Proteins are made up of `alpha` - amino acids. They are actually polypeptides having high molecular mass. Name an optically inactive `alpha` - amino acid found in proteins.

Proteins are made up of alpha - amino acids. They are actually polypeptides having high molecular mass. How do amino acids exist as zwitherion ?

Proteins are made up of alpha - amino acids. They are actually polypeptides having high molecular mass. Give one example each for neutral, acidic and basic alpha - amino acids.

Which is alpha -amino acid?

Proteins are the polymers of alpha - amino acids. The structure and shape of proteins can be discussed at four different levels - namely primary, secondary, tertiary and quaternary Give an account of structure and shape of proteins considering the above levels.

Consider the following statements concerning proteins I. All natural amino acids which are constituents of proteins, are alpha -amino acids. II. alpha -Amino acids are all optically active and have L-configuration. III. alpha -Amino acids are connected by ester linkages. IV. Favourable conformation for the peptide linkages in protein is the alpha -helix arrangement. Of these statements

Aminoacids, as the name suggests, have both an amino group and a carboxyl group in their structure. In addition, all naturally occurring aminoacids (those which are found in proteins) are called L-aminoacids.From this, can you guess from which compound can the simplest aminoacid be made?
