BIO Notes On Organic Chemistry Essay, Research Paper

The chemistry of life

(Living things made mostly of carbohydrates, fat and protein)

CARBOHYDRATES energy producer

· Contain carbon, hydrogen and oxygen

· Glucose is the simplest (dissolves easily in water) monosaccharide

· Starch is also common (solid, lots of glucose molecules in a chain (condensation)) disaccharide

· Starch is broken down into glucose as well (add wateràhydrolysis)

FAT energy producer insulation and energy store

· Contain carbon, hydrogen and oxygen

· Contains more carbon + hydrogen

· Fat molecule is made up of glycerol and fatty acids.

· Condensation and hydrolysis play parts here?

PROTEIN

· Contain carbon, hydrogen, oxygen, nitrogen (and sulphur)

· Made of blocks (amino acids) and links (peptide links)

· 22 amino acids in nature

· Hydrolysis à chain of proteins split (polypeptides) then broken to small amino acids

· Reverse in condensation

· Soluble proteins make up enzymes.

· Denaturalisation occurs when molecule shape changes when heated.

CHEMICAL REACTIONS

· Occur mainly in gut and cells

· Reactions in cells is metabolism

· Breaking down or joining options

· All reactions are catalysed by enzymes.

Enzymes

IMPORTANCE

· To speed up reactions
