Practical experiments, case studies and other activities for 11—16 year olds to learn about the chemistry of fats in the context of food and diet. In this collection of activities, students explore a variety of chemical ideas relating to fats and oils or lipids in our diets. Created for 11—16 year olds, the resources use familiar examples to provide context for activities ranging from class experiments including a cooking-based investigation to case studies, giving students the opportunity to apply what they have learned.

In biology and biochemistry , a lipid is a macro biomolecule that is soluble in nonpolar solvents. The functions of lipids include storing energy, signaling , and acting as structural components of cell membranes. Biological lipids originate entirely or in part from two distinct types of biochemical subunits or "building-blocks": ketoacyl and isoprene groups. 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.

Handbook of Food Chemistry pp Cite as. Fats and oils are an important dietary component and contribute to the nutritional and sensory quality of foods. This chapter focuses on the chemical composition of fats and oils and how these compositions affect the functional properties of fats and oils in foods. The focus will remain on the most economically and commercially important fats and oils that are widely used as or in food products. Skip to main content.

This book is composed of two sections. The first section deals with the presentation of standard methods and procedure for oleaginous seeds and fruits analysis of oil, fats, and their derivatives. The next section describes the determination procedure of physico-chemical properties of determined oil, fats, and derivatives. Such characteristics include density, refractive index, color, dilatation, acid, ester, iodine value, and moisture and volatile matter content This book will prove useful to analytical chemists and researchers in the allied fields. Section I: Oleaginous Seeds and Fruits 1. Preparation of the sample for analysis Determination of the physical characteristics 1.

Lipid , any of a diverse group of organic compounds including fats , oils , hormones , and certain components of membranes that are grouped together because they do not interact appreciably with water. One type of lipid, the triglycerides , is sequestered as fat in adipose cells , which serve as the energy-storage depot for organisms and also provide thermal insulation. Some lipids such as steroid hormones serve as chemical messengers between cells , tissues , and organs , and others communicate signals between biochemical systems within a single cell. The membranes of cells and organelles structures within cells are microscopically thin structures formed from two layers of phospholipid molecules. Membranes function to separate individual cells from their environments and to compartmentalize the cell interior into structures that carry out special functions. So important is this compartmentalizing function that membranes, and the lipids that form them, must have been essential to the origin of life itself. A lipid is any of various organic compounds that are insoluble in water.
