you are what you eat crash course #3

What 3 molecules did Proutt believe were important in the diet?

Through his years of studying urine, Prout came to the conclusion that all foodstuffs fell into three categories: the saccharinous (carbohydrates), the oleaginous (the fats), and albuminous (the proteins).Feb 13, 2012

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.

What biological molecules does peanut butter contain?

When you get three fatty acid molecules together and connect them to a glycerol, that's a triglyceride. These feature prominently in things like butter, and peanut butter and oils and white parts of meat.

What are the 4 biomolecules?

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 proteins crash course?

Crash Course Review Recap Proteins are organic macromolecules built up of amino acids joined by peptide bonds. Amino acids are monomers made up of a carboxyl group, an amine group, and an R group attached to a central carbon. There are four increasingly complex levels of protein structure.Feb 14, 2022

What are lipids crash course?

Crash Course Review Recap Lipids are hydrophobic organic compounds that are divided into three main categories: fats, phospholipids, and steroids. Fats are composed of a glycerol and three fatty acids and are used for energy storage.Jul 16, 2020

What you eat belongs to biomolecules?

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.

Why biomolecules are important to human life?

Biomolecules are an organic molecule that includes carbohydrates, protein, lipids, and nucleic acids. They are important for the survival of living cells. Some of valuable biomolecules have huge demand, which cannot be fulfilled from their renewable resources.

What are the four macromolecules important to life?

There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids), and each is an important component of the cell and performs a wide array of functions.

What are the 5 biomolecules?

We have now been introduced to the major classes of biomolecules.carbohydrates.lipids.proteins.nucleic acids.

What a protein is?

Proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body's tissues and organs.Mar 26, 2021

What is the monomer of proteins?

amino acidsFor example, proteins are composed of monomers called amino acids. They are linked together to form a polypeptide chain, which folds into a three dimensional (3D) structure to constitute a functional protein (Figure 1).

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.
