Organic Chemistry in Viticulture and Enology

Objectives and competences

The objective of this course is to resume and upgrade the knowledge in organic chemistry, got in the secondary school. Special emphasis is given to the basic knowledge of organic chemistry such as fundamentals of reactions of organic compounds. These parts are necessary for the understanding of the phenomena in the environment and for the successful study in more specialised subjects.

Prerequisites

Knowledge of General and Inorganic Chemistry.

Content

Carbohydrates: definition and classification, monosaccharides (general properties, stereochemistry, hexoses, monosaccharides: cyclic structures, properties), disaccharides, polysaccharides;

lipids: what are lipids ?, fatty acids, fats and oils, the properties of fats and oils, soaps, waxes, phospholipids, glycolipids, cell membrane, steroids: cholesterol;

Protein: amino acids (general characteristics, reactions of amino acids), a peptide bond, classification and structure of proteins, silk, wool, collagen, myoglobin, electrochemical properties of proteins, denaturation of proteins.

EXERCISES
Practical laboratory exercises:
==> Organic synthesis;
==> Esterification;
==> Fractional distillation;
==> Synthesis of polymers, condensation

Intended learning outcomes

Students will gain a basic knowledge of organic chemistry, which will help them to understand the chemical changes and reactions that take place in the vines and grapes during the ripening of grapes and processing technology and wine (polyphenols, acids, sugars, waxes, lipids, flavor).
