Biomolecules

[This post takes 2 min.- 4 min. to read]

Hi!

First things first- the next post will be about chemistry-y stuff. Actually, I’m already working on it, but I just felt that I had to add a bio post before it. I’m sorry. It’s like I have a twisted inner compass that always points to bio like it’s the North pole or something. I don’t know. Bio rocks.

Anyways, let’s get this party[party?!] started!

What are biomolecules?

Biomolecules are molecules that are produced by living organisms. Biomolecules come in wide ranges of size and structure, and have a huge array of functions.

Types of biomolecules–>

  • Proteins- These are a type of large biomolecule that are also known as macromolecules(due to their large structures). Proteins are formed from sequences of amino acids.
  • Lipids- Lipids are a large subset of biomolecules and are characterized by their insolubility in water. Fats, a type of lipid, are made of glycerol and 3 fatty acids.
  • Nucleic Acids- Nucleic Acids are made from nucleotides, and nucleotides are made of thing like deoxyribose and nucleobase and other things I can’t pronounce and can barely spell. Nucleic Acids store and transfer cellular information.
  • Carbohydrates- Last, but not the least – carbohydrates.[Actually, the most abundant biomolecules are carbohydrates, so definitely not the least.] Living organsims use carbohydrates to fuel cellular reactions, and also to support cellular structure. Carbohydrates are also called saccharides, and are themselves made from monosaccharides.

Function of each biomolecule–>

Each biomolecule plays an important role in our body- and helps to keep us healthy and fully-functioning. Below is a very short, very abbreviated list of the functions of each biomolecule.

  • Proteins:
  1. They aid in transportation across cell membranes[above GIF. Rememeber? Channel and integral proteins…]
  2. Proteins help maintain proper pH in the body by regulating the amount of acids and alkalis present.
  3. Many proteins become chemical messengers that help communication between cells, tissues and organs to occur. These chemical messengers are known as hormones.
  • Lipids:
  1. Some cells use a type of lipid to communicate with each other.
  2. Lipids are used to make the outer layer of cells(the phospholipid bilayer…), and the myelin sheath segments that insulate neurons.
  3. Lipids can also be used as a supply and store of energy for the body.
  • Nucleic Acids:
  1. They store and express genetic information.
  2. Some of these acids differ in molecular structure and participate in protein synthesis.
  • Carbohydrates:
  1. They provide energy to the body.
  2. Glucose from carbohydrates is particularly important in helping the brain function.
  3. They provide support in the cellular structure

Enzymes–>

The above picture is not a very tangled ribbon. It’s actually an enzyme.

Enzymes are really important little guys. They are biological catalysts– which means that they boost the rate of a biochemical reaction while remaining unchanged.

Now, the reason I included this here is because enzymes are crucial to the breakdown of biomolecules, and this is particularly handy when it comes to digestion.

For example, protease and pepsin are both enzymes that split a protein into little peptides. Lipase helps to break down fats like lipids into monoglycerides and fatty acids. Maltose sugars are formed when an enzyme, amylase, breaks down starch- which is a carbohydrate.

I just included enzymes here because like, since you guys know what a biomolecule is made up of, it would be cool to know what breaks them down too…

Anyways, here’s your Space Bonus- https://www.youtube.com/watch?v=B7q0Z19sKdM

It’s a video about galaxy shapes and what they mean. Hope you enjoy it!

Thanks and bye!
