all necessary for life and found in the lowest unicellular organisms as well as in higher eukaryotes like animals and plants. We can synthesise some, but not all of their constitutive elements by ourselves, and must take the rest from food (e.g omega 3 and omega 6 fatty acids or certain amino acids).

Answer 2

the are "organic" molecules found in living organisms and have similar carbon atom skeletons. Carbohydrates have an excess of hydroxyl and hydrogen side groups, lipids have long carbon-hydrogen chains confer insolubility and proteins are long chains of monomeric amino acids that have a nitrogenous backbone and up to 20 (in nature) side chains that vary in chemical character.

Answer 3

All three of these compounds can be converted to energy by the body. All get broken down (catalyzed) into glucose by processes such as hydrolysis (carbohydrates) decarboxylation (lipids and fats) and deaminization (proteins and amino acids).

Answer 4

they are all types of energy that come from our food supply. carbohydrates make up the bulk of our energy and is what we use readily followed by fats this is why fatty foods make you put on weight. your body uses the carb stores first and if that is adequate fat gets stored as adipose fat under the skin. proteins are a type of energy the body uses to make and repair the cells of the body. also the last resort for energy. body does not like using proteins for energy as it is a lot harder to break down into the energy required.
hope that has answered your question and that it is as acurrate as poss.

Answer 5

They are all made up of the elements Carbon(C) ,Hydrogen (H) and Oxygen (O).
Carbohydrates are made of- C,H,O
Lipids are made of- C,H,O- bt they ofcause have a different structure from the structure of carbohydrates
Proteins are made of- C,H,O and Nitrogen(N)

Answer 6

Wow i forgot but im guessing carBohYdrate i didnt hear a question like this ever since high school

Answer 7

carbs,lipids and proteins have carbon and hydrogen in common.the no of carbon and hydrogen in the compound 'decides' wheter it is a carb.protein or lipids.

Answer 8

They are 3 of the 4 biomolecules...the fourth being Nucleic acids. THEY ALL WORK TOGETHER!!!

Answer 9

They are all organic molecules - meaning they are all carbon based.
