what are the structural differences between proteins and carbohydrates?
475516
Proteins consist of units called amino acids, strung together in complex formations. Because proteins are complex molecules, the body takes longer to break them down. As a result, they are a much slower and longer-lasting source of energy than carbohydrates. There are 20 amino acids.

Simple carbohydrates include monosaccharides and disaccharides. The monosaccharides glucose, fructose, and galactose are single sugar molecules. The disaccharides sucrose, lactose, and maltose are double sugar molecules. Complex carbohydrates are chains of more than two sugar molecules.

Glycolipid refers to lipids with a carbohydrate attached by a glycosidic (covalent) bond while glycoprotein refers to any of a class of proteins which have carbohydrate groups attached to the polypeptide chain. Thus, this is the main difference between glycolipids and glycoproteins.

The main difference between simple and complex carbohydrates is that simple carbohydrates are quickly digested and absorbed by the body whereas complex carbohydrates take time to be digested.

What's the difference between simple and complex carbohydrates? Simple carbs break down easier and contain sugars. Complex carbs contain starch and fiber. ... Fibers added to foods.

Differences: Lipid molecules contain more energy per gram than carbohydrates (about twice as much) ... Carbohydrates are stored as glycogen in animals while lipids are stored as fats (in plants carbohydrates are stored as cellulose and lipids as oils)

Carbohydrate. any of a large group of organic compounds occurring in foods and living tissues and including sugars, starch, and cellulose. Monosaccharide. any class of sugars that cannot be hydrolyzed to give a simpler sugar.

The main difference between macronutrients and micronutrients is that human body requires macronutrients in larger quantities whereas micronutrients are needed in smaller quantities. The major macronutrients are carbohydrate, protein and fat which contribute to the bulk of our food.

Also, they are both organic substances, having lots of carbon-hydrogen bonds. The difference is that lipids contain fatty acids and glycerol, while proteins contain amino acids, which have nitrogen.

Simple sugars, known as monosaccharides, are the building blocks of carbohydrate polymers. Unlike DNA, RNA, and proteins which are linear polymers, carbohydrates are formed by both linear and branched combinations of a wide variety of naturally occurring monosaccharides.

As nouns the difference between glycogen and glycerol is that glycogen is (carbohydrate) a polysaccharide that is the main form of carbohydrate storage in animals; converted to glucose as needed while glycerol is glycerol.

In short, fibre and starch are complex carbohydrates, while sugar is a simple carb. How much of each of these you eat determines its nutrient quality. The more fibrous the carbohydrate the better it generally tends to be.

Carbohydrates, or carbs, are sugar molecules. Along with proteins and fats, carbohydrates are one of three main nutrients found in foods and drinks. Your body breaks down carbohydrates into glucose. Glucose, or blood sugar, is the main source of energy for your body's cells, tissues, and organs.

Complex carbohydrates contain longer chains of sugar molecules than simple carbohydrates. The body converts these sugar molecules into glucose, which it uses for energy. As complex carbohydrates have longer chains, they take longer to break down and provide more lasting energy in the body than simple carbohydrates.

Which statement correctly identifies a difference in the structure of proteins and polysaccharides? Only polysaccharides are comprised of repeating units of cytosine, adenine, guanine, and thymine. Only proteins are formed from amino acids joined by peptide bonds.
