ALL BIOMOLECULES CONTAIN CARBONCarbon has 4 valence electrons. Carbon has the ability to form more compounds than any other element.
Large, complex molecules Made from simple repeating unitsBiomolecules Large, complex molecules Made from simple repeating units 4 Major Groups of Biomolecules Carbohydrates Proteins Lipids Nucleic Acids
CARBOHYDRATES Sugars that provide short term energy to cellsPrimarily come from plants Referred to as “CHO’s” because carbohydrates are made of carbon, hydrogen and oxygen atoms
Functions of Carbohydrates:Main Source of Energy For Cells 80% of our Energy intake 2. Structural Support From chitin and cellulose 3. Cell Recognition short sugar chain identify cells
The Carbon Cycle = Recycling Carbon
MONOSACCHARIDES: Single sugar moleculeThere are three different monosaccharides GLUCOSE : (5 Carbon ring) GALACTOSE: (5 Carbon ring) FRUCTOSE: (4 Carbon ring)
A CLOSER LOOK AT GLUCOSEGlucose is the principal sugar found in blood Molecular Formula is C6H12O6
DISACCHARIDES: two monosaccharides bonded togetherExamples MALTOSE : “Beer sugar” Made of GLUCOSE + GLUCOSE
DISACCHARIDES: CONTINUED two monosaccharides bonded togetherExamples 2) SUCROSE: “TABLE SUGAR” Made of GLUCOSE + FRUCTOSE
DISACCHARIDES: CONTINUED two monosaccharides bonded togetherExamples 3) LACTOSE : “Milk sugar” Made of GLUCOSE + GALACTOSE
POLYSACCHARIDES: Large Carbohydrate Molecules (complex)1. GLYCOGEN ANIMAL STORAGE OF CHO’S HUMAN MUSCLE AND LIVER CELLS STORE GLYCOGEN FOR EMERGENCY SUPPLIES BRANCHED CHAIN OF GLUCOSE
POLYSACCHARIDES: 2. STARCH PLANT STORAGE OF CHO’SHUMAN’S ARE ABLE TO BREAKDOWN AND USE FOR ENERGY EX) POTATO COILED CHAIN OF GLUCOSE
POLYSACCHARIDES: Large Carbohydrate Molecules (complex)3. CELLULOSE LONG STRAIGHT CHAIN OF GLUCOSE MAKES UP PLANT CELL WALLS HUMANS CANNOT DIGEST CELLULOSE AND CANNOT BE USED FOR ENERGY
WHAT DO THESE HAVE IN COMMON
Carbohydrates Properties Controlled by Structure
Carbohydrates Objectives: Ability to define the term biological chemicals Understand the structure & classification of carbohydrates Knowledge of the functions.
ORGANIC COMPOUNDS Molecules formed from different combinations of carbon and hydrogen atoms May also contain atoms of one or more of the following:
CARBOHYDRATE REVIEW. A carbohydrate is: A. An organic compound B. A Biomolecule C. An Inorganic compound D. Ionic compound E. Both a and B.
compounds that contain carbon are called______________ Organic.
Biological Molecules Carbohydrates Proteins Lipids Nucleic Acids.
Organic Molecules. Organic Compounds Contain C and H Often form long chains of carbon atoms linked by covalent bonds Macromolecules = large organic.
Biologically Important Molecules. There are four biologically important groups of molecules found in living organisms. They are: Carbohydrate.
Carbohydrates Lab 6. Carbohydrates Carbohydrates are compounds of carbon (C), hydrogen (H) and oxygen (O). Usually found 1C:2H:1O. Usually grouped as.
All organisms are made of four types of carbon-based molecules: 1. Carbohydrates 2. Lipids 3. Proteins 4. Nucleic Acids The molecules have different.
Lets Carb Up!!!. Carbohydrates - Composition Made of… (Hint: look at the name) – Carbon – Hydrogen – Oxygen.
–Carbohydrates –Lipids (fats) –Proteins –Nucleic Acids Organic molecules are the molecules in living things There are four types of organic (carbon-based)
But what’s so special about Carbon? Carbon has 4 valence electrons Can readily form and break bonds Forms long chains Can form single, double, and triple.
ORGANIC COMPOUNDS The Chemistry of LIFE!!. All living organisms require 4 types of Organic Compounds: 1.Carbohydrates 2.Lipids 3.Proteins 4.Nucleic Acids.
MACROMOLECULES. Four Types of Macromolecules 1. Carbohydrates 2. Lipids 3. Proteins 4. Nucleic Acids.
