What is bilirubin? Bilirubin Test, And Urine Bilirubin Test

What is bilirubin? Bilirubin is a molecule formed by the breakdown of red blood cells and other cells with porphyrins. Red blood cells carry special molecules, called hemes (a type of porphyrin), that house an iron atom. This arrangement allows red blood cells to carry oxygen. When blood cells break down, they release heme into … Read more

Coenzyme Definition, functions, Types, and Examples

Coenzyme Definition A coenzyme is a non-protein organic compound that binds with an enzyme to catalyze a reaction. Coenzymes are often widely called cofactors, but they are chemically different. A coenzyme cannot work on its own, but it can be reused multiple times when combined with an enzyme. Coenzyme functions An enzyme without a coenzyme is called apoenzyme. … Read more

Biochemistry Definition, History, Research And, Careers

Biochemistry Definition Biochemistry is the study of chemical reactions occurring inside organisms. It combines elements from both biology and chemistry. Biochemistry became a separate discipline in the early 20th century. Biochemists study relatively large molecules such as proteins, lipids, and carbohydrates, which are important in metabolism and other cellular activities; They also study molecules such … Read more

Fatty Acids, Role, Types ,Unsaturated And Saturated

What is Fatty acids? Fatty acids are made up of hydrocarbon chains that end with carboxylic acid groups. Fatty acids and their associated derivatives are the main components of lipids. The length and degree of saturation of the hydrocarbon chain are highly variable between each fatty acid and dictates the associated physical properties (eg, melting … Read more

Electron Transport Chain (ETC), Steps, and, Diagram

An electron transport chain is a group of proteins that transfer electrons through a membrane into the mitochondria to form a proton gradient that results in the creation of adenosine triphosphate (ATP). ATP is used by the cell as energy for the metabolic processes of cellular functions. Electron Transport Chain Electron transport systems, also called … Read more

Krebs cycle, Definition, Location, Enzymes, Products and Steps

Krebs cycle Definition The Krebs cycle, also known as the citric acid cycle or TCA cycle, is a series of reactions that take place in the mitochondria that results in the oxidation of acetyl CoA to release carbon dioxide and hydrogen atoms that then lead to water formation. This cycle is called the citric acid … Read more

What is a peptide? Peptide bond definition

What is a peptide? A peptide is a short-chain made up of amino acids that, together with other peptides, forms a protein. The number of amino acids in a peptide can range from two amino acids to fifty amino acids. Depending on the number of amino acids present in the peptide, the peptides are of … Read more
