Chemistry of Carbohydrates. Chemistry of Carbohydrates. Definition of carbohydrates: First Definition (Old definition) : Carbohydrates are substances containing carbon, hydrogen and oxygen having the general formula CnH2nOn . (C3 H6 O3)

Nutrition Science and Application Lori A. Smolin and Mary B. Grosvenor John Wiley & Sons, Inc. Chapter 4 Carbohydrates: Sugars, Starches, and Fiber. 4-1. Carbohydrate in the Diet. Basis of our diet Can be less refined or more refined Refining decreases micronutrients and fiber

Molecules of Life. Molecules of Life. Molecules of life are synthesized by living cells Carbohydrates Lipids Proteins Nucleic acids. Organic Compounds. Consist primarily of carbon and hydrogen atoms Carbon atoms bond covalently with up to four other atoms, often in long chains or rings

CARBOHYDRATE ANALYSIS. SFA3023 FOOD ANALYSIS. INTRODUCTION. Classification of carbohydrates (CHO) Monosaccarides Disaccharides Oligosaccharides Polysaccharides Digestible Non-digestible. Sample Preparation for mono-, di- and oligosaccharides

Molecules of Life. Chapter 3 Part 1. Impacts, Issues: Fear of Frying. Trans fats in hydrogenated vegetable oil raise levels of cholesterol in our blood more than any other fat, and directly alter blood vessel function. Organic Molecules. All molecules of life are built with carbon atoms

CARBOHYDRATES. Medical Biochemistry Molecular Principles of Structural Organization of Cells. CARBOHYDRATES Are hydrated carbon molecules [C n H 2n O n or (CH 2 O) n ], They are virtually ubiquitous because they have such a wide range of structures and functions Structure:

Chapter 8 (part 1). Carbohydrates. Carbohydrates. Most abundant class of biological molecules on Earth Originally produced through CO 2 fixation during photosynthesis. Roles of Carbohydrates. Energy storage (glycogen,starch) Structural components (cellulose,chitin) Cellular recognition

Glycoconjugates. Carbohydrates covalently linked to a protein or lipid. Proteo glycans Glyco proteins Glyco lipids. act as informational carrier in: cell-cell recognition, cell-cell adhesion, cell migration, immune response , …. Glycoconjugates: 1. Proteo glycans.

Carbohydrates. Carbohydrate. hydrate of carbon – C n (H 2 O) m Glucose -blood sugar- C 6 H 12 O 6 or C 6 (H 2 O) 6 Sucrose -table sugar- C 12 H 22 O 11 or C 12 (H 2 O) 11. Not all carbohydrates have this exact form – old habits die slow or sometimes never at all. Monosaccharides.
