PROTEIN & AMINO
ACIDS :
COMPOSITION AND
METABOLISM OF PROTEIN
AND AMINO ACIDS
,INTRODUCTION:
Proteins are essential macromolecules
composed of amino acids that play crucial
roles in various biological processes. Amino
acids are the building blocks of proteins and
are involved in the synthesis, degradation,
and metabolism of proteins within the human
body. Understanding the composition and
metabolism of proteins and amino acids is
fundamental to comprehending their
importance in maintaining overall health and
functionality.
, I. AMINO ACIDS:
STRUCTURE OF
AMINO ACIDS:
1. Amino Group (-NH2):
The amino group is composed of a
nitrogen atom bonded to two hydrogen
atoms.
It is the primary site of nitrogen
incorporation into proteins.
The amino group acts as a base,
capable of accepting a proton to form
an ammonium ion (NH3+).
2. Carboxyl Group (-COOH):
The carboxyl group consists of a
carbon atom double-bonded to an
