Protein structure is the three-dimensional arrangement of atoms in a protein molecule. Proteins are polymers â specifically polypeptides â formed from sequences of amino acids, the monomers of the polymer. A single amino acid monomer may also be called a residue (chemistry) indicating a repeating unit of a polymer.
Developmental disability is a diverse group of chronic conditions that are due to mental or physical impairments. Developmental disabilities cause individuals living with them many difficulties in certain areas of life, especially in language, mobility, learning, self-help, and independent living.
Other Developmental Disabilities are those handicapping conditions similar to that require treatment (i.e., care and management) similar to that required by individuals with intellectual disability. This does not include handicapping conditions that are solely psychiatric or physical in nature. The handicapping conditions must occur before age 18, result in a substantial handicap, be likely to continue indefinitely, and involve brain damage or dysfunction. Examples of conditions might include intracranial neoplasms, degenerative brain disease or brain damage associated with accidents.
