What is Metabolism?
Metabolism, is the set of chemical reactions that happen in the cells of living organisms to sustain life. These processes allow organisms to grow and reproduce, maintain their structures, and respond to their environments. The word metabolism can also refer to all chemical reactions that occur in living organisms, including digestion and the transport of substances into and between different cells, in which case the set of reactions within the cells is called intermediary metabolism or intermediate metabolism.
Metabolism is usually divided into two categories. Catabolism breaks down organic matter, for example to harvest energy in cellular respiration. Anabolism uses energy to construct components of cells such as proteins and nucleic acids.
The chemical reactions of metabolism are organized into metabolic pathways, in which one chemical is transformed through a series of steps into another chemical, by a sequence of enzymes. Enzymes are crucial to metabolism because they allow organisms to drive desirable reactions that require energy and will not occur by themselves, by coupling them to spontaneous reactions that release energy. As enzymes act as catalysts they allow these reactions to proceed quickly and efficiently. Enzymes also allow the regulation of metabolic pathways in response to changes in the cell’s environment or signals from other cells.
Can Raspberry Ketones affect Weight Loss?
When given to mice in high doses (up to 2% of food intake), raspberry ketone has been shown to prevent high-fat-diet-induced elevations in body weight. This effect is reported to stem from the alteration of lipid metabolism, increasing norepinephrine-induced lipolysis. Although products containing this compound are marketed for weight loss, this effect has not been studied in humans.
Red raspberry is a plant that is the source of a widely eaten, tasty, sweet berry. However, red raspberry fruit and leaf have also been used as medicine for centuries. The therapeutic use of raspberry leaf was first described in 1597 in a book called “The Herbal,” or “A General History of Plants.” Today, red raspberry leaf and fruit are still used as medicine.
What are Raspberry Ketones?
Red raspberry leaf is used for gastrointestinal (GI) tract disorders, including diarrhea; for respiratory system disorders, including flu and swine flu; and for heart problems, fever, diabetes, and vitamin deficiency. It is also used to promote sweating, urination, and bile production. Some people use it for general “purification of skin and blood.”
Some women use raspberry leaf for painful periods, heavy periods, morning sickness associated with pregnancy, preventing miscarriage, and easing labor and delivery.
Red raspberry leaf is applied directly to the skin for sore throat and skin rash.
In foods, red raspberry fruit is eaten and processed into jams and other foods. Red raspberry leaf in small quantities is a source of natural flavoring in Europe.
The appropriate dose of red raspberry depends on several factors such as the user’s age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for red raspberry. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
