Chemistry. Online. — free course from Sciencely. Smart Moscow, training 1 month, Date: December 4, 2023.

An employee of the International Research Institute of Smart Materials of Southern Federal University, Polina is a chemist to the core. By the way, about bones: if you lose support from your native body, then very soon hospitals will offer you a bone implant from substances carefully synthesized by Polina. And we’ll give some advice to avid travelers: on your next flight, don’t forget to open the in-flight magazine “Your Azimuth,” where Polina put her hands and heart into creating a science column for children.

5th year student of the Department of Enzymology, Faculty of Chemistry, Moscow State University named after M.V. Lomonosov. Maria's scientific activity is related to the search for new and the study of already known enzyme inhibitors that contribute to a more effective fight against cancer. By the way, the enzymes that Maria also works with are bright representatives of the nanoworld. For several years I managed to work at the Polytechnic Museum as a guide and as an employee of the biohacking laboratory, and now I give all my love for science to the participants of our circles.

Graduate of the Faculty of Chemistry of Moscow State University, employee of the Laboratory of Fine Organic Synthesis of Heterocyclic Compounds. Previously, Svyat worked on the creation of libraries of structures aimed at combating cancer tumors, and now he is engaged in the synthesis and optimization of drugs.

After completing the first module, you will have the opportunity to enroll in the second [lessons 13−24]

LESSON 1. SIGNS OF CHEMICAL REACTIONS.

Let's get to know not only each other, but also the safety rules. Let's carry out chemical reactions in which a precipitate falls, gas is formed, heat is released, and color changes. All these changes are called signs of chemical reactions.

LESSON 2. IONS.

Let's figure out why some salts react when mixed and some don't. Let's get to the very essence and learn about ions - the particles that make up any salt. Let us confirm experimentally: salts with the same ions enter into the same reactions, and knowledge of the properties of chemical substances helps to establish the composition of unsigned reagents.

LESSON 3. ACIDS AND INDICATORS.

Not only salts, but also acids are made of ions. Let's find out that the acidity of the product depends on the amount of special “acidic” ions - hydrogen ions. Let's determine the amount of hydrogen ions in food using a universal acid-base indicator. Let's get acquainted with other indicators and their scale.

LESSON 4. PAINTS.

Most often, a person deals with solutions of substances. Not all substances dissolve in water, but man has found a use for them. Let's figure out what pigments are and what dyes were made from in ancient times. We independently synthesize inorganic pigments and create our own paints.

LESSON 5. STRUCTURE OF SUBSTANCE.

Let's get acquainted with the structure of chemical substances, talk about chemical bonds and figure out why salt cannot be called a molecule. We will collect three-dimensional models of the molecules that make up air, as well as a model of graphite and other chemical structures.

LESSON 6. POLYMERS.

Let's understand the structure of wood and plastic and find out what they have in common. Let's talk about polymers and their role in our lives. We will mark the plastic, create a polymer product and an adhesive mass ourselves. Let's break down one polymer (starch) with the help of another polymer (enzyme).

LESSON 7. CARBOHYDRATES.

All living things, including you and me, are also chemistry. Let's figure out what molecules we are made of and what we eat. The lesson will focus on carbohydrates. Let's prepare Benedict's reagent and learn how to make a qualitative reaction to glucose, and then check the glucose content in honey and in a starch solution that is destroyed by the enzyme.

LESSON 8. PROTEINS.

We continue to dive into the chemistry of biopolymers. The lesson will be devoted to proteins. We will learn to experimentally distinguish wool fibers from synthetics and get acquainted with one of the methods of taking fingerprints.

LESSON 9. CHEMISTRY FROM THE FIRST KIT.

Let's dive into medicinal chemistry and learn about the structure and mechanisms of action of medicinal substances. Let's experiment with the contents of the first aid kit: learn about the cleansing properties of activated carbon and use it to create a filter for water, determine the acidity using brilliant green, carry out qualitative reactions with commonly used tablets (paracetamol, aspirin).

LESSON 10. VITAMINS.

Let's talk about vitamins - another important class of biomolecules - and their role in the life of organisms. Let's figure out where vitamins are found, in what quantities a person needs them, and why the daily dose vitamin C more than all other vitamins, and how it affects the quality of hair and blood vessels vessels. Let's learn about water-soluble and fat-soluble vitamins. We will carry out qualitative reactions to vitamin C and check its content in food products.

LESSON 11. CHEMISTRY OF TEA.

Consider plants as sources of chemicals. Let's take a break for tea: let's talk about the substances contained in tea - caffeine, tannin and chlorophyll - and their biological role. Let's carry out qualitative reactions on tannin, make ink from tea and isolate caffeine.

LESSON 12. MINERALS.

Let's talk about what minerals are and how they are formed. Let's dissolve malachite and carry out qualitative reactions on the metals it contains. Let's dissolve the shell and coral, and use the pigment obtained by dissolving the coral as an acid-base indicator. Let's bleach the coral with heat and make the fluorite glow.
