FAQT ABBREVIATION SKIN
The location of the tissue determines its metabolic profile: visceral fat is located within the abdominal wall (i.e., beneath the wall of abdominal muscle) whereas subcutaneous fat is located beneath the skin (and includes fat that is located in the abdominal area beneath the skin but above the abdominal muscle wall). Adipose tissue also secretes the hormone leptin. These metabolic activities are regulated by several hormones (e.g., insulin, glucagon and epinephrine). Under energy stress these cells may degrade their stored fat to supply fatty acids and also glycerol to the circulation. Adipocytes (fat cells) store fat derived from the diet and from liver metabolism. In animals, adipose tissue, or fatty tissue is the body's means of storing metabolic energy over extended periods of time. For comparison, a mouse with a normal amount of adipose tissue is shown on the right. The obese mouse on the left has large stores of adipose tissue. This helps to protect vital organs, until such time as the offending substances can be metabolized or removed from the body by such means as excretion, urination, accidental or intentional bloodletting, sebum excretion, and hair growth. When a particular substance, whether chemical or biotic, reaches unsafe levels in the bloodstream, the body can effectively dilute-or at least maintain equilibrium of-the offending substances by storing it in new fat tissue. Fat also serves as a useful buffer against a host of diseases. Vitamins A, D, E, and K are fat-soluble, meaning they can only be digested, absorbed, and transported in conjunction with fats.įats play a vital role in maintaining healthy skin and hair, insulating body organs against shock, maintaining body temperature, and promoting healthy cell function. įats are also sources of essential fatty acids, an important dietary requirement. Each gram of fat when burned or metabolized releases about 9 food calories (37 kJ = 8.8 kcal). In humans and many animals, fats serve both as energy sources and as stores for energy in excess of what the body needs immediately. 5.4 Omega-three and omega-six fatty acids.5.3.5 Natural "trans fats" in dairy products.5.2.1 Insulin resistance and sensitivity.Dietary fats are also the carriers of some flavor and aroma ingredients and vitamins that are not water-soluble. The human body can produce the fat it requires from other food ingredients, except for a few essential fatty acids that must be included in the diet. They are a major and dense source of food energy for many animals and play important structural and metabolic functions, in most living beings, including energy storage, waterproofing, and thermal insulation. įats are one of the three main macronutrient groups in human diet, along with carbohydrates and proteins, and the main components of common food products like milk, butter, tallow, lard, salt pork, and cooking oils.

In this sense, besides the triglycerides, the term would include several other types of compounds like mono- and diglycerides, phospholipids (such as lecithin), sterols (such as cholesterol), waxes (such as beeswax), and free fatty acids, which are usually present in human diet in smaller amounts. The term may also be used more broadly as a synonym of lipid-any substance of biological relevance, composed of carbon, hydrogen, or oxygen, that is insoluble in water but soluble in non-polar solvents. The term often refers specifically to triglycerides (triple esters of glycerol), that are the main components of vegetable oils and of fatty tissue in animals or, even more narrowly, to triglycerides that are solid or semisolid at room temperature, thus excluding oils. In nutrition, biology, and chemistry, fat usually means any ester of fatty acids, or a mixture of such compounds, most commonly those that occur in living beings or in food.
