selüloz
a substance found in the cell walls of plants, providing structure and making up dietary fiber
Cellulose is a type of carbohydrate, specifically a polysaccharide, that forms the structural component of plant cell walls. It is made up of long chains of glucose molecules linked together, providing strength and rigidity to plant cells. While cellulose is indigestible by humans and most animals due to their lack of enzymes capable of breaking it down, it serves as dietary fiber, aiding in digestion and promoting bowel regularity. Cellulose is found in high amounts in plant-based foods such as fruits, vegetables, whole grains, and legumes.
fruktoz
a natural sugar found in fruits and honey, often used to sweeten foods and drinks
Fructose is a type of sugar, classified as a monosaccharide, that is naturally found in fruits, honey, and certain vegetables. It is known for its sweet taste and is often used as a sweetener in processed foods and beverages. When consumed, fructose is absorbed into the bloodstream and transported to the liver, where it is processed and converted into glucose or stored as glycogen for energy. While fructose can provide energy like other sugars, excessive intake, particularly from added sugars in processed foods, has been associated with negative health effects, including obesity, type 2 diabetes, and fatty liver disease.
glikoz
a basic kind of sugar that is a component of carbohydrates and provides energy for many living organisms
Glucose is a type of sugar, known as a monosaccharide, that serves as the primary source of energy for the body's cells. It is found naturally in many foods, including fruits, vegetables, and grains, and is also produced by the body through the breakdown of carbohydrates. Glucose is absorbed into the bloodstream after digestion and is transported to cells throughout the body, where it is used for energy production. Excess glucose is stored in the liver and muscles as glycogen for later use. Maintaining stable blood glucose levels is essential for overall health, as fluctuations can affect energy levels, mood, and long-term health outcomes.
(peptid zinciri)
peptid
a short chain of amino acids linked together, which can function as a building block for proteins or act as a signaling molecule in the body
(karoten pigmenti)
karotenoid
a type of pigment found in plants, algae, and some bacteria, responsible for bright red, yellow, and orange colors and important for photosynthesis and antioxidant activity
enzim
a substance that all living organisms produce that brings about a chemical reaction without being altered itself
Enzymes are special proteins that speed up biological reactions in the body. They help reactions occur more quickly by reducing the amount of energy needed to start them. Enzymes are highly specific, meaning each enzyme typically activates only one type of reaction or a few closely related reactions. They play crucial roles in various bodily functions, including digestion, metabolism, and cellular processes. For example, digestive enzymes aid in breaking down food into smaller molecules that can be absorbed by the body, while metabolic enzymes assist in chemical reactions involved in energy production and the creation of essential molecules. Without enzymes, many vital biochemical reactions would happen too slowly to sustain life processes.
(protein kompleksi)
proteom
the entire set of proteins expressed by a cell, tissue, or organism at a specific time under defined conditions
(nükleotid molekülü)
nükleotid
a molecule that forms the basic building block of DNA and RNA, consisting of a sugar, a phosphate group, and a nitrogenous base
monosakkarit
a simple sugar molecule, the most basic form of carbohydrates that cannot be further hydrolyzed
Monosaccharides are simple sugars, which are the most basic form of carbohydrates. They consist of single sugar molecules that cannot be broken down further into smaller sugars. Common examples of monosaccharides include glucose, fructose, and galactose. These sugars are easily absorbed by the body and serve as a quick source of energy. Monosaccharides are found naturally in fruits, vegetables, and honey, and they are also added to processed foods as sweeteners. In addition to providing energy, monosaccharides play important roles in cellular processes and are essential for overall health and well-being.
(glutamik asit tuzu)
glutamat
a fundamental compound derived from glutamic acid, integral to biological functions and known for its role as a neurotransmitter in the central nervous system
antioksidan
a substance, such as vitamin E, that helps clean the body of harmful substances
An antioxidant is a substance that possesses unique properties to counteract and neutralize harmful molecules called free radicals. Antioxidants can be naturally occurring or synthetic, and common examples include vitamins C and E, beta-carotene, and resveratrol. Antioxidants work by donating electrons to free radicals, thereby preventing or minimizing their damaging effects on cells. They are known for their potential health benefits, including protecting against chronic diseases, reducing inflammation, and promoting overall well-being. Antioxidants can be obtained through a balanced diet rich in fruits, vegetables, whole grains, and other sources known for their antioxidant content.
lipit
any of a class of organic substances that do not dissolve in water that include many natural oils, waxes, and steroids
Lipids are a diverse group of molecules that include fats, oils, and certain components of cell membranes. They are insoluble in water and primarily consist of hydrocarbons, including fatty acids and cholesterol. Lipids serve various essential functions in the body, such as providing energy, insulating and protecting organs, and serving as structural components of cell membranes. Types of lipids include triglycerides, phospholipids, and sterols. Triglycerides, found in fats and oils, are a major source of energy storage in the body. Phospholipids are crucial components of cell membranes, helping to maintain their structure and function. Sterols, such as cholesterol, are important for the production of hormones and vitamin D. While lipids are necessary for health, an imbalance or excessive intake of certain types, particularly saturated and trans fats, can contribute to health issues such as heart disease.
(hücre organeli)
organel
a specialized, membrane-bound structure within a cell that performs specific functions, contributing to the cell's overall structure and function
(mitokondriyal)

(Hücre sıvısı)
Sitoplazma
the gel-like, semifluid substance within a cell that surrounds the organelles, providing a medium for cellular activities, including metabolism, transport of substances, and support for cellular structures
klorofil
a green pigment found in all green plants and cyanobacteria that is responsible for the absorption of the sunlight needed for the photosynthesis process
membran
a thin sheet of tissue that separates or covers the inner parts of an organism
A membrane refers to a thin, flexible layer of tissue that covers, lines, or separates various structures and organs. These membranes serve diverse functions, such as protecting organs, providing structural support, facilitating movement and flexibility, and allowing for the exchange of substances. Examples of membranes in the human body include the mucous membranes that line the respiratory and digestive tracts, the serous membranes that encase organs in protective fluid-filled cavities, and the cell membranes that surround individual cells, regulating the passage of molecules. Membranes are essential for the proper functioning and integration of different body systems.
doku
a group of cells in the body of living things, forming their different parts
Tissue refers to a group or collection of specialized cells that work together to perform a specific function. Tissues can be categorized into four main types: epithelial, connective, muscle, and nervous. Epithelial tissue forms protective barriers and linings, connective tissue provides support and structure, muscle tissue enables movement and contraction, and nervous tissue facilitates communication and electrical signaling. Tissues are the building blocks of organs and systems, playing a vital role in maintaining the body's structure, function, and overall homeostasis.
