Download Describe in simple terms the chemical nature of sugars, proteins

Buffers convert strong acids and bases to weak acids and bases, which keeps the pH
in the desired range. There are three buffer systems, the protein buffer system, the
carbonic acid-bicarbonate buffer system, and the phosphate buffer system.
The carbonic acid-bicarbonate buffer system:
When the pH level varies from the normal range, the carbonic acid-bicarbonate
system allows the body to automatically balance out the pH level. It converts the
strong acids and bases to weak acids and bases.
Describe in simple terms the chemical nature of sugars, proteins,
lipids, nucleotides and enzymes:
Sugars – a simple sugar, known as a monosaccharide, is made up of 3 to 7 carbon
atoms arranged in a ring. A disaccharide is two monosaccharides, such as glucose and
fructose equals sucrose. A polysaccharide is a long chain of monosaccharides and can
be either straight or highly branched.
Proteins – the most abundant organic components of the human body (20% of body
weight). Vary in size, shape, and function. They are long chains of amino acids, and
there are 20 different amino acids. Carrier of haemoglobin, etc.
Lipids – hydrophobic, contain carbon, hydrogen and oxygen.
Nucleotides – molecules made up of a base, a sugar, and a phosphate.
Enzymes – proteins, catalysts.
List the important roles that sugars, proteins, lipids, nucleotides and
enzymes play in the human body:
