What is a Lysozyme?
A Lysozyme is a glycoprotein that is found in many body secretions such as tears, saliva, mucus, and breast milk. It is also found in many foods such as eggs and chicken. Lysozyme is responsible for breaking down the peptidoglycan layer of bacterial cell walls. This layer is responsible for protecting the bacteria from the environment and from being attacked by the host’s immune system. By breaking down this layer, Lysozyme allows the bacteria to be killed and the host’s immune system to be activated.
Structure of Lysozyme
Lysozyme is a globular protein that is composed of 126 amino acids. It is a highly soluble protein that is found in a variety of body fluids, including tears, saliva, and mucus. Lysozyme is a glycoprotein, meaning that it contains sugar molecules attached to its amino acids. The sugar molecules help to stabilize the protein and contribute to its overall function.
The structure of lysozyme is relatively simple, with a beta-barrel shape that is common to many globular proteins. The protein has a hydrophobic core, meaning that it is largely composed of amino acids that interact poorly with water. This core helps to stabilize the protein and keep it in its functional shape. The surface of the protein is covered with sugar molecules and hydrophilic (water-loving) amino acids, which help to attract water and keep the protein in a soluble state.
Examples of Lysozymes
Lysozyme a common enzyme found in many body tissues, including tears, saliva, mucus, and breast milk. Lysozyme used to digest bacteria by breaking down their cell walls. This enzyme is especially important in the early stages of infection, when the body is trying to fight off the bacteria. Lysozyme can also found in some food products, such as raw eggs and chicken.
Mechanism of Action
- Lysozyme is an enzyme that is a part of the immune system. It found in body fluids such as tears, saliva, and mucus. Lysozyme also found in some foods, such as egg whites and milk. This enzyme helps to protect the body by breaking down the cell walls of bacteria.
- Lysozyme is a protein that made up of amino acids. Enzymes are proteins that act as catalysts, which means that they help chemical reactions to happen. Lysozyme works by breaking down a type of molecule called peptidoglycan, which found in the cell walls of bacteria.
- The cell walls of bacteria made up of layers of peptidoglycan. Peptidoglycan made up of sugars and amino acids. Lysozyme works by breaking the bonds between the sugars and amino acids in peptidoglycan. This breaks down the cell wall and kills the bacteria.
- Lysozyme found in many body fluids, such as tears, saliva, and mucus. These fluids help to protect the body by washing away bacteria and other harmful substances. Lysozyme also found in some foods, such as egg whites and milk.
Action of lysozyme
- Lysozyme is a part of the innate immune system. The innate immune system is the body’s first line of defense against infection. It includes physical barriers, such as the skin, and chemical barriers, such as lysozyme.

Function
Lysozyme one of the key enzymes involved in innate immunity, the first line of defense against infection. Lysozyme is a glycoside hydrolase that catalyzes the breakdown of bacterial cell walls by hydrolyzing the bond between N-acetylmuramic acid and N-acetylglucosamine. This action weakens the cell wall, causing the cell to lyse. Lysozyme found in saliva, tears, and other body fluids, as well as in the egg white of many mammals. Lysozyme is one of the few enzymes that can function at both acidic and alkaline pH.
Inhibition
The enzyme tyrosine hydroxylase catalyzes the conversion of the amino acid tyrosine to the catecholamine dopamine. The drug alpha-methyl para-tyrosine inhibits the activity of tyrosine hydroxylase, thereby decreasing the production of dopamine. This can lead to a number of adverse effects, including a decrease in the level of arousal, a decrease in the level of motivation, and a decrease in the level of pleasure.
Non-enzymatic Action
Non-enzymatic actions are those that occur without the use of enzymes. In some cases, the non-enzymatic action is a chemical reaction that occurs spontaneously. In other cases, the non-enzymatic action is a physical process that does not require a chemical reaction. Some of the most common non-enzymatic actions described below.
Browning
- One of the most common non-enzymatic actions is browning. Browning is the process by which food turned from a white or pale color to a brown or black color. The browning reaction is a chemical reaction that occurs spontaneously. The reaction caused by the oxidation of food molecules. The browning reaction accelerated by the presence of oxygen and by high temperatures.
- The browning reaction can produce harmful compounds called advanced glycation end products (AGEs). AGEs can damage cells and contribute to the development of diseases such as diabetes and heart disease. To avoid the harmful effects of AGEs, it is important to minimize the browning reaction. One way to do this is to cook food at low temperatures.
Fermentation
Fermentation is the process of converting sugar into alcohol or vinegar. The fermentation reaction is a chemical reaction that occurs spontaneously. The reaction caused by the action of yeast or bacteria on sugar. The fermentation reaction accelerated by the presence of oxygen. However the fermentation reaction can produce harmful compounds called alcohols.
Enzyme Conformation Changes
- The conformation of an enzyme is important in its ability to catalyze a reaction. It is the shape that the enzyme takes when it is in its active site. The conformation of an enzyme can changed by the presence of a substrate or by a product of the reaction.
- When a substrate binds to the enzyme, the conformation of the enzyme changed so that the substrate can bind to the enzyme. The conformation of the enzyme also changed when a product of the reaction binds to the enzyme. The product can change the conformation of the enzyme so that the enzyme can catalyze another reaction.
