What is the job of a lipid in the body?

Answer 1

The three major purposes of lipids are energy storage, cell membrane development, and serving as a component to hormones and vitamins in the body. In healthcare, physicians order lipid tests or lipid profiles to measure cholesterol and triglycerides in a person's blood. Lipoprotein is the medical term used to define a combination of fat and protein.

Cholesterol is a naturally occurring substance in the body and is comprised of lipids. Cholesterol is separated into two types, high-density lipoprotein (HDL) and low-density lipoprotein (LDL). In a lipid test, the lipoproteins are separated so the level of each can be measured. Lipid tests are often part of preventative routine care, as they help determine whether there is significant risk for artherosclerosis, a hardening of the arteries that interferes with or interrupts blood flow. Lipoprotein levels are measured and dietary changes are usually in order when total cholesterol levels approach or rise above 200 milligrams per deciliter in the blood.

Fatty Acids, also comprised of lipids, are an important dietary concern. Some fatty acids are essential and others are harmful. Fatty acids are categorized as mono-saturated, mono-unsaturated and poly-unsaturated.

Answer 2

Lipids constitute a broad group of naturally occurring molecules that include fats, waxes, sterols, fat-soluble vitamins (such as vitamins A, D, E, and K), monoglycerides, diglycerides, triglycerides, phospholipids, and others. The main biological functions of lipids include energy storage, as structural components of cell membranes, and as important signaling molecules.[4][5]

Lipids may be broadly defined as hydrophobic or amphiphilic small molecules; the amphiphilic nature of some lipids allows them to form structures such as vesicles, liposomes, or membranes in an aqueous environment. Biological lipids originate entirely or in part from two distinct types of biochemical subunits or "building-blocks": ketoacyl and isoprene groups.[4] Using this approach, lipids may be divided into eight categories: fatty acids, glycerolipids, glycerophospholipids, sphingolipids, saccharolipids, and polyketides (derived from condensation of ketoacyl subunits); and sterol lipids and prenol lipids (derived from condensation of isoprene subunits).[4]

Although the term lipid is sometimes used as a synonym for fats, fats are a subgroup of lipids called triglycerides. Lipids also encompass molecules such as fatty acids and their derivatives (including tri-, di-, monoglycerides, and phospholipids), as well as other sterol-containing metabolites such as cholesterol.[6] Although humans and other mammals use various biosynthetic pathways to both break down and synthesize lipids, some essential lipids cannot be made this way and must be obtained from the diet.

Answer 3

Lipids are fat and oils that help our body run a lot of the functions that are required in a metabolism.

Answer 4

lipids like fats or oil in our body act as a reserved energy for the emergency starvation of our tissues...also it acts as a insulator that's why we are not get cool when its cold.
