How does the structure of an amino acid relate to its function in cellular processes

The function of the protein is determined by the sequence of the amino acid. The function of protein is determined by its shape, and the shape of the protein is determined by the sequence of nucleotide which is present in the gene which encodes for the protein.

These sequence determine the primary, secondary and tertiary structure of protein which depends mainly on the folding of the protein. And the biological function of the protein such as enzymatic, signalling and structural is determined by these structure.

Example: Each enzyme has a active site where substrate binds in order to carry out reactions. The shape of amino acid depends on the sequence of amino acid and protein folding.

Thus, the structure of amino acid sequence is dependent on the its function.

"menstrual cycle is a complex cycle that consists of several processes. order of occurrence of steps in menstrual cycle are as follows:

1. high progesterone levels maintain the endometrium lining of the uterus.

2. endometrium lining breaks down and low levels of estrogen stimulate the pituitary to release fsh and lh.

3. fsh and lh stimulates the follicles to develop and the oocyte to produce estrogen.

4. rising estrogen levels suppress fsh production and development of other follicles.

5. a spike in lh causes follicle to rupture.

6. a breakdown of corpus luteum causes progesterone level to drop."
