biological molecules - you are what you eat: crash course biology lesson

What are the three main biological molecules we eat?

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.

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 you eat belongs to biomolecules?

What makes food? All organic (naturally occurring) molecules are classified into 4 general categories: carbohydrate, lipid, protein, and nucleic acid. Foods you consume consist of these 4 molecules.

What happens to the biological macromolecules in the food we eat?

As food travels through your digestive system – in fact, from the moment it hits your saliva – it is being worked over by enzymes like these. The enzymes break down large biological molecules, releasing the smaller building blocks that can be readily absorbed and used by the body.

What does you are what you eat meaning biology?

Λ Φ Ω Σ 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.

Why is it important to learn about biological molecules?

These molecules perform or trigger important biochemical reactions in living organisms. When studying biomolecules, one can understand the physiological function that regulates the proper growth and development of a human body.

What are biological molecules?

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.

What are bio molecules give examples?

Explanation: The lifeless, complex organic molecules which combines in a specific manner to produce life or control biological reactions are called biomolecules. Examples => Carbohydrates, lipids (fats and oils), nucleic acids, enzymes.Oct 9, 2018

What is food Why do we eat food?

A food is something that provides nutrients. Nutrients are substances that provide: energy for activity, growth, and all functions of the body such as breathing, digesting food, and keeping warm; materials for the growth and repair of the body, and for keeping the immune system healthy.

Why are biological macromolecules important in everyday life?

Gigantic molecules, called macromolecules, populate a cell and provide it with important functions for life. For example, macromolecules provide structural support, a source of stored fuel, the ability to store and retrieve genetic information, and the ability to speed biochemical reactions.

What happens to macromolecules from food during digestion?

Chemical digestion is the biochemical process in which macromolecules in food are changed into smaller molecules that can be absorbed into body fluids and transported to cells throughout the body. Substances in food that must be chemically digested include carbohydrates, proteins, lipids, and nucleic acids.Mar 25, 2019

What biological macromolecules you might get from meat?

Proteins: a. Beans, meat, green leafy vegetables b. Necessary to maintain muscles c. Proteins are part of almost everything in our bodies – (reaction catalysts, antibodies, hair, nails, muscle tissue, support of cells, “traffic cops” across cell membranes) 4.

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.

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.

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.

What is Hank's talk about?

What are lipids made of?

Lipids are made up of the same elements as carbohydrates: carbon, hydrogen, and oxygen. However, lipids tend to contain many more hydrogen atoms than oxygen atoms.

What does polarity mean in chemistry?

Polarity means one end is positive and the other is negative. For example in phospholipids, the phosphate is positive and the other side is negative. The negative side avoids water, so the molecule doesn't mix well. Solubility is how well something mixes, so there is your answer.

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 happens when carbohydrates start to become longer chains?

Instead of being sources for instant energy, they become storehouses of energy or structural compounds. These are the polysaccharides. Instead of being just two or three monosaccharides put together, polysaccharides can contain thousands of simple sugar units. And because they’re so big and burly, they’re great for building with.

Why are fats and lipids grouped together?

All of our mom’s worst enemies, the fat, which turn out to be, actually, really important, and are the most familiar sort of a very important biological molecule, the lipid.#N#Lipids are smaller and simpler than complex carbohydrates, and they’re grouped together because they share an inability to dissolve in water. This is because their chemical bonds are mostly non-polar. And since water, as we learned in the previous episode, despises non-polar molecules, the two do not mix. It's like oil and water. In fact, it's exactly like oil and water. And if you’ve ever read a nutrition label, or seen this thing called the television, you're probably pretty conversant in the way that we classify fats. But then, you know, 99% of us have no idea what those classifications actually mean.

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.

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.

Why are Omega 3 fats important?

But the reason why these are important is because we can't synthesize them ourselves. They're essential fatty acids, meaning that we need to eat them in order to get them.

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.
