Five Sense BiochemistryLove thy Lipids
Lipid Chemistry Main Elements of Lipids: Carbon hydrogen & oxygen The ratio of hydrogen to carbon is greater than 2:1
Lipid Chemistry Lipids are non-polar, hydrophobic moleculesHow do lipids behave in the presence of polar molecules such as water? Lipids include fats, phospholipids, waxes & steroids
Function of Fats Energy storageFats contain 9 calories/gram whereas carbohydrates contain 4 calories/gram
Fats Fats are composed of glycerol & three fatty acids (tri-glyceride)
Saturated Fat Study the pattern of carbon & hydrogen bonding—why do you think this is a saturated fat?
Unsaturated Fat Study the pattern of carbon & hydrogen bonding—why do you think this is a unsaturated fat?
Trans Fats What makes trans fats different than other unsaturated fats?
Phospholipids Similar to a fat, but contains only two fatty acids and a phosphate group. Polar heads & non-polar tails Where are phospholipids found in cells?
Steroids (Sterols) Lipids with four fused rings & no fatty acidsCholesterol is found in cell membranes & plays a role in hormone synthesis
KEY CONCEPT Carbon-based molecules are the foundation of life.
Biochemistry Part V Lipids. Lipids A class of organic molecules that are insoluble in water A class of organic molecules that are insoluble in water There.
Ch. 5.3: LIPIDS Objectives:
AP Biology Intro to Organic Molecules & Lipids AP Biology Life is based on Carbon Carbon atoms are versatile building blocks Special bonding properties.
LIPID REVIEW Dr. E. Lipids A. Hydrophobic B. Hydrophillic C. Nonpolar D. Polar E. Both A & C F. Both A and C.
Lipid Review What are the four examples of lipids? 2.
The Organic Nutrients: Building Blocks of Life 1. Carbohydrates 2.Lipids 3.Proteins 4.Nucleic Acids.
Insoluble Biological Molecules
Examples Fats Oils Waxes Steroids Functions Long-term energy storage Main component of cell membranes Hormones Insulation/cushioning.
Fats (an example of a lipid) Glycerol – Has three –OH groups – Polar molecule Soluble in water Fatty Acids – Long chains of hydrocarbons Insoluble in water.
Molecules of Life. Section 2 Molecules of Life Chapter 3 Carbohydrates Carbohydrates are organic compounds composed of carbon, hydrogen, and oxygen in.
Lipids Hydrophobic Elements: C H O Ratio of H:O= H greater than O C 57 H 110 O 6.
Macromolecules Carbohydrates & Lipids
Concept 5.3: Lipids include fats and steroids.. Lipids Group of organic compounds that include fats, oils, and waxes. Composed of carbon, hydrogen, and.
Lipids. Lipids are composed of: Carbon Hydrogen Oxygen BUT: Lipid molecules have a larger number of Carbon and Hydrogen and a smaller number of Oxygen.
Lipids IB Biology Topic 3.
LIPIDS --- Fats & Oils. LIPIDS include: fats oils cholesterol phospholipids.
Notes: Unit 1--Lipids Name Date Hour. (1) What is a lipid? Type of Biomolecule Means “fat”
Lipids. Characteristics of Lipids NONPOLAR (neutral) DO NOT dissolve in water Hydrophobic Hydrophobic (at least part of the molecule)(at least part.
