Proteins & Nucleic Acids Proteins make up around 50% of the bodies dry mass and serve many functions in the body including: – Enzymes - Catalysts that.

Amino acid side chains stabilise the enzyme shape.

– Carbohydrates – Lipids (fats) – Proteins – Nucleic Acids Organic molecules are the molecules in living things There are four types of organic (carbon-based)

PROTEINS

Characteristics of Proteins Contain carbon, hydrogen, oxygen, nitrogen, and sulfur Serve as structural components of animals Serve as control molecules (enzymes) Serve as transport and messenger molecules Basic building block is the amino acid

Amino Acid Amine group acts like a base, tends to be positive. Carboxyl group acts like an acid, tends to be negative. “R” group is variable, from 1 atom to 20. Two amino acids join together to form a dipeptide. Adjacent carboxyl and amino groups bond together.

Some Amino Acids

Some More Amino Acids

Still More Amino Acids

Formation of a Dipeptide Dehydration synthesis

Amino Acid + Amino Acid --> Dipeptide Amino Acid + Dipeptide --> Tripeptide A.A. + A.A. + …..+ Tripeptide --> Polypeptide

A protein consists of one or more polypeptide chains.
