you are what you eat: crash course biology #3 questions

How does the phrase you are what you eat relate to biological molecules?

Hank talks about the molecules that make up every living thing - carbohydrates, lipids, and proteins - and how we find them in our environment and in the food that we eat. Created by EcoGeek.

What biological molecule is in peanut butter?

When you get three fatty acid molecules together and connect them to a glycerol, that's a triglyceride. These figure prominently in things like butter, and peanut butter, and oils, and the white parts of meat. These triglycerides can either be saturated or unsaturated.

What you eat belongs to biomolecules?

1. Carbohydrates – sugars, starches (flour), grains. Carbohydrates can be found in almost all food sources. Rice, cereal, potatoes, fruits, pasta, vegetables, etc., have some kind of carbohydrate in them.

What are the four biological molecules which three does this video focus on?

And we've talked about water and now we're going to talk about the molecules.

What does peanuts do to a female body?

The benefits of peanuts sexually for females. Peanuts offer folate, a nutrient essential to the female reproductive system and one that is difficult to get from food sources. This is why peanuts are of particular benefit to women. They're also a source of biotin, which is a key nutrient to women during pregnancy.

What biological molecule is bread?

Fortunately, the yeast used in bread-making contains the enzyme maltase, which breaks maltose into glucose. When the yeast cell encounters a maltose molecule, it absorbs it. Maltase then bonds to the maltose and breaks it in two.

What does you are what you eat mean in biology?

You Are What You Eat is the idea that organisms that consume food via phagocytosis, particularly single-celled organisms that engulf other organisms, that are able to obtain genetic information from that food.

Which food molecule would you eat?

What are macromolecules in food?

Macromolecules are very large molecules created by the polymerization of small units called monomers. Most of the macromolecules are present in everyday life, for instance, in food. There are several types of biological macromolecules: Carbohydrates, Proteins, Lipids and Nucleic acids.

Is a nucleic acid DNA or RNA?

The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the master blueprint for life and constitutes the genetic material in all free-living organisms and most viruses.

What are the 4 main biomolecules?

biomolecule, also called biological molecule, any of numerous substances that are produced by cells and living organisms. Biomolecules have a wide range of sizes and structures and perform a vast array of functions. The four major types of biomolecules are carbohydrates, lipids, nucleic acids, and proteins.

Is DNA a biomolecule?

A biomolecule refers to any molecule that is produced by living organisms. As such, most of them are organic molecules. The four major groups of biomolecules include polysaccharides, proteins, nucleic acids (DNA and RNA), and lipids. They are found in and produced by living organisms.

What are macronutrients?

Direct link to Paul Vinell's post “Macronutrients are nutrie...”. more. Macronutrients are nutrients that provide energy; proteins, fat and carbohydrates. Fat does not just provide us with energy, it's used in vitamin absorption, your brain, your cells, hormones, hair, skin, etc.

What enzyme breaks down cellulose?

So throw that on some cellulose in an ionic solution, and cellulose will break down into its components, i.e. D-glucose.

Why is fat important?

They are important for your body to function. Fat does not make you fat by itself. An excess amount of anything that provides you with energy, will be stored as fat, so you can use the energy later. Fat can be stored as fat, just like carbohydrates and protein can.

Can cellulose be converted to starch?

There is no way to directly convert cellulose to starch (like simple mutarotation). However, there are a few multi-step chemical processes that could be utilized to turn cellulose into starch, and, of course, enzymes that catalyze each reaction step.

What are the ingredients of life?

They are the ingredients for life, and we call them the carbohydrates, the lipids, the proteins, and the nucleic acids.

What are carbohydrates made of?

Carbohydrates are made up of sugars, and the simplest of them are called monosaccharides. "Mono" for one, "saccharides" for the actual root of the word sugar. The star of the show here is glucose, because it’s truly fundamental, by which I mean, like, number one on the global food chain, because it comes from the sun.

How are amino acids formed?

Amino acids form long chains called polypeptides. Proteins are formed when these polypeptides not only connect but elaborate and, frankly, really elegant structures. They fold. They coil. They twist. If they were sculptures, I would go the museum every day just to look at them, and I'd walk straight past the nudes without even looking.#N#But protein synthesis is only possible if you have all of the amino acids necessary, and there are nine of them that we can't make ourselves: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. By eating foods that are high in protein, we can digest them down into their base particles, and then use these essential amino acids in building up our own proteins. Some foods, especially ones that contain animal protein, have all of the essential amino acids, including this egg.

What is the process of getting energy from glucose?

And every cell that needs energy uses glucose to get that energy through a process called respiration. In addition to glucose, there are other monosaccharides like fructose, which has the same molecular formula (C 6 H 12 O 6) but arranged differently. These subtle chemical differences do matter.

What are the two main ingredients in fat?

Fats ( 07:47) Fats are made up mainly of two chemical ingredients: glycerol, which is a kind of alcohol; and fatty acids, which are long carbon-hydrogen chains that end in a carboxyl group. When you get three fatty acid molecules together and connect them to a glycerol, that’s a triglyceride.

Can cows digest cellulose?

Unfortunately, it's very difficult to digest. Cows can do it, but humans certainly can not, which is why you don' t enjoy eating grass.

Who was the first person to understand the body?

His name was William Prout, and in the early 1800s, he became fascinated with human digestion, especially our urine. And that’s because he thought that the best way to understand the human body was through chemistry, and the best way to understand the body's chemistry was to understand what it does to food.
