What Are Lipids? - Definition, Structure & Classification Of Lipids
Lipids are the polymers of fatty acids that contain a long, non-polar hydrocarbon chain with a small polar region containing oxygen. The lipid structure is explained in the diagram below: Lipids can be classified into two main classes: A nonsaponifiable lipid cannot be disintegrated into smaller molecules through hydrolysis.
23.1: Structure and Classification of Lipids
We will discuss the various kinds of lipids by considering one subclass at a time and pointing out structural similarities and differences as we go. Fatty acids are carboxylic acids with 12-22 carbon atoms connected in a long, unbranched chain. As shown in the diagram above, most lipids are classified as esters or amides of fatty acids.
Lipid Types and Structures – Nutrition: Science and Everyday ...
There are three main types of lipids: triglycerides, phospholipids, and sterols. On this page, we’ll learn about the structures of these three types of lipids, as well as their functions in the body and where you can find them in foods.
Lipids – Function, Structure, Definition of Lipids - GeeksforGeeks
Feb 14, 2024 · Lipids are a group of organic molecules that play essential roles in the structure and function of living organisms. They are characterized by their hydrophobic (water-repellent) nature and include compounds such as fats, oils, phospholipids, and steroids.

Molecular Structure of Lipids (With Diagram) - Biology Discussion
Simple lipids contain a trihydric alcohol, glycerol and long chain fatty acids. The carboxyl groups of the fatty acids are ester-linked to the hydroxyl groups of glycerol. The fatty acids present in simple lipids have generally 16 or 18 carbon atoms and they may be saturated or unsaturated.
Simple Lipid - an overview | ScienceDirect Topics
In general, two lipid classes can be distinguished: simple lipids, yielding maximum two primary hydrolysis products after saponification; and complex lipids, yielding three or more hydrolysis products. Triglycerides, natural waxes and sterol esters are examples of simple lipids as they yield fatty acids and glycerol, fatty acids and an ...
Lipid - The Definitive Guide - Biology Dictionary
Feb 27, 2021 · Lipids are divided into eight categories: glycerolipids, glycerophospholipids, sphingolipids, fatty acyls, sterol lipids, prenol lipids, saccharolipids, and polyketides. A lipid has multiple functions in the human body, from cell membrane construction to energy storage.
