Oxygen

Products Oxygen is commercially available in the form of compressed gas cylinders (oxygen cylinders) with a white color as a compressed gas. In many countries, it is available from PanGas, for example. Structure and properties Oxygen (symbol: O, elemental: O2, atomic number: 8, atomic mass: 15,999) is present as dioxygen (O2, O=O) as a colorless, … Oxygen

Lipids

Structure and properties Lipids are characterized by being soluble in organic (apolar) solvents and generally sparingly soluble or insoluble in water. They have lipophilic (fat-loving, water-repellent) properties. Lipids also exist, with polar structural elements such as the phospholipids or ionized fatty acids. They are called amphiphilic and can form lipid bilayers, liposomes and micelles. For … Lipids

Chemical Elements

Structure of matter Our earth, nature, all living things, objects, the continents, mountains, oceans and we ourselves are made of chemical elements that are connected in different ways. Life has come into being through the connection of elements. Chemical elements are atoms with the same number of protons in the nucleus. The number is called … Chemical Elements

Nucleic Acids

Structure and properties Nucleic acids are biomolecules found in all living things on Earth. A distinction is made between ribonucleic acid (RNA, RNA, ribonucleic acid) and deoxyribonucleic acid (DNA, DNA, deoxyribonucleic acid). Nucleic acids are polymers composed of so-called nucleotides. Each nucleotide consists of the following three units: Sugar (carbohydrate, monosaccharide, pentose): ribose in RNA, … Nucleic Acids

Amide

Definition Amides are organic compounds containing a carbonyl group (C=O) whose carbon atom is bonded to a nitrogen atom. They have the following general structure: R1, R2 and R3 can be aliphatic and aromatic radicals or hydrogen atoms. Amides can be synthesized with a carboxylic acid (or a carboxylic acid halide) and an amine using … Amide

Amines

Definition Amines are organic molecules containing nitrogen (N) atoms bonded to carbon or hydrogen atoms. They are formally derived from ammonia, in which hydrogen atoms have been replaced by carbon atoms. Primary amines: 1 carbon atom Secondary amines: 2 carbon atoms Tertiary amines: 3 carbon atoms The functional group is called the amino group, for … Amines

Carbohydrates: Role in Diet

Products Carbohydrates (“sugars”) are found in many natural and processed foods, pharmaceuticals, medical devices, and dietary supplements. For example, foods containing carbohydrates include pasta, cereals, flour, dough, bread, legumes, potatoes, corn, honey, sweets, fruits, sweet beverages, and dairy products. Structure Carbohydrates are natural products and biomolecules that are usually composed of only carbon (C), hydrogen … Carbohydrates: Role in Diet

Vitamins Role in the Body

Products Vitamins are commercially available in the form of pharmaceuticals, dietary supplements, medical devices, cosmetics, and foods, among others. Available dosage forms include, for example, tablets, effervescent tablets, syrups, direct granules and injectables. Vitamins are also combined with other active ingredients and, in particular, with minerals and trace elements in a fixed manner. The name … Vitamins Role in the Body

Therapeutic Proteins

Products Therapeutic proteins are usually administered in the form of injection and infusion preparations and must be stored in a refrigerator. The first recombinant protein to be approved was human insulin in 1982. Some proteins, for example, are also available in tablet, capsule, and powder form and can be stored at room temperature, such as … Therapeutic Proteins

Amino Acids

Products Some preparations containing amino acids are approved as medicinal products. These include, for example, methionine tablets or infusion preparations for parenteral nutrition. Amino acids are also marketed as dietary supplements, such as lysine, arginine, glutamine, and cysteine tablets. Protein powders such as whey protein can also be counted as amino acid supplements. Amino acids … Amino Acids

Monosaccharides

Products Pure monosaccharides are available in specialty stores, such as pharmacies and drugstores. The best-known monosaccharides include glucose (grape sugar), fructose (fruit sugar) and galactose (mucilage sugar). Structure and properties Monosaccharides are the simplest carbohydrates (“sugars”), consisting of carbon (C), hydrogen (H), and oxygen (O) atoms. The organic compounds have the general formula Cn(H2O)n. There … Monosaccharides

Nitrogen

Products Nitrogen is commercially available as a compressed gas in pressurized cylinders and as a liquid in cryogenic containers, among other products. Structure and properties Nitrogen (N, atomic mass: 14.0 u) is a colorless and odorless gas that is present in over 78% of air. It is a chemical element with atomic number 7 and … Nitrogen
