Another word for "fats." Lipids can be more formally defined as substances such as a fat‚ oil or wax that dissolves in alcohol but not in water. Lipids contain carbon‚ hydrogen and oxygen but have far less oxygen proportionally than carbohydrates. They are found in places as diverse as egg yolks and the human nervous system and are important component of plant‚ animal and microbial membranes A fatty or waxy are organic compound that is readily soluble in nonpolar solvent (e.g. ether)

LAB 9: DATE: 25TH January‚ 2011. FORM CLASS: L6 3 SUBJECT: Biology TITLE: Enzymes AIM: To investigate the effect of temperature on the enzyme lipase INTRODUCTION: The phenomenon of catalysis makes possible biochemical reactions necessary for all life processes. Catalysis is defined as the acceleration of a chemical reaction by some substance which itself undergoes no permanent chemical change. The catalysts of biochemical reactions are enzymes and are responsible for bringing about almost

All Biomolecules have certain functions and these molecules all have a unique structure which is why they function in these ways. These molecules are known collectively as macromolecules‚ these molecules are grouped into four main categories which each have there own structure. These structures are the key to the macromolecules functions as each of them do a specific task in the body. Macromolecules are grouped into carbohydrates‚ nucleic acids‚ proteins‚ and lipids. In most cases macromolecules

CHAPTER 1 INTRODUCTION Background of the Study Solid waste management is increasingly seen as a major issue in the country due to high rates of urbanization and increasing per capita solid waste generation with greater affluence (Petnamsin‚ et al.‚ 2000). A major component of solid waste is resin based plastic. Plastics posses many properties such as water resistance and long life‚ that makes them perfect candidates for packaging. Unfortunately‚ the properties that make this product suitable

Triacylglycerol TCP FST4826 6 Mono- and Diacylglycerols TCP FST4826 7 Mono- and Diacylglycerols • Mono- and diacylglycerols are mono- and diesters of fatty acids and glycerol. • Emulsifiers. • They are prepared commercially by the reaction of glycerol and triacylglycerols or by the esterification of glycerol and fatty acids. • Formed in the intestinal tract as a result of the normal digestion of triacylglycerols. • Very minor amounts in both animal fats and vegetable oils.
Premium Fatty acid
Condensation polymers are formed by linking together monomers with the release of a smaller molecule‚ such as water or hydrogen chloride. An example of this type of polymerization is the formation of a laminating resin called Glyptal from the reaction of glycerol and phthalic acid. The molecule that is

An Assignment on Rice Bran Oil Technology Oil: Oils are esters of glycerol and fatty acid. In other words‚ oils are tri-glycerol ester of fatty acid. Hence ester of glycerol is known as glycerides and fatty acids both are saturated and unsaturated. Oils are liquid at ordinary temperature. Example: Rice bran oil‚ Coconut oil‚ Soybean oil‚ palm oil. Etc. Fats: Fats are same as oil‚ i.e. Fats are esters of glycerol and fatty acid‚ except that fat is solid at ordinary temperature. The melting point

Organic Chemistry/Biochemistry 1: Compounds Important to Life • Biologists classify compounds into organic compounds and inorganic compounds. Organic Compound: a compound that is derived from living things and contains carbon Inorganic Compound: a compound generally derived nonliving things • Water Water is an inorganic molecule with unique properties that make it one of the most important compounds for living things. In the water molecule (H2O)‚ the hydrogen and oxygen atoms bond
